Abstract
The invention relates to a curable two- or multi-part composition with (a) optionally an at least bifunctional epoxy-containing compound; (b) an at least bifunctional nitrogen-based curing agent suitable for epoxy curing; (c) a radiation-curable hybrid compound having both one or more radiation-curable methacrylate groups and one or more epoxy groups; (d) a radical photoinitiator; (e) optionally an accelerator for epoxy curing, and (f) optionally further additives. In addition, the invention relates to a method for the bonding, casting, molding or coating of substrates using the composition.
Claims17
A curable two- or multi-part composition, comprising:
- (a) optionally an at least bifunctional epoxy-containing compound;
- (b) an at least bifunctional nitrogen-based curing agent suitable for epoxy curing selected from the group of primary and secondary amines, wherein the curing agent is present in liquid form at room temperature;
- (c) a radiation-curable compound comprising at least one hybrid compound (c1), wherein the at least one hybrid compound (el) has both one or more radiation-curable methacrylate groups and one or more epoxy groups, wherein the at least one hybrid compound (c1) is bifunctional or of a higher functionality with regard to the epoxy groups and/or the radiation-curable methacrylate groups,
- wherein an amount of substance of the radiation-curable methacrylate groups of the at least one hybrid compound (c1) is at least 50%, based on the radiation-curable equivalent weight (SEW) of the composition;
- and
- wherein the at least one hybrid compound (c1) can be obtained by reaction of a methacrylate-containing isocyanate or a methacrylate-containing silane with a hydroxy-functional epoxy compound;
- (d) a radical photoinitiator;
- (e) optionally an accelerator for epoxy curing;
- and
- (f) optionally further additives.
