Abstract: The composition includes a polyester resin comprising at least one ?,?-unsaturated ester group, an epoxy resin, a compound comprising at least one hydroxyl group; and a photoinitiator that generates acid on exposure to actinic radiation. A method of repairing a damaged surface using the composition is also described.

Abstract: The composition includes a polythiol having more than one thiol group and an allylic resin having more than one allyl group. The composition typically includes inorganic filler. Typically, at least one of the polythiol or the allylic resin has more than two thiol or allyl groups, respectively. A two-part body repair composition including the composition and use of the composition as a body repair composition are also disclosed. Methods of repairing a damaged surface are also disclosed. The method can include combining a composition with at least one of an organic peroxide or hydroperoxide, applying the composition including at least one of the organic peroxide or the organic hydroperoxide to the damaged surface, and curing the composition on the damaged surface to provide a cured composition. The composition includes a polythiol having more than one thiol group, an allylic compound having more than one allyl group, and inorganic filler.

Abstract: The composition includes a liquid polyester resin comprising at least one ?,?-unsaturated ester group, a tertiary amine accelerator, and up to five percent by weight of a reactive diluent having a flash point up to 150° C. A method of repairing a damaged surface using the composition is also described.
