BURN BARRIER™ 166 is a clear satin finish fire retardant varnish having a Class “A” Underwriters' Laboratory flame spread rating. When exposed to flame or high heat, the coating puffs up to form a thick insulating cellular foam. This foam layer retards the penetration
of heat, thereby reducing the flame spread (surface burning characteristics) and smoke development of combustible materials.
BURN BARRIER™ 166 is designed for use on interior wood surfaces where it is desirous to maintain the natural wood appearance, while obtaining a Class “A” flame spread rating.
BURN BARRIER™ 166 is suitable for use on wall paneling, ceiling panels and other such surfaces. We do not recommend this product for use on floors, doors, shelving, or in areas where there will be exposure to excessive moisture or splashing of water, as the coating is somewhat softer than conventional varnishes. (On hard use surfaces we recommend BURN BARRIER™ 129 and BURN BARRIER™ 130 Class “B” Fire Retardant Varnish System.)
BURN BARRIER™ 166 dries to a clear velvety satin finish. All surfaces that will be subjected to handling, washing or where a low, semi or hi-gloss finish is desired, should be overcoated with BURN BARRIER™ 167 UL rated Fire Retardant Varnish Overcoat. The use of BURN BARRIER™ 167 Overcoat greatly improved the moisture resistance, durability and cleansibility of BURN BARRIER™ 166.
