The F-25 A/B is a production oriented material system, that features a one to two hour demold time depending on part size and configuration. F-25 A/B has a 10-minute work time, which allows ample time to mix, vacuum de-gas and pour air-free parts.

Product Highlights:
  • Short demold time permitting good mold turn over
  • Ideal for intricate and flexible mold production
  • Exceptionally tough and resilient
  • Very easy to use
