FLEXJOINT™ 700 Topcoat

Fluorocarbon-based Synthetic Rubber

FLEXJOINT 700 Topcoat is a two-component, fluorocarbon topcoat for application overtop polyurethane and polysulfide-based expansion joint sealants. It is a practical and efficient means to extend the chemical resistance of sealants for a wide range of aggressive chemicals including highly acidic compounds. By preparing the surface of polysulfide sealant with FLEXJOINT 700 Tackifier, adhesion of the topcoat to the sealant’s surface is optimized for superior durability.
