Silane modified polymer
TEROSON® MS 9120 is a gun-grade silane-modified polymer sealant formulated free of solvents, PVC, isocyanates, or silicones. It is available as a black, white, or grey thixotropic paste. As an advanced bonding and sealing agent for seams, joints, and plastic parts in vehicle body repairs, TEROSON® MS 9120 exhibits excellent gap-filling properties and spot-weldable capabilities. It adheres to various substrate properties without the need for a primer, providing skin formation in roughly 10 minutes upon reaction with moisture to form a soft elastic product with no shrinkage or sag. TEROSON® MS 9120 also offers excellent UV and weather resistance suitable for both interior and exterior applications.
