SMP Polymers & SPUR Polymers

Manta manufactures silane-modified polymers, including silane-terminated polyethers (MS/STP) and silylated polyurethanes (SPUR), for elastic sealants, construction adhesives, flooring adhesives and liquid membranes. The range covers low-, medium- and high-viscosity grades, different modulus levels and methoxy or ethoxy end-group chemistries. How to Choose an MS Polymer Three parameters guide most selections: viscosity, modulus and end-group chemistry. Low-viscosity grades suit self-leveling membranes, flooring adhesives and sprayable systems. Medium-viscosity grades are common base polymers for cartridge sealants and panel adhesives. High-viscosity grades build non-sag body in high-strength adhesive formulations. Alpha-silane grades are available for fast-curing and tin-free formulation work. Use each product page and TDS to compare viscosity, cure behavior and application fit. For competitor-grade benchmarking, send the reference grade or TDS to the Manta technical team.
