| 摘要 |
A method of preparing a flexible, substantially tack free gasket by forming a liquid composition which is a radiation polymerizable admixture of a free radical polymerizable urethane (meth)acrylate monomer, free radical polymerizable urethane (meth)acrylate oligomer, or combinations thereof; a free radical polymerizable diluent; a free radical polymerization photoinitiator; a wax; a thixotropic agent; and optionally an adhesion promoter and a colorant. The composition is distributed onto a substrate and then exposed to actinic radiation to cure the liquid composition into a flexible, substantially tack free gasket having a Shore A hardness of from about A20 to about A80. |
