Acrylic polyurethane clear coat is widely used in automotive refinishing where gloss retention, durability, and smooth film formation are required. SW990 High Gloss Clear Coat is a two component coating designed for professional vehicle paint repair.
After curing, the coating forms a transparent protective layer that enhances the depth and brightness of the base color. It can be applied over single stage basecoat systems and allows efficient polishing during finishing operations.
This product is commonly supplied to body repair shops, paint distributors, and automotive refinishing suppliers who require stable performance and consistent application behavior.
The coating produces a bright and transparent surface layer that improves the visual depth of the base color while delivering a clean reflective appearance.
Balanced viscosity and solvent system allow the paint to level evenly during spraying, helping reduce orange peel and improving surface uniformity.
The cured film provides resistance to fuel exposure, cleaning chemicals, and environmental contaminants encountered during vehicle operation.
The acrylic polyurethane resin system maintains gloss and clarity over time, reducing yellowing and surface dulling.

It can be applied over two stage basecoat systems or properly prepared old paint surfaces.
