Teroson SI 33 is a gun-grade, solvent free, one component sealant based on amine curing silicone rubber 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. After full curing Teroson SI 33 is odourless, light resistant and demonstrates good adhesion properties and a good chemical resistance. Due to its curing system, no corrosion in edge areas, as well as on laminated materials is to be expected. When sealing fresh, light coloured paints, a weak yellow colouration can occur during curing.
