Polyester Putty

Talc is a very important functional filler in putty made of unsaturated polyester, e.g. for car and truck bodies. It is used here in proportions of upto 60% by weight. Thus, the quality of the putty ingredient “talc” has a significant effect on putty performance. The softness of pure talc leads to good sandability of polyester putties. It gives high-quality surface finish after sanding operations.The pot life is adversely affected by the content of soluble contaminants. Golcha Associated Talc exhibits the least content of soluble HCl and offers the longest pot life.
