Poly 74/75X is used in small amounts to accelerate the cure of 74/75/77 & PT Flex series of polyurethane rubbers. The addition also reduces working time.
Add Poly 74/75X to any 74 Series, 75 Series or PT Flex rubber to speed the cure. Stir Poly 74/75X into the Part B prior to adding the Part A. 1 - 3% of total mix will decrease demould time to as fast as 4 - 6 hours. Demould times will vary depending on product and temperature. We always advise testing to achieve optimum results.
