DK 400 Solvent-Based

DK 400™ is a 2 component 51% solids, solvent acrylic aliphatic polyurethane designed as a non-yellowing clear coating for interior concrete, cement based overlays, or as a top finish coat on epoxy systems. The high performance clear top coat generates the premier balance of strength, added UV stability, flexibility, chemical and scratch resistance that is both user-friendly and extremely durable. As a vertical wall coating, it enhances anti-graffiti properties. DK 400 is ideally suited
for both commercial and residential settings: aircraft hangars, clean room floors, manufacturing facilities, warehouses, bars, clubs, retail stores, automotive showrooms, residential interiors, garage floors, stadiums, or any high traffic area where an exceedingly resilient floor is desired.
