Patent Images
1. A low density, fire-resistant epoxide composition comprising:
- (a) from 10 to 75 percent by weight of an organic epoxide compound having an epoxide functionality of at least 1;
(b) from 1 to 25 percent by weight of an epoxide hardener;
(c) from 20 to 50 percent by weight of a smoke suppressant;
(d) from 10 to 25 percent by weight of a filler capable of reducing the density of said composition; and
(e) from 1 to 10 percent by weight of an organic phosphorous-containing compound selected from the group consisting of alkyl phosphates, aryl phosphates, alkylphosphonates, arylphosphonates, and mixtures thereof,wherein said composition contains from about 3 to 10 weight percent bromine.

28. A low density, one part, self-extinguishing epoxide composition comprising
(a) from 15 to 25 percent by weight of an organic epoxide compound having an epoxide functionality of from 2 to 4; -
(b) a liquid epoxide hardener present in a quantity sufficient to provide a weight ratio of said epoxide to said hardener in the range of from about 0.7/1 to 1.5/1; (c) from about 25 to 35 percent by weight of an inorganic hydroxide smoke suppressant; (d) from 10 to 25 percent by weight of an inorganic, filler capable of reducing the density of said composition; (e) up to about 10 percent by weight of an inorganic boron-containing compound; (f) from 1 to 10 percent by weight of an inorganic phosphorous-containing compound; (g) up to about 5 percent by weight of a wetting agent;
wherein said composition comprises from about 3 to 10 weight percent bromine and has a weight ratio of organic compounds to inorganic compounds of 1.2 to 1 or less.
