In the formation of gaskets a liquid gasketing material comprising monomer, UV initiator and peroxy initiator is partially pre-cured by ultraviolet exposure in situ on a flange. The partially cured gasket is then mated with another surface and further cured anaerobically to produce an adequate gasket and sealant. The method is adaptable for high speed production-line techniques to be applied on a variety of flange shapes and sizes. The invention also relates to a composition suitable for gasketing, which combines UV and anaerobic curing capability, and the monomer component of which comprises a compound selected from certain, defined diacrylate-terminated esters. |
