TEROSON^® SI 34 is a transparent, gun-grade, solvent free, 1-part sealant based on neutral curing silicone rubber, which cures by reaction with moisture to a soft elastic product. After full curing, it is odourless, light resistant with good adhesion and chemical resistance. Due to its curing system, you can expect there to be no corrosion in edge areas or on laminated materials. Ideal for sealing aluminium, steel and rigid PVC parapet elements, expansion and butt joints, rigid PVC frame constructions and ventilation systems, acrylic glass constructions, machine and apparatus construction, and sealing steel to steel, as well as in the vehicle industry.
