One-component High Elongation Sealant Construction Sealants

SEP-9811 is a one component sealant based on silane end-capped polyether, without solvent, free isocyanate, small organic silicon molecule and polymer.
It is environmental friendly, low VOC, and would not dirt the substrate, which is curing by absorbing the moisture from air in the room temperature.
It's widely applied to infrastructure construction fileds, which has excellent adhesion to different base, such as concrete, cement, stone, glass, aluminum alloy and other building materials.
