The USC® Urethane Reducer line is engineered for high-quality refinish work in professional spray environments. Formulated with virgin-grade solvents, these reducers ensure optimal flow, leveling, and atomization when spraying urethane-based primers, basecoats, or clearcoats.
Choose the reducer that best matches your shop conditions for consistent and flawless finishes:
Fast (4210-1) – Ideal for cooler temperatures and quick flash times.
Medium (4215-1) – Designed for moderate conditions (75°F–85°F / 23°C–29°C).
Slow (4225-1) – Best for hotter climates, maximizing open time and reducing solvent pop.
No matter your booth setup or project type, USC’s urethane reducers deliver professional-grade results with fewer reworks and smoother finishes.
