DK 400WB™ is a 2 component 57% solids, water based acrylic polyurethane designed as a non-yellowing clear coating for concrete, cement based overlays, or as a top finish coat on epoxy systems. The high performance clear top coat, available in gloss or satin finish, provides the durability of a solvent base system with the ease and safety of a low VOC (73 g/L) water base system. Unlike nearly all polyurethanes, DK 400WB has remarkable properties related to vapor permeability that permit its use in an exterior setting.
Note: See paragraph 5 under Sureface Prep. Generating the premier balance of strength, added UV stability, flexibility, chemical and scratch resistance, it is both user-friendly and extremely durable.

As a vertical wall coating, it enhances anti-graffiti properties. DK 400WB 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.
