Poly 74/75 Part X Accelerator

Add Poly 74/75 Part X Accelerator to Poly 74-Series, Poly 75-Series, Poly 77-Series & PT Flex Series polyurethane rubbers to accelerate pour times and demold times. Part X is most useful when making brush-on molds to decrease the time needed between coats. The amount of Part X needed varies from product to product and should be determined through experimentation.

Examples: By adding 3% Part X (by weight of the total mix) to Poly 74-30 or 74-29 Liquid Rubber, the working time is reduced to approximately 8 minutes -- in the time it takes to mix the next batch, the previous layer gels enough to apply the next coat. Demolding is possible in as little as 4 hours after the final layer is applied. By adding 1% Part X (by weight of the total mix) to Poly 75-80 Liquid Rubber, the working time is reduced to approximately 10 minutes and demolding is possible in as little as 6 hours.

NOTES: Exercise caution when using Part X for poured molds since the rapid onset of gelling may trap air bubbles on or near the surface of the master. Add Part X to Part B prior to mixing with Part A. For additional information, read the Technical Bulletin associated with your product.
