Cross-linking of thermosetting resins by means of heating with saturated perfluoropolyether vapour.

摘要

The cross-linking or curing of thermosetting resins and of hot curable elastomers is carried out by heating the material or the article comprising the resin (or the elastomer) by means of saturated vapour of a commercial perfluoropolyether having an average boiling point corresponding to the temperature necessary for the cross-linking and having a boiling point range not exceeding 12 DEG C (measured according to ASTM D 1078) in the presence of a chlorofluorohydrocarbon secondary vapour.
