To ensure good adhesion over a bare plastic substrate requires that it be cleaned properly and coated with adhesion promoter before application of an undercoat. This standard operating procedure (SOP) covers using PPG’s VOC compliant system for preparing unprimed plastic.
Follow along with the outlined process below to learn how to properly prepare plastic parts for a repair.
NOTE: It is best practice for the highest level of integrity to use basecoat activator in solvent basecoat, especially for leading-edge parts and fascias.
NOTE: It is best practice for the highest level of integrity to use Adjuster and Modifier in waterborne basecoat, especially for leading-edge parts and fascias.
NOTE: Adhesion promoter must be sealed before topcoating with waterborne basecoat.
To maximize coating flexibility and chip resistance, follow product instructions for use of the flexible additive in the undercoat and clearcoat. Not all undercoats or clearcoats require a flexible additive due to their flexibility properties. Use an activator in the basecoat. Refer to all product bulletins for detailed instructions.
Proper cleaning of the vehicle is the first step for any repair. This standard operating procedure (SOP) covers preparing the surface and removing dust and contaminants from the vehicle to ensure a defect-free finish.
The steps in this standard operating procedure will show how to prep bare plastic for repair using PPG products for National Rules areas.
