Hōseki Premium Urethane Accelerator is a premium system additive engineered to significantly reduce curing, dust, tack, and tape times for Hōseki Acrylic Urethane Primers and Clearcoats. Formulated to accelerate production without sacrificing pot life, this accelerator saves valuable time and boosts overall shop efficiency.

For optimal results, add 1/2 oz. up to 1 oz. per Ready-To-Spray (RTS) quart of Primers & Primer Surfacers. For Clearcoats, add strictly 1/2 oz. per RTS quart. Critical Caution: Do not use in products other than those listed. Excessive amounts of accelerator may cause yellowing, staining, or severe embrittlement of the final finish.
