Product Description:
BURN BARRIER™ 20-20 is a latex (water base) intumescent fire retardant paint, manufactured
and tested in accordance with Federal Specification TT-P-001932. This product is
designed for use on interior surfaces where it is either necessary or desirous to reduce
the surface burning characteristics of the substrate. It dries quickly to a flat matte finish,
having the appearance of a conventional flat paint. In the presence of heat or flame, the coating
puffs up (intumesces) and forms a thick sponge like cellular foam layer, this foam layer
insulates the substrate reducing the penetration of heat, thus retarding the flame spread and
prolonging structural collapse.
Fire Tests:
Flame Spread Ratings: Class “A”. When tested in accordance with ASTM E-84 (NFPA 255)
the coating obtained the following fire hazard classification. A complete Underwriters
Laboratory report is available below for download.
