Abstract
An epoxy-resin based composition thermoset from a coating applied centrifugally to the internal cylindrical surface of an axial-flow compressor housing (see Division F1), consists of, by weight, 160 to 194, preferably 177 parts, of a first epichlorohydrin-bisphenol-A epoxy resin having a viscosity at 65.6 DEG C. within the range 300 to 500 cps. and an epoxide equivalent weight within the range 235 to 255; 22 to 26 parts, preferably 24 parts, of a second epichlorohydrin-bisphenol-A epoxy resin having a viscosity at 25 DEG C within the range 11,000 to 14,000 cps. and an epoxide equivalent weight within the range 187 to 193; 60 to 72 parts, preferably 66 parts, of hexahydrophthalic anhydride; 225 to 275 parts, preferably 250 parts, of finely divided alumina; and 1.25 to 1.55 parts, preferably 1.40 parts of diethylaminoethanol which is a catalyst. The compressor housing may be of stainless steel, aluminium, magnesium or alloys thereof. All the constituents of the composition apart from the catalyst are preheated to 200 DEG F and thoroughly blended. The catalyst is blended into the preheated mixture shortly before coating. During coating, the mixture is preferably maintained at substantially 200 DEG F and the compressor housing is rotated rapidly as by a lathe. After coating, the housing is rotated at 2900 to 3200 r.p.m. and maintained at 200 to 250 DEG F for four hours. The housing is then removed from the lathe and maintained at substantially 250 DEG F for fourteen hours.
