Abstract
Liquid, solventless, complex polymeric compositions are provided which thermoset at ambient temperatures through addition polymerization. In a preferred embodiment, a two component system includes a first component comprising amine or acrylate terminated polyurethanes, polyurethane-ureas or polyureas and a second component comprising di or polyacrylates. By adding an excess of acrylate, a one component system can be formed which thermosets when exposed to ultraviolet radiation.
Claims6
A copolymer comprising the addition reaction product of:
- a first component comprising at least one amine or acrylate terminated polyurethane, polyurethaneurea or polyurea;
- and
- a second component comprising at least one di or polyacrylate with a structure other than that of said first component.
