PPG figures in new launches

PPG’s global headquarters in Pittsburgh, USA

PPG Industries has launched new products for the automotives and building products sector and had its coatings systems qualified for use by aircraft maker Airbus.

The Pittsburgh (US)-based company’s automotive refinish business announced that Deltron DPS3105 V-Prime Quick Prime Ure-thane Surfacer, a gray speed primer designed for spot and panel repairs, is now available. The new primer surfacer offers outstand-ing film build, fast dry-to-sand times and excellent resistance to film shrinkage.

“DPS3105 is a valuable addition to the Deltron brand,” said Jennifer Boros, PPG marketing director, collision segment. “It provides PPG customers with fast air-dry performance for excellent cycle-time efficiency with high-quality results. Production-focused colli-sion centres carrying out premium-level refinish work will appreciate this new product’s capabilities.”

According to Boros, DPS3105 features dry-to-sand times of as little as 30 minutes and a high film build of 2.0-2.5 dry mils per coat. The primer is easy to apply and sand. It is rollable, can be wet-sanded, and enables direct application of a basecoat. DPS3105 can be used with Deltron DCX3030 Hardener and the new DCX3035 High Temperature Hardener.

The company’s coil and building products group has introduced Duraform BP coating, a next-generation polyester coil coating en-gineered specifically for building product manufacturers.

Designed for one-coat application over aluminum or two-coat application over aluminum or hot-dipped galvanised steel, Dura-form BP coating is formulated with PPG’s proprietary star-shaped polyester polymer to enhance forming flexibility and increase resistance to colour fading, chalk, dirt and stains.

The coating is available in a wide palette of colours in high, medium and low glosses, and it offers more processing flexibility than conventional polyester coatings because of its wide cure parameters and excel-lent flow characteristics.

Brian Knapp, PPG director, coil and building products, said Duraform BP coating is formulated to deliver a higher grade of coating quality to value-driven building product manufacturers. “The unique chemical structure of Duraform BP coating enables it to outper-form traditional polyester coatings, particularly through its bonding strength with aluminum and galvanised steel,” he said. “That enables our customers to make products that look better and last longer at an economical price.”

AEROSPACE APPLICATIONS

Meanwhile, PPG aerospace coatings group’s basecoat-clearcoat exterior topcoat systems, which have been qualified at Airbus, offer appearance, production, operating and maintenance benefits.

High-solids Desothane HD/CA 9008 basecoat-clearcoat has been qualified for application as a topcoat system as well as with chro-mate-free Desoptime CF/CA 7049 primer that Airbus has long used. Also qualified is the basecoat-clearcoat selectively strippable system with chromate-free F565 intermediate coat applied over the primer that facilitates repainting without removal of the primer.

Desothane HD/CA 9008 basecoat-clearcoat consists of a heavily pigmented basecoat that provides colour with less paint than con-ventional high-solids paints and a clearcoat that extends service life, improves buffability and achieves a smoother, high-gloss sur-face that is easier to clean.

PPG basecoat-clearcoat systems provide superior aesthetics, while weight savings improve fuel economy and the enhanced colour and gloss retention helps reduce maintenance to benefit airlines, according to Dirk Thelen, PPG key account director for Airbus pro-grammes and business manager, EMEA (Europe, Middle East and Africa) south region.

“We worked closely with Airbus to demonstrate the productivity and appearance advantages of the PPG basecoat-clearcoat sys-tem,” Thelen said. “Airbus wanted to offer its customers advanced coatings technology that many airlines already use in their own maintenance operations. For airlines, having Airbus use the same coatings system on new aircraft that they use in maintenance is a significant benefit.”

In the selectively strippable coatings system with PPG basecoat-clearcoat, F565 intermediate coating is applied over the primer, and the basecoat-clearcoat and intermediate coating are easily removed during repainting, leaving the primer intact. Desothane HD/CA 9008 basecoat-clearcoat and Desothane HD/CA 9008 ultraviolet-resistant external clearcoat also are qualified independently at Air-bus.

QUALITY MARKS

Desothane HD/CA 9008 basecoat-clearcoat topcoat system used with or without Desoprime CF/CA 7049 primer as well as the selec-tively strippable basecoat-clearcoat system are qualified to AIMS 04-04-025, AIMS 04-04-033 and AIMS 04-04-037. Desothane HD/CA 9008 clearcoat is qualified to AIMS 04-04-023 for independent application.

Desothane HD/CA 9008 basecoat-clearcoat is also part of a growing number of PPG Aerospace chromate-free systems qualified to SAE International’s Aerospace Material Specification 3095A for airline exterior paint. Nearly 250 aircraft have been successfully painted with PPG basecoat-clearcoat systems.
