Price, supply concerns command attention at ICE
Raw-material price and supply issues appeared to overshadow the new- product  and technology showcase that traditionally serves as the focal point of the  Federation of Societies for Coatings Technology's International Coatings Expo (ICE). A good portion of the talk on the floor of Chicago's McCormick Place North included some strongly worded opinions from suppliers on the need for  further raw-material price increases.
Higher prices, suppliers said, are needed to deliver margins and allow investment  in additional production capacity and required maintenance and upgrades of existing sites. Suppliers said they are being squeezed by rising oil and natural-gas prices  and surging demand following years of price and margin weakness. Also exerting price and supply pressure are the booming economies of Asia, particularly China,
which are absorbing major quantities of raw materials for coatings and other critical  commodities.

The price and supply dilemma was detailed extensively by number of representatives  of major suppliers of coatings raw materials, with some of the most pointed messages coming from The Dow Chemical Co.'s Pat Gottschalk, Global Business director, Solvents & Intermediates. During an interview with INSIDER NEWS, Gottschalk was bluntly outspoken on supply and price issues and what Dow Chemical sees as necessary to address the situation: higher prices to pay for maintenance and upgrading of production
Gottshcalk said key feedstock supply has become increasingly tight and costly, with  the price of propylene approximately doubling in 2004 alone. Coatings raw-materials suppliers have been forced to seek to pass the prices along. "We hope they understand, and realize what the implications are going forward," Gottschalk said. Prices have risen 30% to 50% for some oxygenated solvents such as isopropanol, MIBK and butyl Cellosolve, all of which are derived from propylene, he said.  Gottschalk
said major coatings companies have enjoyed strong earnings results over the past five years, while Dow's profits have declined sharply and remain below cyclic averages. The situation cost the company former CEO, Michael Parker, his job, and forced other major cost-containment actions. Addressing Dow's coatings customers, Gottschalk said: "We need to increase our pricing above costs to improve our margins and invest in and maintain our business. We have to have some good quarters, or we won't be
here to supply them (coatings makers), and then they will have a larger issue to deal with."

On a more positive note, Gottschalk said a point at which his company can justify  investment is not far from coming into view. "You pay us more, and we will ensure supply," he said, adding that Dow Chemical anticipates making announcements as early as mid-December about actions that will maintain or expand capacity.
"We need capital to invest in our facilities," he said. "We won't be in this business if  we can't get what's needed." He said coatings customers appear to have come to the realization that suppliers aren't singing the same old tune about price increases - that the situation is indeed urgent. A key, he said, is the message sent by Dow's recent move to announce price increases on a monthly basis. "It's clear there's an under-
standing of the seriousness of the issues, and an awareness of the importance of  investing in production. There has been an open discussion of the situation," he said.  Source: INSIDER NEWS (National Paint & Coatings Association and Paint & Coatings  Industry Magazine)

Asian Paints to change strategy
Coatings Flash - November 15, 2004

The global paints major Asian Paints Ltd is putting in place a new business strategy to generate additional revenues by licensing out its brands and technology. As part of a massive review of its global business, the company is taking a re-look at its operations across all its 29 plants, of which five are in India. It has now decided to exit markets which do not fit in with its strategy. The new business plan marks a major shift from the existing strategy of growing through acquisitions. "In an increasingly globalised economy, it is scale of operations and technological excellence that are going to give companies the competitive advantage. It is in this context that we have initiated the review. Wherever we find that the operations are not viable, we will exit," said Jalaj Dani, vice-president (international operations) of Asian Paints. Dani also said the company may not go for any more acquisitions at the moment.
Asian Paints has manufacturing facilities in Bangladesh, Mauritius, the Middle East, Nepal, Fiji, Tonga, Sri Lanka, Singapore, Hong Kong, Ningbo and Jamaica. Net sales from the company's international business was INR 4244.50 million (1 EUR = 58 INR) in 2003-04. The international business accounts for 19% of the total sales of the Asian Paints group. As per the new business strategy, Asian Paints will out-licence the brand name and the paint manufacturing technology. Recently, the company licenced out its brand and technology to PT Abadi, a leading paint company in Indonesia. Asian Paints also licensed its technology to Berger Paints, Pakistan. The company has already sold its Malta plant, which it had acquired from Berger Paints in 2002, to a local company called Vangeebee Ltd and also licenced out the Asian Paints brand name and technology know-how to Vangeebee. The company has also decided to shift its focus from China to six other emerging markets: Taiwan, Sri Lanka, Dubai, Egypt, Bangladesh and Malaysia. Dani said: "China is a very complex market. We want to restrict our product profile in China to only one segment - protective coating - and will focus mainly on Taiwan and other emerging markets."

Asian Paints to hike prices 5%
MUMBAI: A sharp escalation in raw material prices has triggered an increase in the price of paints after a gap of almost six years. Asian Paints, India’s largest paint-maker, has increased product prices by an average 5% with effect from December 1, ‘04.

The company is resorting to such a hike for the first time after 1998.

The prices of petrochemicals, which are the basic feedstocks for paints, have shot through the roof after crude oil prices vaulted to record levels recently.

Asian Paints, which resisted price hikes to cash in on the demand during the festive season, has now increased prices for most product categories. <more>

Paint industry thrives on real estate boom
M Abdur Rahim

Riding on success in real estate sector, Bangladesh's paint industry is witnessing enormous growth.
An official of Rehab (Real Estate and Housing Association of Bangladesh) said the paint industry is drawing local and foreign investments as the industry sees almost double-digit growth annually.

"Use of paint for both interior and exterior decoration is rising, giving a boost to the paint industry," said Ziaul Ahsan, executive committee member of Rehab.

Rehab sources said around 5,000-7,000 apartment units and 4,000-6,000 plots are handed over to buyers a year. Developers have so far handed over 70,000-80,000 apartment units to buyers in the last 20 years. With arrival of Asian Paints, India's largest paint manufacturer, Bangladesh has now become almost self-sufficient in paint. Officials of Asian Paints said annual demand growth at 7 percent prompts the company to make foray into Bangladesh market.

Asian Paints formed a joint venture with local company Confidence Cement in 2002 to set up a hi-tech plant at Gazipur with a capacity of 2,500 tonnes and initial investment of about Tk 15 crore.

Right from the beginning, Asian Paints aimed to pound the citadel of Berger Paints Bangladesh Ltd, which has long been dominating Bangladesh market with about 40 percent market share. <more>

Reichhold Announces Price Increases for All Coating Resins Sold in U.S. and Canada; Effective December 15, 2004
RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)--Nov. 11, 2004--Reichhold announced price increases today across all coating resin product lines sold in the US and Canada. Specific increases include $.05 per pound on all solvent-based coating resins as well as emulsion and dispersion chemistries, with the exception of epoxy resins and curing agents which will increase by $.08 - $.10 per pound. Polyester powder coating resins are also included and will increase by $.10 per pound while GMA acrylic powders are not affected. These increases are applied to both list and off-list prices and are effective for all U.S. and Canadian orders shipped on or after December 15, 2004.

"As industrial demand for coatings-related monomers continues to outstrip supply, especially in the area of acrylates, we are continually being hit with increases on these materials which are key in the production of our resins," explained Reichhold's Product Director for Global Coatings, Tony Rende. "This is only compounded by price hikes that we're seeing across other primary raw materials such as phthalic anhydride, xylene, TDI and linseed oil to name a few," continued Rende. "With crude oil and natural gas pricing hovering around record levels, it's evident that there is no immediate relief in sight for raw material or energy costs.

"While we are sensitive to the fact that we've had to announce more increases this year than in the past, we are simply responding to the burden that's being placed on us by current market conditions and, like anyone else in the supply chain, we have to maintain a profit to stay in business.

"We thank our customers for their business and continued support in these trying conditions and encourage them to contact their Reichhold sales representative if they have any questions regarding this price adjustment," concluded Rende.

HP, Epson present fade resistant dye-based ink-jet inks
While pigmented ink-jet inks have increasingly been used for better light and gas fade resistance of photographic prints, dye-based systems, still superior to pigments in terms of brilliance and colour gamut, apparently are on their way back up. Both Hewlett Packard and Seiko Epson presented fade resistance studies of their new generations of dye-based ink-jet ink systems during the NIP 20 Conference on Digital printing last week. While HPs new ink system was shown to be capable to achieve >100 years of predicted light fastness, Epson's new ink generation claims to feature up to 18 years of predicted ozone fastness on porous glossy photo paper - a vast improvement over the previous generation inks. More information on these developments, plus further highlighted reports from the NIP 20 can be found in a special issue of Jet-Age, the biweekly electronic newsletter focusing on ink-jet materials developments (http://coatings.de/jet-age).

A thriving Tipton powder coating firm today revealed it is creating more than 40 jobs as part of a £2.5 million expansion.
It is the latest boost in the town's fightback against a manufacturing slump that has seen hundreds of workers axed across the country. The news that Spectrum Architectural Coatings is planning to double its workforce comes on the back of the 100 new jobs announced with the opening of the new Hercunite Foundry.

Spectrum has triggered a huge expansion plan at the site in High Street, Princes End, which will include taking on a new storage depot, new machinery and workers. The company, which produces the powder coated aluminum frames for the construction industry, has already invested significantly over the past 18 months.

It has showcased its products all over the country after producing the powder coated aluminum frames for Chelsea football club's Stamford Bridge ground and Canary Wharf in London. <more>

Malaysian firms urged to take part in Hannover Fair to boost markets
MALAYSIAN companies can expand their export markets by participating at the world’s largest trade exhibition, the Hannover Fair, in Germany next year.The five-day fair, which starts on April 11, will cover 1 sq km, or 25 times bigger than all the exhibition halls in Putra World Trade Centre combined. A visitor needs to spend 1.8 days to visit all the booths.

The event will be jointly launched by German Chancellor Gerhard Schroeder and Russian President Vladimir Putin.

Federation of Malaysian Manufacturers (FMM) vice- president Datuk Francis Huang said Malaysia will be participating for the ninth time with a total of eight companies. “This is the perfect platform for Malaysian manufacturers to tap the enlarged European Union,” Huang told reporters at a briefing on Hannover in Wisma FMM in Kepong yesterday The FMM, which has 2,200 members, is the organiser for Malaysian companies interested in participating in the fair. A total of 200,000 visitors are expected to throng Hannover 2005, which will have 6,000 exhibitors from 70 countries covering over 200,000 sq m.
At the Hannover 2004 show seven months ago, there were 180,000 visitors and 5,040 exhibitors from 60 countries. Former Prime Minister Tun Dr Mahathir Mohamad was said to have spent three days at the fair. Malaysian companies need to fork out RM20,000 to lease a minimum space of 9 sq m. The space, however, will be subsidised by the FMM at a nominal rate. The Hannover fair is the world’s largest industrial technology exhibition. The top 10 participating countries include Italy, China, Switzerland, France, the UK, Spain, the US, the Netherlands and Turkey.

Eleven trade shows in eight halls will run concurrently at Hannover 2005 at a single central meeting place.Two new halls will be added, namely for the subcontracting and energy segment.

The sectors showcased include factory automation, motion drive and automation, digital factory, microtechnology, research and technology, energy, compressed air and vacuum technology, surface technology plus powder coating Europe, subcontracting and industrial service and equipment.

The event in the past managed to rope in as many as 12 Malaysian companies. The low participation is due to the misconception by manufacturers that participating in trade fairs is a one- off thing when in fact such efforts need to be continuous

  Powder Coating Manual -"The Powder Booth"------ (Part - 35)  
Recovery Systems
Powder booths utilize a fan assembly with a protective filter section and a containment vessel to pull air into the booth. This system, called a recovery system, captures the over sprayed powder for reuse or disposal. The recovery system provides the necessary containment and safety air, and recovers the over sprayed powder. Properly designed systems have a primary filter and a secondary filter, commonly referred to as the final filter. The first filter is used to separate the over  sprayed powder from the air for reclaim and the final filter is used to remove any particles that have passed through the primary filter, keeping the working environment free of powder particles. Commonly used recovery systems include the cyclone system, the filter belt booth, the cartridge module system, mini-cyclone systems and sometime systems that combine technologies in the same booth.

Cyclone Recovery Systems

The original powder booth was designed with a cyclone as the main component in the recovery system. The cyclone is used as a separator to classify powder by particle size. The larger particles are collected  in the cyclone for reuse and the super fine particles pass through the cyclone to the cartridge collector for scrap.

The overspray powder is drawn to the extraction duct of the booth by airflow from the recovery system fan pack. This airflow is generated by a blower that creates a vacuum in the booth through a ductwork system. The ductwork from the booth is connected to a cyclone, used as the  primary means of powder separation and recovery. The powder and air mixture enters the cyclone at a typical velocity of 60 feet per second (fps), and the cylindrical shape of the cyclone influences the powder/air mixture to turn centrifugally, with the powder particles dropping out to the reclaim canister located at the bottom of the cyclone. This reclaimed powder can be automatically transferred back to the feed hopper or the canister can be removed and dumped on a periodic basis. It is a good idea to put the recovered powder through a sieve to remove dirt .

The relatively clean air coming from the top of the cyclone is drawn into a cartridge collector or bag house for secondary separation. Depending on the powder and the cyclone design, 3 to 10% of the recovered powder is pulled past the cyclone to the collector. This powder is separated from the air by filters in the collector. The filters are back-pulsed periodically to dislodge the powder and drop it to the waste canister at the bottom of the collector. The clean air from the collector is blown back into the room through a final filter. The main advantage of this type of recovery system is the ability to spray an unlimited number of colors without the need for additional equipment. Overall material utilization is somewhat lower than cartridge module systems because some powder is separated out to waste. As mentioned before, this separation is related to powder particle size. The spinning in the cyclone takes the larger particles to the reclaim canister while the very fine particles (< 20 micron) are pulled through to the collector.

Cyclone Recovery System Although cyclone systems have the advantage of allowing the operator to run multiple colors without duplication of equipment, some of  the major manufacturers have not promoted them due to the safety regulations required for enclosed vessels. Safety dampers and explosion relief venting are required by NFPA. Also, the ductwork used to connect the components of the cyclone system may have traces of impact fused powder left after color change, creating a somewhat greater risk of cross contamination.

The traditional large-body cyclone system delivers an overall material utilization percentage that is less than cartridge module systems. The powder that is separated from the volume that is sprayed is typically  around 6 to 10%. When the recovered powder is sprayed the same loss occurs once again, reducing the overall material utilization by a further percentage. The overall material utilization must account for this cumulative loss. If first time transfer efficiency (FPTE) is very high the material utilization may be pretty good. If first pass transfer efficiency is poor the material utilization will be much lower.

The typical overall material utilization in a cyclone system ranges from 70 to 90%, compared to a cartridge module system which can deliver 90 to 97%.Recently, cyclone systems have been developed that use the same inertial separation technique as the traditional cyclone system with a different configuration that addresses some of the problems associated with the original systems. These systems are safer and more efficient and they still provide the ability to run multiple colors without dedicated collection equipment.

One such system uses a series of horizontally mounted cyclones. Over sprayed powder is drawn into the separators and removed from the fan air stream by centrifugal force. A pump at the end of each cyclone returns the powder to the feed hopper. The fan air is pulled through cartridges to ensure removal of any remaining particulate and  then it is discharged back into the room through a final filter. The small cyclones can be easily accessed and cleaned by opening the end, eliminating the risk of cross contamination.

Another of this new breed of mini-cyclone systems uses a series of small, vertically mounted cyclones. Each cyclone has a series of vanes mounted near the top that help to direct airflow in a downward spiral inside of the cyclones. An ”Autodamper“ system controls the airflow  through the unit by adjusting for system variables. The powder-laden air passes through the cyclones into the collection unit. From there it can be transferred back to the feed hopper or into another receptacle.  The air and a small volume of residual powder is carried on into the cartridge collector and discharged back into the building through a final filter.

This system can be color changed without the need for dedicated equipment. For additional flexibility, the cyclone unit can be disabled and the overspray carried directly to the cartridge module unit. This allows the operator to run short runs of various colors without contaminating the cyclones, providing faster color change times for  low volume runs and samples.
