Purpose/Material Description.

Basecoat (BC) components of these systems are typically one-component (solvent) acrylic/melamine. Clearcoat (CC) components of these systems are one-component (solvent) carbamate or similar technologies. Typical volume solids as sprayed are typically 35% to 50% for BCs and 45% to 60% for CCs. Each combination of specific BC and CC must be tested and approved as a BC/CC system. The individual components are not interchangeable and are approved for use only with combinations of BC/CC of the total paint system which was used in the qualification testing. It must also be compatible with specific adhesion promoters and/or primers used with specific plastics.
