Nitoseal PU40 sealant is a one component, moisture curing, non-sag, gun-grade polyurethane elastomeric sealant. It is designed to seal construction joints that are subject to movement. After cure, Nitoseal PU40 forms a flexible resilient rubber that has adhesion to a wide variety of substrates. A tack-free skin is formed during the curing process in 2 to 4 hours at normal conditions (23oC). Cure rates vary with changes in temperature and humidity.
