Abstract
The curing of shellac with epoxy resin by fusion was studied in detail by Tripathi et al. An improvement in the film properties was noticed for the varnishes prepared from the cured products of 70 parts of shellac with 30 parts of epoxy resin. Similar study was made on the modification of shellac with phenolic resin by Kumar and Sankaranarayanan and Kumar. The films obtained from the modified varnishes showed improved heat and water resistance.
