NC-90
CASTABLE POLYURETHANE
NORMAC NC-90 (formerly NR-906) is a room-tempera- ture curing 90A two part castable polyurethane system. Designed using PTMEG Polyether with low-free technology which virtually eliminates isocyanate exposure. High tensile strength, increased flow rates, and easy processing, application areas include large open surfaces to small intricate molds. For use in dry, wet and immersion environments. Our application guide is available upon request.
