e-Commerce Highlights And Asian Adoption

(John Everett Product Marketing bannerGiven the immense geography of the coatings industry across the Asia Pacific region it is not surprising that tool to enhance communication and commerce are watched closely. Indeed, new web sites allow consumers to get anything and everything delivered right to their front door; groceries, medicine, and even — epoxies! Many people, however, still harbor under the common misapprehension that all Web sites are floundering economically and nearing extinction, when that is far from the whole truth. While many Web sites have failed, there are still those that are not only surviving, but thriving. is a well know example of a site that attracts a lot of attention from Asian sellers and buyers looking to trade chemicals. Extranets, such as Dow Chemical's MyAccount@Dow are providing a host of sophisticated functions on a 24 / 7 basis, regardless of time zone constraints.

What separates the successful dot-coms from all the dot bombs? The key to success in the virtual market place is not by erasing the traditional procurement methods, but rather by supplementing those existing procurement channels and adding alternative levels of service, something beyond the traditional venues. Chief Executives, Chief Information Officers and e-business leaders are learning from past failures, and realizing that a winning website may just be the edge their company needs to succeed in the flailing global economy of today. These new e-commerce initiatives, however, must compliment, and not compete, with a company’s existing business., the first-ever Web site designed exclusively for the sale of epoxy resins and related products, is a Web site that is not trying to take business away from other procurement venues, but rather seeking to add an easier way to generate more business., is, unlike many new business initiatives, and in particular e-businesses begun in the past two years, a success. has, since its launch in late January 2001, surpassed sales goals and reached profitability within the first year after its launch. The straightforward business rules of establish the site as a channel for formulators of epoxy coatings to easily and quickly purchase epoxies and related products without developing a long-term relationship with the supplier. Customers looking for a set amount of product in a convenient, one-stop shop can use while customers seeking a wide range of services and purchasing options can benefit more from a traditional sales force. All business units succeed. A similar approach has been followed with the launch of from the Dow Corning Corporation. Customers wishing to receive the full and world class service of Dow Corning are encouraged to continue to purchase via the associated representative. Those seeking the lowest price on standard silicone products and no service are directed to the web business. is designed for those that can work with straightforward business rules, such as ordering in full and half load quantities, a fixed payment term and penalties for order changes and cancellations. The site not only accepts orders for delivery in North America and Europe but also the Middle East, Japan, Korea, Taiwan and Southeast Asia. Prices are listed in U.S. dollars, Euro and Yen. John Everett, Global Site Leader for says "we are delighted with the response we have received from the Asia Pacific market to our e-commerce site. On a daily basis customer are placing orders with us, contacting us on order status and pricing opportunities as well as challenging us to expand and provide a broader range of complimentary products." Since the approach levers-off Dow Chemical's establish product and logistics position in Asia, customers are assured of getting the quality product they want in a reliable time frame. "We are often asked who buys from" says Everett. "Basically our accounts span the classical users of epoxies resins, i.e. coatings, composites, electrical, adhesives, etc, but more principally from those accounts wishing to explore this new purchasing approach and efficiently obtain standard raw materials. So far, all of our customers in Asia have been new business for Dow's epoxy division."

Asian Paints to set up unit in Pondicherry
Business Standard, January 30, 2003

Asian Paints India has informed the Bombay Stock Exchange that it has decided to set up a plant at Pondicherry, subject to necessary approvals and licences.

The proposed greenfield unit is to have a capacity of one lakh tonne per annum, and would be its largest.

The board has also approved the merger of Pentasia Investments, a wholly owned subsidiary, with itself. The proposed merger is subject to the approval of the shareholders of the company and requisite approvals.

Ashwin Dani, vice chairman & managing director, Asian Paints (India) said in a press release, “The proposed plant became imperative owing to the good growth rates witnessed by the company in the last couple of years. The last manufacturing facility set up by the company was in 1989 and the company has done an excellent job in last couple of years to further sweat the assets as well as increase productivity and capacity at existing plants.”

“Also all water based products especially emulsions have witnessed very good growth rates, which has further strained capacity at the existing facilities for these products,” he added.

The plant at Pondicherry will be scaled to its full capacity over a period of time and the investment in the mentioned project will also be made in a phased manner, the company said.

At present the company has four manufacturing units: at Bhandup in Mumbai, at Kasna and Patancheru both in UP and at Ankaleshwar in Gujarat. Asian Paints’ present combined capacity of the existing four plants in India is 230,900 tones per annum.

The company has recently picked up 50.1 per cent stake in the Singapore based Berger International for a consideration of Rs 57.6 crores. This was followed by its takeover of management control of the Egiptian Paint major SCIB Chemicals for around Rs 24.5 crores.

In November 2001, the paint major acquired the powder coating business of Howcoplast Chemicals for Rs 16 crores.

Net loss for PPG Industries
(European Coatings Flash - January 27, 2003)

For all of 2002, PPG Industries recorded a net loss of USD 69 million, including one-time aftertax charges. Excluding these items, net income was USD 476 million. Sales were USD 8.1 billion. Net income for 2001 was USD 387 million, including a USD 71 million aftertax restructuring charge. Excluding the charge, income was USD 458 million. Sales were USD 8.2 billion. "We expect the global economic environment to be challenging once again in 2003," said Raymond W. LeBoeuf, PPG chairman and chief executive officer. "Nevertheless, we remain committed to further improvements in our cost structure and cash flow. Last year we lowered manufacturing and overhead costs by about USD 140 million, reduced debt by more than USD 400 million and increased our dividend payments for the 31st consecutive year. We expect another year of strong cash flow in 2003, which will allow us to reduce debt and increase our financial flexibility."
For all of 2002, coatings-segment operating income was USD 605 million, up 22 % from 2001. Coatings-segment sales for the year rose 1.6%, to USD 4.482 billion.

(European Coatings Flash - January 27, 2003)

The Degussa (China) Holding in Beijing was inaugurated on Monday, the 20th of January 2003. In future, all Degussa companies in China are to become subsidiaries of Degussa (China) Holding, whereby it is planned to transfer all the stakes currently held by Degussa AG or other Group companies in China-based companies to the holding within the near future. Moreover, the holding is to undertake all of Degussa's new Chinese-related investments. Degussa aims to significantly increase its involvement in China over the next few years. A few weeks ago, basic planning was started on a Degussa "multi-user production location", in which infrastructure is to be shared by several business units to achieve a better cost and utilities situation. In the view of Prof. Utz-Hellmuth Felcht, Management Board Chairman of Degussa AG, Dusseldorf, Germany, the Chinese specialty chemicals sector will take second place behind the European Union in global rankings by 2008. Also work began on constructing a Degussa R&D center in Shanghai this January. The investment volume for the R&D center, which is scheduled to take up operation at the end of 2003, amounts to some ? 10 million.

NZ company develops new powder-coating process for wood, achieves first export contract
New Zealand City Ltd,20 January 2003 ( )

A New Zealand company has sealed its first export contract for its revolutionary method of colour-coating wood products.Climate Coating Ltd now has a million-dollar Australian export trial for the new product, a powder-coating process for wood products used in the building, commercial and residential furniture, cabinetry and joinery industries, and outdoor products.

The new finishing solution involves applying a fine dry powder onto engineered wood products such as medium density fibreboard and plywood.The product has the functionality and durability of a laminate, making it an ideal finish on wood.

Until now, the difficulty in coating non-conductive base materials has been a barrier to extending the process which is already in common usage with metals. . The Climate Coating company is a graduate of the Carter Holt Harvey Ideas to Business programme.

It has also been nurtured and supported through almost three years of research and development, assisted with a $100,000 investment from Technology New Zealand. The Australian export deal comes after a 10-month period of testing and marketing trials, tweaking and correcting the product.

The company is now also eyeing the Asian and US markets.

Jotun Paints acquires Omnifire
(European Coatings Flash - January 20, 2003)

Jotun Paints (Europe) Ltd has purchased Omnifire (UK) Ltd along with all its technology on thin film intumescent coatings for steel, manufacturing and worldwide distribution rights (with the exclusion of North America) in December 2002. Since 1999, Jotun Paints - then Jotun-Henry Clark Ltd - has been manufacturing "Steelmaster" products at its Flixborough factory. This followed a business alliance between the two companies which also resulted in Jotun's marketing of Omnifire's intumescent coatings, its complementary topcoats, and its fire-engineering expertise. Steelmaster products have used on projects like the airport of Hong Kong. The Jotun purchase of the Omnifire technology is effective as from 1st November 2002, after which time Omnifire ceases to exist.

Pacer Technology's Super Glue subsidiary has launched a line of epoxy adhesives aimed at the automotive, marine, plumbing, pool and spa, and sports markets. Anchor-Tite is a two-part industrial strength adhesive for use on metal, plastic and rubber with a new feature for consumer epoxy adhesives of having the ability of working in contact with water.

Eastman has launched two new adhesion promoters for the automotive paint-on- plastic market. Both the chlorinated and non chlorinated versions are designed to be the active component in adhesion promoter primers for colour coats and topcoats with polypropylene and thermoplastic olefin substrates. (Chem Week, 13 Nov 2002, 164 (45), 32)

the Swedish Institute for Surface Chemistry, is planning a two-year project with the aim of improving the application of powder coatings to MDF. A particular problem exists with edge coverage. The reasons for this are not fully understood, but Dr Larsson of YKI believes that the surface properties and conductivity of the MDF are implicated. The project is obviously relevant to both thermal and UV-cured powders. YKI is looking for companies to join the research consortium running and financing this project.

  Powder Coater’s Manual ------- (Part - 12)  
Zinc Phosphate

Zinc phosphate is a non-metallic, crystalline coating that chemically adheres to the substrate. Zinc coatings are extremely adherent, they provide a uniform coating with improved coating adhesion properties, better coating in recessed areas and better corrosion resistance.

A typical zinc phosphate consists of:

• phosphoric acid base
• accelerators
• zinc salts

Zinc phosphate comes from the solution itself, not from the part surface like an iron phosphate coating. Crystals begin forming at anodic sites on the part surface and stop forming when they hit another crystal. The more origination sites the better the density of the coating. For powder coating, it is best to keep the and densely packed. Powder does not stay in the flow stage for very long. Larger phosphate crystals may not allow the powder material to completely wet
the surface and a capillary layer may form under the coating. Moisture will penetrate the coating and cause corrosion that will lift the coating from the surface.

Unlike the iron phosphate, a zinc phosphate can not clean and coat simultaneously in a three-stage process, a separate cleaning stage is required.

Activating (Prior to Zinc Phosphate)

When zinc phosphating, the metal surface is activated by an additive in the cleaner bath or in a conditioning rinse prior to phosphating. Conditioners are mild alkaline suspensions of specialized active titanium salts that adhere to steel, zinc and aluminum surfaces. The conditioner will set up a network of uniform acceptor sites for zinc crystals to deposit. This will increase the number of zinc phosphate crystals, decrease the size of these crystals and generally improve the quality of the zinc phosphate coating. The small crystal size will be more
uniform and lower weight, helping to promote adhesion, control the cost of phosphating, and generating less sludge.

The crystal size of the phosphate coating has an impact on paint bonding capacity and corrosion resistance. A large crystal structure is more porous, has poorer corrosion resistance, and requires more paint to achieve a complete film. A fine-grained, tight, uniform coating will
provide the best performance. The conditioner in the rinse preceding the phosphate stage can assist the development of this fine-grained phosphate coating.

Adding oxidants such as nitrate, chlorate, or nitrite controls the rate of coating formation. The proportion of these various ingredients can control the coating weight and phosphate crystal size. Fluorides are added if aluminum must be processed.

The reactions at the surface of the part during phosphating are:

1. Pickling attack on the metal and oxidation of hydrogen to water
2. Increase of the pH at the interface of the metal and the phosphate solution
3. Over-saturation of the film with coat forming substances
4. Nucleation on the metal
5. Growth of phosphate coating
6. Oxidation and precipitation of iron as sludge

The composition of the bath, the temperature, exposure time and the previous cleaning process will affect the phosphate composition and crystalline phase.

Zinc and polycrystalline phosphate solutions do require more careful attention to produce consistent high quality results. Additions of zinc phosphate and nitrite accelerator to the bath to maintain the proper concentration should be made by automatic feed pumps to ensure good quality and minimum chemical consumption. The improper concentration of these materials that results from bulk adds will produce coatings that are soft, too heavy, and create excessive sludge. If the materials are allowed to run too low, the coating will be coarse and spotty, resulting in poor adhesion and corrosion resistance.

Like other pretreatment processes, time temperature and concentration (total acid, free acid, accelerator and fluoride) will affect the outcome.

Zinc phosphate is the preferred conversion coating used by the automobile industry because of the superior corrosion resistance. The coating is firmly attached to the metal by ionic bonding, the porous crystalline structure provides an extended surface for paint bonding, and if the paint surface is scratched, the inorganic coating protects against corrosion "creepage."

A zinc phosphate solution will continually produce sludge through oxidation of soluble iron to an insoluble state that precipitates. A sludge removal system must be used to provide constant removal of this sludge. The rinse stage following the phosphate should be ambient tap water. Phosphate salts are more soluble in cold water. The overflow volume should be sufficient to keep the rinse clean and reasonably cool. Comparison of Iron Phosphate to Zinc Phosphate

From an environmental standpoint, iron phosphate is preferred because it does not generate large quantities of heavy metals that require waste treatment. In some municipalities, an iron phosphate solution can be neutralized and released to drain. Some coaters have waste treatment for iron phosphate and many coating facilities choose to have it waste hauled by a licensed hauler.

Zinc is listed by the United States Environmental Protection Agency (USEPA) in the Resource Recovery and Reclamation Act (RCRA) as a hazardous substance that is subject to waste regulations. It must be treated prior to discharge and the sludge must be waste hauled.In terms of performance, zinc phosphate with a chrome sealer will typically provide far superior corrosion resistance. Iron phosphate is satisfactory for almost all indoor applications where corrosion resistance is not critical. Zinc is required for outdoor product with superior corrosion resistance requirements. Almost all automotive-specifications call for zinc phosphate.

When deciding between zinc and iron phosphate, the end use of the product is the most important factor. For indoor use in non-corrosive environments, iron will work well and it has several economic and environmental advantages. Zinc will provide the undercoat protection needed for the more demanding product used outdoors or in highly corrosive environments. The quality of the cleaner and the finish coat must also be considered. Part of the attraction of powder coating is the durability of the film. Good cleaning and high quality powder may allow the use of a less resistant conversion coating.
