Abstract:
A polymer-based blend comprising:90 to 100 parts by weight low viscosity epoxy resin;1 to 10 parts by weight of an aliphatic glycidyl ether epoxy diluent, whereinsaid diluent has a viscosity which is lower than the viscosity of said low viscosity epoxy resin;40 to 50 parts by weight polyoxypropyleneamine curing agent;30 to 100 parts by weight intumescent powder;90 to 110 parts by weight hollow ceramic microspheres having a density of between 0.30 and 0.60 grams per cubic centimeter; and0.01 to 0.10 part by weight air release agent wherein said hollow ceramic microspheres are dispersed uniformly throughout said polymer-based blend.
