High Tensile Strength MS Sealant

SEP-9807 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 performs excellent bonding to variety of construction materials, such as concrete, cement, stone, glass, ABS,PC,PET,PBT etc.
