NR-201 is a one part self-leveling, moisture-curing, isocyanate free sealant based on a unique hybrid STPU (Silyl-Terminated Poly Urethane) differentiating it from the standard urethane-based sealant. The silicone/urethane hybrid chemistry utilized by the NR-201 formula allows for a low odor, non-yellowing, one-part, moisture-curing, STPU sealant.
It has been developed specifically for sealing dynamic joints between materials of dissimilar porosity, coefficients of expansion and surface textures, as well as embedding detector loop wire for traffic signals and parking gates. It cures to a medium modulus rubber
with extraordinary adhesion, capable of accommodating joint movement of +25% of the original joint width.
