Abstract
Smoke suppressed flame retardant thermoset resin compositions comprise smoke suppressant bicyclic phosphate compound(s), flame retardant(s) and unsaturated polyester or other thermoset materials. These compositions exhibit a reduced tendency to smoke under conditions of burning.
Claims12
A smoke suppressed thermoset resin composition comprising:
- a thermoset polyester resin;
- and
- a mixture comprising:
- at least one flame retardant agent selected from alumina trihydrate or magnesium hydroxide;
- and
- a smoke suppressant comprising at least one bicyclic phosphate compound of the formula:
- ##STR2## where X is OH, OR' or OC(O)R';
- R is H or a saturated or unsaturated straight-chain or branched-chain C.sub.1 -C.sub.17 alkyl;
- and R' is a saturated or unsaturated C.sub.1 -C.sub.17 alkyl.

A method for suppressing the tendency of thermoset polyester resin compositions to smoke under conditions of burning comprising the step of incorporating therein an effective amount of a mixture comprising:
- a flame retardant agent selected from alumina trihydrate or magnesium hydroxide;
- and
- a smoke suppressant comprising at least one bicyclic phosphate compound of the formula:
- ##STR3## where X is OH, OR' or OC(O)R';
