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.
- By adding 3% Part X (by weight of the total mix) to Poly 74-45, the working time is reduced from 30 minutes 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 from 45 minutes 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.
