Marking material

Abstract

Abstract PURPOSE:To provide a marking material suitable for use in road marking and having excellent mechanical strength, spreadability, flexibility, etc., by mixing an org. polyisocyanate, an unsaturated polyester resin and a filler in a specified weight ratio. CONSTITUTION:An org. polyisocyanate (A) having at least two terminal isocyanate groups, such as tolylene diisocyanate or hexamethylene dissocyanate, an unsaturated polyester resin (B) and a filler (C) such as titanium dioxide or calcium carbonate are mixed together in such a proportion as to give 5-60wt% component a and 5-70wt% component C based on the amount of component B to obtain the desired marking material. In using this marking material, a catalyst such as methyl ethyl ketone peroxide and an accelerator such as cobalt octenoate are added thereto. The mixture is cast into the desired mold, and cured at ordinary temp. or by heating it.
