PRODUCT DESCRIPTION
NR-201 is a one part self-leveling,
moisture-curing, isocyanate
free sealant based on a unique
hybrid STPU (Silyl Terminated
Polyurethane) differentiating it
from the standard urethane-based
sealant. The silicone/urethane
hybrid chemistry utilized by the NR201 formula allows for a low odor,
non-yellowing, one-part, moisturecuring, 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.
It also has excellent UV resistance
in that it does not yellow, crack or
craze on long term expo- sure to
UV light. It has excellent abrasion
resistance withstanding the rigors of
pedestrian and vehicular traffic.
