摘要:
Photocurable compositions and process for providing form-in-place gaskets using automated placement followed by photocuring of a pattern of a non-silicone composition comprising a liquid polyolefin oligomer, a reactive diluent, and a curative. The form-in-place gasket, after curing, has a level of total outgassing components of about 10 &mgr;g/g to about 45 &mgr;g/g. The curative responds to actinic radiation and heat, and may contain a photoinitiator. Optionally a photocurable, form-in-place gasket according to the present invention further comprises a thixotropic filler in an amount from about 8.0 wt. % to about 12.0 wt. %, and preferably comprises a fumed silica.
