Abstract
A composition that includes an epoxy compound, a thiol curing agent, a catalyst and a phosphorus--containing compound having at least one P--OH group and at least one organic moiety characterized by the presence of an ethylenically unsaturated group. The composition is particularly useful as a sealer for an adhesive joint.
Claims28
A composition comprising:
- (a) an epoxy compound based on glycidyl ether monomers of the formula ##STR5## wherein R' is alkyl or aryl and n is an integer of 1 to 6;
- (b) a thiol curing agent;
- (c) a catalyst;
- and
- (d) a phosphorus-containing compound having at least one P--OH group and at least one moiety characterized by the presence of an ethylenically unsaturated group.
A composition resulting from the mixture of:
- (a) an epoxy compound based on glycidyl ether monomers of the formula ##STR7## wherein R' is alkyl or aryl and n is an integer of 1 to 6;
- (b) a thiol curing agent;
- (c) a catalyst;
- and
- (d) a phosphorus-containing compound having at least one P--OH group and at least one moiety characterized by the presence of an ethylenically unsaturated group.
A two-part sealant system wherein a first part comprises an epoxy compound based on glycidyl ether monomers of the formula ##STR8## wherein R' is alkyl or aryl and n is an integer of 1 to 6 and a second part comprises a thiol curing agent, a catalyst and a phosphorus-containing compound having at least one P--OH group and at least one moiety characterized by the presence of an ethylenically unsaturated group.

- (b) a thiol curing agent;
- (c) a catalyst;
- and
- (d) a phosphorus-containing compound having at least one P--OH group and at least one moiety characterized by the presence of an ethylenically unsaturated group.
