Colder temperatures make boat painting and priming a real challenge. Add Quantum 45 Cold Cure Epoxy Primer Accelerator to Quantum 45 Epoxy Surfacing Primer or QuantumHB High Build Primer (both sold separately) to maintain cure times in cooler weather, and reduce cure times by as much as 50% in warmer weather.

Most epoxy primers cannot be applied below 55 F. Quantum45 Accelerator maintains cure down to 45 F and speeds cure times in warmer temperatures. Note: Do not use in topcoats.

To maximize gloss and adhesion, Quantum 45 Epoxy Primers are recommended for Quantum 99 Polyurethane Topcoat (sold separately), and are an essential component of the Quantum high solids repairable marine finish system.
