UL FR-263

Fire Rated

UL FR-263 is a two-component, spray-in-place, flexible, 100% solids polyether/polyester epoxide polyurea. It is fast-curing, textured, and designed for use as a Class A rated polyurethane surface. It can also be combined with abrasive particles to create a flexible membrane with anti-skid properties. UL FR-263 provides excellent adhesion to a variety of substrates.
