Exolit® 855 (TP) by Clariant is a liquid partial phosphoric acid ester. Acts as a flame retardant. Compatible with acid curing resins. Designed for fast curing varnish, highly transparent intumescent coatings on solid and engineered woods like chipboards, medium density fiber boards (MDF), oriented strand boards (OSB), plywood and veneered wood. Shows low smoke production in case of fire and easy application (brush or airless spray). Exolit® 855 (TP) has an optimized pot-life.
