Abstract
Plastisols useful for automobile undercoatings, anti-noise compositions, adhesives, sealing compositions and coatings for untreated, pretreated, phosphated, primed and prelacquered metal bases are improved by the addition of coke dust and coal dust fillers. The carbon dust fillers have a particle size of about 0.5 to 1000 microns and they are used in a concentration of about 9 to 90% by weight based on the total weight of plastisol and carbon dust. The carbon dust filled plastisols have a specific gravity of about 1.1 to 1.3.
