  • Type: Accelerator additive used in Quantum99 Polyurethane Topcoats and QuantumUV Clear Urethane Varnish.
  • Mixing: Do not exceed 1 oz. (30 ML)/mixed gallon or solvent pop and down gloss may result.


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.

Please refer to the Quantum99 Topcoat How To guide and the QuantumUV Clear Urethane Varnish How To guide for complete mixing and application details.
