APIL Industrial Paints Biz Revenue Falls In 2002-03 

Mumbai, July 3: Asian Paints India Ltd (APIL) has discontinued the production of automotive paints manufactured in technical collaboration with Nippon Paints Ltd of Japan. 

Instead, the company is catering to the automotive paints market exclusively through its joint venture (JV), Asian PPG Industries. 

The company’s annual report for 2002-03 states, “The transfer of powder coatings business to Asian Paints Industrial Coatings Ltd (APICL) and the discontinuation of Nippon automotive coatings have together resulted in the decline in revenue of industrial paints business of APIL. Excluding Nippon Paints’ automotive coatings and transferred powder coatings business, the sale of industrial coatings in 2002-03 would have grown by over 35 per cent over the previous year which is a healthy growth rate by any standard.”

Jenson & Nicholson Taps Judis Moneta For Biz Recast 

Mumbai, July 7: Jenson & Nicholson India Ltd has tied-up with Judis Moneta Financial Services Pte Ltd to restructure its operations and finances in an effort to revive the company from a bad financial spell. 

Jenson and Nicholson, a leading player in the Indian paint industry, has entered into an agreement with Judis Moneta for the operational and financial restructuring of the company in its entirety. <more>

When asked about these changes,  Mr. Bikash Mallick, Business Manager - Industrial Coating Division (South & West)Jenson & Nicholson (India) Ltd. informed  in his email to India Powder Coating,  "We will come back to you in due course with updated status" 

Earlier on June 18th the Economic times news story reported from Kolkata,

"The script is not yet ready but the smoke signals are getting easier to read. Financially crippled, Jenson & Nicholson (J&N), one of the country’s oldest paint companies, is looking for a suitor to bail it out. A reluctant prospect, Berger Paints conducted a due diligence but is unwilling to strike a deal.

Whenever you think of colour, think if us’. Maybe not. On Monday night, the company downed the shutters of its corporate office in the city. All 48 employees found themselves out of jobs and the top management remained untraceable. A notice signed by company managing director, JS Chatterjee, put up at the corporate office reads: “Tremendous financial crisis and losses are such that operations of the company are not economically viable.” Sources in Berger Paints acknowledged that PricewaterhouseCoopers (PwC) had been mandated to prepare a due diligence report on J&N as the first moves to buy out the company. “The financials of the company were dismal and its liabilities were too large. The chapter is now closed,” sources said"

DuPont Announces Launch of Coatings Ventures in China
[Insider News] July 21, 2003 Issue

DuPont Performance Coatings announced agreements with Beijing Red Lion Coatings Co. Ltd. of China forming two automotive coatings joint  ventures based in Beijing and Changchun, China. The ventures have  received final government approval and will be 60% owned by DuPont  and 40% by Red Lion. Operations area already under way, DuPont said.  Financial terms were not disclosed.

With the agreements, DuPont said it has increased its stake in an  existing joint venture by acquiring the interest previously held by  Akzo Nobel Coatings. In addition, DuPont has entered into a second  joint venture. The two businesses, both named "DuPont Red Lion," are  designed to modernize coatings production to support the Chinese  automotive industry with locally manufactured coatings and technical  service, DuPont said. The combined capacity of the two joint-venture  plants will start at 20,000 tons of paint per year, with production  supported by laboratories and application facilities located at both  sites. 

John R. Lewis, DuPont Performance Coatings Asia Growth Initiatives,  said the automotive market in China is recording the strongest growth  rates worldwide, with current annual production standing at about 1.2  million cars and 1.5 million commercial vehicles. "As one of the  fastest growing automotive markets in the world, China will play an  increasingly important role in our future business plans," Lewis  said. "Almost all international automotive manufacturers are planning  major investments to increase production in China, which already has exhibited stable, double-digit annual growth rates."

Lewis said a major share of the industry's growth will be generated  by the Chinese operations of DuPont's current global customers such  as Volkswagen, Ford Motor Co., General Motors Corp., Citroen,  Toyota ,and Nissan.

In Beijing, DuPont Red Lion will build a new production site for OEM  paints and an application center. Following completion, about mid- year 2004, production will be relocated to the site from an existing  plant in Beijing. The new plant will supply waterborne products to be  introduced in China in the near future, DuPont said.

The Changchun site in north China will be expanded and modernized at an incremental cost of $15 million. The Changchun joint venture was  originally established in 1995 by TOA International Co., Ltd. of Thailand and Changchun City Paint Factory as "TOA-CPF Paints Co. Ltd." Red Lion acquired the interest of Changchun City Paint in 2001, and DuPont is acquiring the interests of TOA in the previous venture.

Red Lion, founded in 1952, is one of China's largest coatings  producers, and manufactures a variety of coatings for the automotive,  machinery, sheet-steel, and building markets.

FDA clearances pursued for UV/EB Food Packaging
PR 3-07-03--Immediate Release: July 21, 2003

Chevy Chase, MD-Food packaging clearances for direct food contact using ultraviolet (UV) and electron beam (EB) materials such as coatings, inks and adhesives are being pursued by members of RadTech, the non profit trade association for the industry. "The fast growing and already wide use of UV and EB in the package converting industry is driving this initiative," according to David Diehl of PPG and President of RadTech. "While thermally cured solvent and water-borne systems have been used by the food packaging industry for many years, there are virtually no basic components that have been listed as yet by the FDA for the relatively recent strong emergence of UV and EB ink, adhesive, and coating formulations."

"Without FDA clearance, when UV and EB are used in food packaging, care must be taken to assure that there is a 'functional barrier' between the cured UV or EB formulation and the food," says Ron Golden of Surface Specialties, Inc. and RadTech Board member. "Consequently, although significant performance and productivity cost benefits are possible with UV and EB, end users have only limited ability to specify UV or EB materials in food packaging applications, such as inserts and game pieces for snack foods, lid materials, exterior of folding cartons, pouches for various types of seasonings and gravy mixes, and the like. Explicit FDA clearance would be a breakthrough to offer food packaging end users much broader access to all the significant advantages of functional UV and EB cured inks, coatings and adhesives." 

Nearly 50 RadTech members attended the first planning meeting for the initiative, with the group forming a new RadTech "FDA Food Packaging Alliance." The Law firm of Keller & Heckman, Washington D.C., has been retained to administer the initiative. For more information on joining the new alliance, please contact RadTech at, and visit

BASF Catalysis Award 2003 goes to Stefan Mecking
Coatings Flash - July 07, 2003

Chemist Dr. Stefan Mecking has received the BASF Catalysis Award 2003 from Dr. Stefan Marcinowski, member of BASF's Board of Executive Directors. The prize honors the 36-year-old researcher's outstanding contribution to the field of catalysis. "Catalysis is a field of research with enormous power to innovate and it's a key technology for meeting the challenges of the future. BASF therefore believes it is essential to support the work of young, talented researchers in this area," said Dr. Marcinowski, who is also BASF's Research Executive Director.
Dr. Mecking heads a team at the Material Research Center and Institute of Macromolecular Chemistry at the University of Freiburg, Germany. One aspect of his research is novel catalytic syntheses of polymer dispersions - aqueous slurries in which the polymer particles are so small that they do not separate out, even after a longer period.
"Catalytic syntheses can yield polymers and material properties that cannot be attained using traditional methods. Dispersions produced in this way are of interest in a variety of applications such as environmentally compatible and cost-effective UV-stable coatings," explained prizewinner Dr. Mecking. "I'm really delighted to win the BASF Catalysis award for my work - it's extremely motivating," he added.

Ferro Sells Petroleum Additives Unit, Completes Sale of Specialty Ceramics Business
[Insider News] July 14, 2003 Issue
Ferro Corp. announced the sale of its Petroleum Additives business to  Dover Chemicals, a subsidiary of ICC Chemicals Inc. The business  produces fuel additives and metalworking lubricants at a single  operating facility in Hammond, IN. Sales for the business were  approximately $32 million in 2002.

Ortino said the divestitures follow a "period of  significant investment in acquisitions" and reflect "our continued  efforts to reposition and improve the growth profile of Ferro's  portfolio." He said the company is focusing on the expansion of  businesses that "can attain critical mass, have global scope and that  either have or can develop sustainable competitive advantages." 

Ferro is a manufacturer of performance materials, including coatings 
and specialty chemicals.

This is coupled with capital investments in plant and equipment, processes, research and development.."

USA: Architectural coatings follow changing building trends
Coatings Flash - July 14, 2003

Changes in the materials used in the US housing markets are impacting on the types of coatings being used. In 1991, 45 % of all new home exteriors were built of wood, by 2001, this proportion had dropped to 15 %. Building materials in the last decade have diversified into brick, stucco, aluminium, cement, fibreboard, hardboard, drywall and even steel.
While 100 % acrylic was the perfect match for painting wood, it is suggested that this may not necessarily hold true for other materials. Indeed in Europe and Asia, where wood is less prevalent, 100 % acrylic latex paints, rely heavily on vinyl versatate an styrene acrylics for exterior house paints. Formulators in North America are therefore beginning to blend acrylics with other systems to achieve the right mix for specific applications, for instance copolymerising versatate binders with acrylates or vinyl acetate. 

Eisenhower's Light Industrial Facility Saves Navy $2 Million
Moderator: With the permission from Stephanie Collins, Editor, Navy NewsStand 

By Journalist Seaman Michael Perez, USS Dwight D. Eisnehower Public Affairs

NEWPORT NEWS, Va. (NNS) -- A thousand dollars here, a thousand dollars there. Who cares? The crew of USS Dwight D. Eisenhower (CVN 69) cares.

Ike's aircraft intermediate maintenance department (AIMD) is fortunate enough to have access to a facility known as the Light Industrial Facility (LIFAC). LIFAC is a building where Ike Sailors fabricate and restore materials for the aircraft carrier. Among the items they refabricate are ready room chairs, watertight and non-watertight doors. They also create new items, such as funnels and M-60 mount covers.

“We are the first carrier to do refabrication on watertight doors,” said Aviation Maintenance Administrationman 1st Class (AW/SW) Charles R. Dovich, LIFAC production leading petty officer. “We are also the first carrier to create M-60 [machine gun] mount covers.”

At LIFAC, a new process for ships known as 'powder coating' is being conducted as an alternative to painting. Powder coating is very unique in that it lasts ten times longer than regular paint, won’t rust, is environmentally safer, is an easier process and takes less time to complete a project.

“The powder coating costs about the same amount as regular paint, but since it lasts longer, it saves money in the long run,” said Aviation Structural Mechanic 1st Class (AW) Michael L. Glass, LIFAC production supervisor.

As proof the powder coating is a reliable process, AIMD has left a powder-coated door outdoors for more than one-and-a-half years now. The door has borne the weather and is still in great condition, according to Glass.

Powder coating is just one of many stations LIFAC utilizes. Included is the fabrication bay, where Sailors measure, cut and create new items for the ship. Attached to that are the wielding stations, where watertight doors and other items are currently being worked on. Then there is the upholstery shop, where the fabric is redone on ready room chairs and M-60 mount covers are sown. Next, there is the blast booth, where doors and other materials are sandblasted down to bare metal. Finally, there is an area where some regular painting on items, such as non-watertight doors, occurs.

It's with these stations that AIMD is able to do a lot of different jobs to save the Navy as much money as possible.

Since AIMD took over LIFAC in May 2001, they've saved the Navy in excess of $2 million dollars, according to Dovich. They've refabricated 300 chairs, 1,000 non-watertight doors, 200 watertight doors, 39 communication booths and numerous other items, such as firefighting hose reels. They've also constructed 600 funnels, which are important for reactor department’s shore steaming operations.

“We have a lot of hard-working Sailors here,” said Dovich. “I would put this work force against any work force in the Navy.”

With all the hard work they put in, LIFAC just wants Ike to know that they are here to support the crew. They feel strongly about coming out of the yards on time.

“We feel good knowing that we are doing our job to support the ship,” said Aviation Maintenance Administrationman Senior Chief (AW/SW) Dave L. Harris, LIFAC leading chief petty officer. “Life is good here at LIFAC.”

Oven fire at furniture manufacturer results in smoke and water damage 
Moderator: With permission from Rich Martin, managing editor,  of  The Roanoke Times 201 W. Campbell Ave., P.O. Box 2491, Roanoke, Va. 24010-2491, Main Switchboard: (800) 346-1234. 

A furniture manufacturing company in downtown Roanoke was damaged by heavy smoke and water Wednesday after a fire broke out in its giant oven.

Shop supervisor Marty Neal said there were several pallets of powder coating in the oven that were being baked to dispose of them. The coating is a paint that goes on metal furniture in powder form and is then fired in the oven to set it. "I could see when the blowers kicked off there was smoke coming out" of the oven, said Neal. The oven is about twice the size of a large walk-in freezer.

  Powder Coater’s Manual ------- (Part - 17)  
  Titrations and Alkalinity

Titration must be performed regularly, even for operations that use automatic chemical addition pumps. The items that are routinely read include free alkalinity, total alkalinity, relative alkalinity, total acid, and acid consumed.

The pH scale is logarithmic and the intervals are exponential. 
pH = -log [H+].

Free alkalinity is the active alkalinity, which supplies the power for cleaning. It is the range from the operating pH of the bath to pH = 8.3. It is used to control concentration.

Free alkalinity is found by titration of a 100 ml sample volume with an acid titrant of 1.0 normality using phenolphthalein (P-12) indicator. The color change is from pink to clear. The number of mls. Of titrant required to reach the endpoint is the free alkalinity value in points (1 ml = 1pt.). By equating points of free alkalinity to concentration all alkaline cleaners can be controlled by free alkalinity points. Total alkalinity is the range from the operating pH of the bath to pH = 3.5.
Operating pH 3.5 7.0
Total alkalinity is found by taking a 100 ml sample and adding indicator ”E“. Titrate the sample with solution No1 until color changes from blue to green. The number of mls. required to reach the endpoint is the total alkalinity value in points (1 ml = 1pt.).
Relative alkalinity is defined as: 
[Free alk. ( FA)/ Total alk. (TA)] x [10,000/ Y]
where Y = pre-determined factor which will vary from product to product.

For a fresh bath the relative alkalinity will always equal 100. When the relative alkalinity reaches 60 it may be time to dump and recharge the bath.

Y = 50

Initial Charge –

FA = 5 pts.
TA = 10 pts.

Relative Alkalinity = [5/10] x[10,000/50] = 100

After 3 months –
FA = 5 pts.
TA = 18 pts.
5 10,000
Relative Alkalinity = [5/18] x [10,000/50] = 55

This calculation does not consider depletion of chelates, sequestrants or surfactants, only alkalinity.

Phosphate Stage - A standard for the coating weight should be established and routinely monitored. The proper chemical concentration, pH (or acidity level) and temperature should be established at the start of the shift, the middle of the shift, and the end of the shift, to maintain the balance necessary to provide the desired coating weight. Because all phosphate products and vendors have there own unique blends, be sure to follow the guidelines provided by your chemical supplier and maintain the bath at their recommended concentrations to achieve optimum results. 
Total Acid – Phosphatizing Solutions
Total acid is defined as the range from the operating pH of the bath to pH = 8.3. Total acidity can be used to control the concentration of the phosphatizing chemicals in the bath.
Operating pH 8.3 7.0

Total Acid
Total acid is found by taking a 100 ml sample and adding indicator P- 12. Titrate the sample with solution No2 until a light pink color appears. The number of mls. required to reach the endpoint is the total acid value in pints (1 ml = 1 pt).

Acid Consumed
Acid consumed is the range from the operating pH of the acid bath to pH =3.5.
3.5 4.5 (Operating pH) Acid Consumed Acid consumed is found by taking a 100 ml sample and adding indicator ”E“. Titrate the sample with solution No1 until the color changes
from blue to green. The number of mls. required to reach the endpoint is the acid consumed value in points (1 ml = 1 pt.). The points of acid consumed can then be equated to pH values and used to control the pH of phosphatizing baths. As the points of acid consumed increases
so does the pH. (i.e. as the pH rises so will the amount of solution
No1 needed to reach the endpoint).

• Seal Rinse - Like tap water rinses, the variables to be controlled are pH and conductivity. The chemical vendor dictates the standard for pH level and the standard for conductivity level is the raw water plus any additional conductivity added by the seal rinse solution. These variables should be monitored along with the other rinses, three times a day.

• DI Rinse - The conductivity of the DI water should be monitored to be sure that it conforms to the standards earlier mentioned, 50 micromhos for recirculated DI water and 10 micromhos for fresh. 

Manufacturer guidelines should be followed for maintenance of the DI generation system.

The more carefully a pretreatment system is monitored and adjusted, the more consistent the results. Many finishing systems have some automatic monitoring and adjustment systems. This could be as simple as timed metering pumps or it could be as complex as complete PLC control. Automated addition of alkaline cleaning chemicals can often be achieved through feed equipment monitoring solution conductivity. While automated addition of chemicals is better from the
standpoint of process control, the automatic controls must be checked to be sure that they are performing properly. There is no substitute for regular titration.
