Abstract
A stable and non-separating catalyst paste, reactive into a polyester system, said paste comprising a diacyl peroxide; a plasticizing amount of a vinyl-reactive di(hydroxyloweralkoxyalkyl) fumarate plasticizer; a finely divided mineral filler, e.g., calcium carbonate, in an amount sufficient to prevent the composition from physically separating into its components; the remainder, if any, being water.
Claims8
A storage stable, reactive peroxide paste composition comprising:
- (a) dibenzoyl peroxide or a dibenzoyl peroxide having one or more substituents selected from halogen, lower alkyl or lower alkoxy;
- (b) a fumarate plasticizer therefor comprising a di-(hydroxylower-alkoxylower alkyl) fumarate;
- and
- (c) finely divided particulate mineral filler in an amount sufficient to prevent the composition from physically separating into its components.
