NC-60D
CASTABLE POLYURETHANE
NORMAC NC-60D (formerly NR-987) is a room-tempera- ture curing 60D two part castable polyurethane system. Designed using PTMEG Polyether with low-free technology which virtually eliminates isocyanate exposure. This product offers a very low coefficient of friction allowing for non-sticking and improved material flow rates. Easily processed, for use in dry, wet, and immersive environments. Application areas include large open surfaces to small intricate molds. Our application guide is available upon request.
