TEROSON MS 647 is a gun-grade, one component adhesive / sealant based on silane modified polymer, which cures by reaction with moisture to a soft elastic product. The skin formation and curing times are dependent on humidity and temperature, and the curing time also depends on joint depth. By increasing the temperature and moisture these times can be reduced; low temperature as well as low moisture retard the process. TEROSON MS 647 is free of solvents, isocyanates, silicones and PVC, and is odorless. It demonstrates good adhesion to many substrates.The sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications. TEROSON MS 647 demonstrates the strength necessary for elastic bonding.
