Teroson MS 9399 Modified Silane Polymer Black, 400ml

TEROSON® MS 939 is a one-component elastic adhesive and sealant based on silane-modified polymer (MS Polymer) technology, developed for bonding and sealing applications requiring high mechanical strength combined with excellent flexibility. It cures with atmospheric moisture to form a durable elastomeric material with outstanding UV and weather resistance. :contentReference[oaicite:3]{index=3}

Its high-viscosity thixotropic formulation provides excellent sag resistance, even on vertical surfaces, while delivering strong initial grab and reliable long-term performance. Free from solvents, isocyanates, silicones and PVC, it is suitable for a wide range of substrates and both interior and exterior applications. :contentReference[oaicite:4]{index=4}
