Abstract
A blend of from 10 to 90 parts by Weight of a basic calcium sulphonate and from 90 to 10 parts by weight of a terpolymer of 50 to 99 wt. % of an olefin containing from 2 to 4 carbon atoms, 1 to 30 wt. % of an unsaturated ester which is a vinyl ester of a carboxylic acid or an ester of acrylic or methacrylic acid and 1 to 20 wt. % of an unsaturated carboxylic acid is particularly useful for car undercoatings for corrosion and chip resistance which may be applied as high solids coatings.
