Accelerate Mold Pouring and Demolding Times

Save hours with Poly 74/75 Part X Accelerator. It can be added to Poly 74-Series, Poly 75-Series, Poly 77-Series & PT Flex Series polyurethane rubbers to speed up 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 Polytek Part X Accelerator needed varies from product to product and should be determined through experimentation.

Please Note: Part X should be added to Part A before mixing with Part B. Due to fast onset of gelling, it is possible for air bubbles to get trapped on or near the surface of the master mold. Read product label for additional information prior to usage.

  • Works with Poly 74-Series & 75-Series.
  • Works with Poly 77-Series & PT Flex Series polyurethane rubbers.
  • Decreases brush-on time between coats.
  • Quick Pour Times.
  • Expedites demold times.
  • 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.

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.
