Abstract: A curable composition comprising a mixture of homopolymers of an aliphatic polyisocyanate and a cycloaliphatic polyisocyanate, a polyester polyol or polyether polyol and a filler. The composition is particularly suitable for use in the manufacture of outdoor insulation system articles.

Abstract: A multiple component thermosetting epoxy resin composition comprising (A) at least one cycloaliphatic glycidyl-type epoxy resin without an ester group, (B) at least one curing agent selected from the group aliphatic amine, cycloaliphatic amine, and dicyandiamide, and (C) at least one silanized filler, which, in particular, is suitable for the manufacture of outdoor insulation system articles for electrical engineering by casting, potting, encapsulation, and impregnation processes, wherein said articles exhibit good mechanical, electrical and dielectrical properties, and can be used as insulators, bushings, switchgears and instrument transformers.

Abstract: A thermosetting epoxy resin composition comprising (A) a glycidyl-type epoxy resin comprising a mixture of (a1) from 10 wt % to 90 wt % of at least one cycloaliphatic glycidyl-type epoxy resin without an ester group, and (a2) from 90 wt % to 10 wt % of at least one cycloaliphatic glycidyl-type epoxy resin containing an ester group, each based on the total weight of (a1) and (a2), (B) at least one cationic curing agent, and optionally (C) at least one silanized filler, which, in particular, is suitable for the manufacture of outdoor insulation system articles for electrical engineering by casting, potting, encapsulation, and impregnation processes, wherein said articles exhibit good mechanical, electrical and dielectrical properties, and can be used as insulators, bushings, switchgears and instrument transformers.
