Epoxy smoothing compound

Claim 2

A coating composition for smoothing rough surfaces of steel, masonry, and concrete having desirable application and curing characteristics, said coating composition being prepared by mixing: (a) 44-45% by weight of a first component, said first component being a dispersion consisting of a polyamide adduct resin of 48-54% by weight, a polyamide resin of 3-4% by weight, a thixotrope additive of 12-24% by weight, a titanium dioxide pigment of 5-6% by weight, and a magnesium silicate pigment of 34-38% by weight; and (b) 44-45% by weight of a second component, said second component being a dispersion consisting of an epoxy resin of 55-66% by weight, a thixotrope additive of 10-20% by weight, a colorant pigment of 2-4% by weight, and a magnesium silicate pigment of 31-35% by weight.

Claim 3

A coating composition as recited in claim 1 wherein said first component is prepared by: (a) dispersing said polyamide adduct resin, said polyamide resin, and said thixotrope additive with a high speed disperser until the resulting mixture is heated to 140°-150° F. by the mixing process; (b) dispersing said pigments and said resulting mixture with a high speed disperser until the resulting dispersion has a minimum fineness of grind of 5 on the Hegmas Scale, said resulting dispersion being cooled as necessary to keep the temperature under 145° F. during said dispersing; and (c) cooling said resulting dispersion to 60°-70° F. for 24 hours before use in preparing said coating compound; and wherein said second component is prepared by: (a) dispersing said epoxy resin and said thixotrope additive with a high speed disperser until the resulting mixture is heated to 140°-150° F. by the mixing process; (b) dispersing said pigments and said resulting mixture with a high speed disperser until the resulting dispersion has a minimum fineness of grind of 5 on the Hegmas Scale, said resulting dispersion being cooled as necessary to keep the temperature under 145° F. during said dispersing; and (c) cooling said resulting dispersion to 60°-70° F. for 24 hours before use in preparing said coating compound.
