GM has approved several of PPG's automotive coatings.
A new line of PPG and Nexa Autocolor brand low-VOC automotive refinish clears, primers and sealers has received North American approval by General Motors for warranty repairs on its vehicles. The products are designed for use with Envirobase High Performance or Nexa Autocolor brand Aquabase Plus waterborne basecoats. Each product meets GM's rigorous quality standard known in the industry as Specification GMW15406. The approvals cover product lines including PPG's EC700 series clears, ECP10 series primers and ECS20/ECS60 series sealers. Also approved are Nexa Autocolor brand P190-6759/6790 clears, P565-314x/312x sealers and P565-540x primers. Intended as one-visit clears, EC700 series and Nexa Autocolor brand P190-6759/6790 coatings eliminate the long flash times between coats, reducing cycle time with no compromise in the quality or appearance required by high-production shops. PPG's D8113 matte clearcoat has also earned GM approval. Instead of using a flattening agent to achieve low gloss with existing clears, D8113 was formulated as a matte finish to help automotive manufacturers meet the growing trend.
