Abstract

Indian patent No.60166 describes the preparation of a stoving varnish based on cashew Nut shell Liquid (CNSL).Essentially the process consists decarboxylating the commercial CNSL at 160°-170°C and then heat polymerising the material at 315°C.0·75%W/W litharge is then incorporated at 315°C. 1% manganese resinate at 260°C and lead linoleate dissolved in the minimum quantity of turpentine at 160°C. The varnish base obtained is then thinned with an equal weight of turpentine.
