Two Part Urethane Foam
The two part urethane liquid, expanding rigid urethane foam is a closed cell, pourable foam that resists the absorption of water. Once fully cured, the foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting. Pour the solution in multiple layers with excellent bonding between layers. Keep in mind that temperature below 75°F will lower the expansion rate, therefore requiring more foam. The ideal working temperature is 75°F to 80°F or above.
- Expansion rates & time given = Temperature critical
- Working time before foaming: Approx. 45 seconds
- Time before full expansion: Approx. 5 minutes
