Use of unconventional oils in surface coatings: blends of alkyd resins with epoxy esters

Abstract

The alkyd resin of short oil length with low acid value was modified with novolac‐based epoxy esters, prepared by using tobacco seed oil fatty acids. The prepared blends were cured using an aliphatic amine as curing agent. The films of cured resins were applied over various panels and their film characteristics were studied. It was found that the scratch hardness and corrosion resistance increased with the increase of epoxy esters in the blend. The chemical resistance was also studied and found to be better with increasing epoxy esters in the blends.
