Quick Resources

ISOLATEK SBK-113 is a ready-mixed latex emulsion designed for use as a sealer/keycoat for direct-applied passive fire protection (PFP) systems. Formulated to improve bond along with pH barrier control, ISOLATEK SBK-113 is used when structural steel surfaces contain pre-existing protective primers and coatings. This multi-purpose product will seal against potential adverse affects that could result from application to these surfaces.
ISOLATEK SBK-113 contributes to the long-lasting in-place performance of the complete PFP system and provides the enhanced bond for Isolatek International’s wet spray, cement based fire-resistive materials.

ISOLATEK SBK-113 dries quickly and is easily identifiable due to its light yellow color. ISOLATEK SBK-113 is low VOC and contains no mercury, lead, or chromate ingredients. It is packaged in 100% recyclable plastic containers.
