![]() For these reasons automotive paint manufacturers heavily feature polyurethane as clear coat’s main component. After the base coat layer has sufficiently set up, the protective clear coat is sprayed (layered) on top for protection.Īutomotive clear coat must be resilient, durable, and highly flexible to meet the complex and ever evolving needs of automobiles. When the base coat’s solvents dry (aka curing or outgassing) the pigmentation, suspended within the resin, is left behind on the surface. The resins are most often composed of either a solvent-based polyurethane or a ‘water-based’ acrylic. The vast majority of modern automotive paint systems utilize chemical or ‘water based’ solvent carriers to both disperse and adhere the base coat pigmentation (solid color pieces) to vehicle panels.Ĭolor pigmentation, and/or optional metallic flakes or pearlescent crystals, are suspended within a resin that binds to vehicle panels.
