Fire Retardant Varnishes


Flame Control No. 166 is a clear satin finish fire retardant varnish having a Class "A" Underwriters' laboratories 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.

RECOMMENDED USES: No. 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. No. 166 is  suitable for use on wall paneling, ceiling panels and other such surfaces. Not recommended for use on floors, doors, shelving, or in areas where there could be exposure to dampness, high humidity, moisture  or water, as the coating is somewhat softer than conventional varnishes, and may turn milky if exposed to damp or humid conditions. (On hard use surfaces or in areas where damp and humid conditions  could be encountered, we recommend Flame Control No. 129 and No. 130 Class "B" Fire Retardant Varnish system). No. 166 dries to a clear velvety satin finish. All surfaces that will be subjected to handling,  or where a low, semi or hi-gloss finish is desired, should be topcoated with Flame Control No. 167 Fire Retardant Varnish Overcoat. The use of No. 167 Overcoat greatly improves the durability of No. 166.  

Flame Control No. 167 is a Class "A" fire retardant varnish overcoat. Used as a topcoat for No. 166 intumescent fire retardant varnish. No. 167 is available in three sheens, low, semi or hi-gloss. No. 166 fire  retardant varnish must be applied prior to the application of No. 167, to achieve a Class "A" fire rating.

RECOMMENDED USES: The use of No. 167 as a topcoat over No. 166, greatly improves the durability,  and cleansibility of No. 166. We recommend that No. 167 be used to topcoat No. 166 on all surfaces that will be subjected to handling or where a low, semi or high gloss finish is desired.
