High Elongation MS Sealant And Hybrid Sealant

SEP-1911 is a one component silane end-capped polyether sealant, containing no solvent, no isocyanate, no small organic silicon molecule nor polymer.
It's environmental friendly, low VOC, and it would not contaminate substrate. It is cured by absorbing the moisture in the air at room temperature.
It performs excellent adhesive to variety of construction materials such as concrete, cement, stone, glass, aluminum alloy, PVC, PC etc., therefore it could be widely used in construction and infrastructure areas.
