NC-80
CASTABLE POLYURETHANE
NORMAC NC-80 (formerly NR-806P) is a room-tempera- ture curing 80A two part castable polyurethane system. Designed using PTMEG Polyether with low-free technology which virtually eliminates isocyanate exposure. Designed to reduce small particle abrasion in dry, wet, and immersion environments. Easily processed, application areas include large open surfaces to small intricate molds. NC-80 has proven durability and performs in a wide variety of wear applications. Our application guide is available upon request.
