Poly-Fast 72 Part D Thickener + Part A
Poly-Fast 72 Part D Thickener is a liquid additive that can be added to Poly-Fast 72-40 liquid rubber to make it thixotropic for brushing application.
Part D liquid thickener is used in combination with extra part A to turn Poly-Fast 72-40 from a pourable rubber to a brush-on rubber. Levels of thickening can be varied from that of a thin latex paint to a grease-like putty. One Part D added to 100 Parts B results in a light cream consistency. For every part of D used, one extra part of A is required. Part D is added to Poly-Fast 72-40 Part B first.
