HB BODY H752 HARDENER FOR TOPCOATS SLOW is a premium-grade isocyanate-based hardener specifically designed to be used with HB BODY’s high solids (HS) and scratch-resistant (SR) 2K clear coats. Its slow-curing profile makes it ideal for large surface areas, full vehicle resprays, and applications in high ambient temperatures—ensuring optimal flow, leveling, and finish quality.
