PM Sealant is a Silyl Terminated Polyether (STPE) non-isocyanate detailing sealant that combines the strength of polyurethanes with the weathering-resistance of silicones. PM Sealant can withstand the most stringent requirements for high-performance bonding and elasticity under severe aging and UV-weathering conditions without cracking or yellowing when subjected to extended UV-light exposure. PM Sealant is used for penetration detailing as a seam edge and patching detailing sealant along the transition construction joint between two pours, and for sealing an applied-termination bar. Compliances: Conforms to ASTM C920, Type S, Grade NS, Class 50, Use T, NT, I, G and A. AAMA 802.3 Type II Back Bedding Compound. PM Sealant is a single-component 100% solid moisture-cured elastomeric (STPE) sealant. PM Sealant benefits include:
Replaces silicone and urethane sealants.
Does not require a primer.
Cures rapidly, even at low temperatures, and retains its properties to -50°F (-45°C).
Non-reactive, therefore will not oxidize or corrode metals.
Does not contain VOCs.
Provides a continuous smooth surface.
