Abstract

1,187,592. Epoxy resin composition. CIBA Ltd. 18 July, 1967 [29 July, 1966], No. 34252/66. Addition to 1,008,268. Heading C3B. [Also in Division H2] An epoxy resin composition used in at least the parts exposed to the atmosphere of insulators for overhead wires consists of a cured 1,2-epoxy compound, containing per average molecule, n groups of Formula (1) directly attached to single or different O atoms; n is > 1; R and R<SP>1</SP> are each H or together denote -CH 2 CH 2 -; if two groups of Formula (I) are attached to the same oxygen atom at least one pair of R and R<SP>1</SP> must be -CH 2 CH 2 -. The 1,2-epoxy compound is cured with an aliphatic or heterocyclic polyamine or polythiol. The 1,2-epoxy compound and the curing agent are free from aromatic groups. If the oxygen atom or atoms attached to groups of Formula (I) are in ether linkage or linkages, a cycloaliphatic amine may be used as curing agent. Examples of suitable epoxy resins are diglycidyl ethers of cycloaliphatic dihydric alcohols and diglycidyl esters of cycloaliphatic dicarboxylic acids. The curing agent is preferably free from ethylenic or acetylenic unsaturation and of combined halogen. The cured composition preferably contains less than 2% by weight of halogen. When a polythiol curing agent is used an amine or polyamine accelerator may be present. Conventional fillers, plasticizers, pigments, dyestuffs, flame inhibitors and mould lubricants may also be present.
