Abstract
A process for the preparation of pressure sensitive adhesive tapes where cationic cure is conducted against liners and substrates with low moisture content and in an environment where moisture ingress during cure is prevented.
Claims20
A process for coating and curing a cationic curable pressure sensitive adhesive on a release liner and/or backing substrate whereby a cationic curable adhesive is coated on a release liner and/or backing substrate having a low moisture content and then allowed to cure under low moisture conditions.
7-12. (canceled)
A process of preparing a cured adhesive article comprising coating a cationic curable adhesive onto a film substrate having a moisture content of less than about 5% and initiating cure, wherein the moisture content of the coated substrate is maintained at a level of less than about 5% until the adhesive is substantially filly cured.
