Enhance Your Polyurethane Rubber Molding Experience

Take your polyurethane rubber molding to the next level with Poly 74/75 Additives from Polytek. These additives are designed to work with Poly 74-Series, Poly 75-Series, Poly 77-Series, and PT Flex Series polyurethane rubbers to provide a range of benefits. Whether you're looking to lower the viscosity of your mix, achieve a softer cured rubber, or accelerate your pour times and demold times, Polytek has you covered.

Part C Softener: Softer Cured Rubber and Lower Viscosity

Add Poly 74/75 Part C Softener to your polyurethane rubber to achieve a lower viscosity mix and a softer cured rubber. The amount of Part C needed varies from product to product, so it's essential to experiment to find the right ratio for your specific needs. For example, to soften Poly 74-30 Liquid Rubber (Shore A30) to a Shore A15, mix 1A:1B:1C by weight. Keep in mind that using Part C may result in longer cure times and some loss of strength in the cured rubber, as well as an increased tendency to shrink after repeated casting.

Part X Accelerator: Faster Pour Times and Demold Times

Poly 74/75 Part X Accelerator is the perfect solution for those who want to speed up their molding process. By adding Part X to your polyurethane rubber, you can reduce pour times and demold times, making it ideal for brush-on molds. The amount of Part X needed varies from product to product, but as a general rule, adding 3% Part X (by weight of the total mix) to Poly 74-30 or 74-29 Liquid Rubber can reduce the working time to approximately 8 minutes, while demolding is possible in as little as 4 hours after the final layer is applied.

The beauty of Poly 74/75 Additives lies in their versatility. Whether you're a seasoned pro or just starting out with polyurethane rubber molding, these additives give you the flexibility to customize your process to suit your specific needs.
