Primer paint has been developed based on lignin obtained from black liquor as a partial replacement (40%) for conventional alkyd resin.
Primer paint has been developed based on lignin obtained from black liquor as a partial replacement (40%) for conventional alkyd resin. Efforts were made to prepare a novel alkyd resin with short oil length (20%) using chain stopper. Overall consumption of petroleum solvent (25%) in primer is lesser than conventional primer (40% solvent). The cost of present product is less than the conventional product.
