NR/SC WHITE HIGH BUILD EPOXY PRIMER
The NR/SC White High Build Epoxy Primer is a two-component, high-build primer designed for professional auto body repair applications. This epoxy primer provides excellent adhesion and corrosion resistance on aluminum, steel, and existing primer surfaces, making it ideal for panel repairs and complete refinish work.
Mixed at a 1:1 ratio with 7603 catalyst, this primer offers an extended 8-hour pot life for efficient workflow management. The primer achieves a 15-minute flash time at ambient temperature and can be force-dried in 30 minutes at 140°F. With a VOC content of 458.69 g/L, this primer meets regulatory requirements while delivering professional-grade performance and coverage.
Proper spray booth ventilation and appropriate respiratory protection are required during application. The high-build formulation provides excellent surface smoothness and substrate coverage, reducing the need for additional primer coats in most applications.
