Fast Cure, Non-corrosive
Silicone Adhesive Sealant TSE399
Page 1/3
TSE399 is a one-component, fast cure, non-corrosive silicone adhesive sealant that cures on exposure to
atmospheric moisture to form an elastic silicone rubber. TSE399 is easily pourable and has excellent
corrosion-free adhesion to metals, including copper, plastics, ceramics, glass, etc without the use of
primers.
