Info & Guides

The Quantum⁹⁹ Urethane Accelerator will maintain the 75°F cure profile when added at 5 ML/mixed gallon every 5°F below 75°F. At 75°F, 1 oz (30 ML)/mixed gallon will reduce the Dry to Tape time to 4 hours; the Dry to Touch time to 1 hour.

This product can be used at temperatures up to 100°F, though caution should be taken as pot life will be reduced.
