SEP-985 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, without contaminating substrate. It is cured by absorbing the moisture in the air at room temperature.
Usually not need a primer before apply. It could adapt to thermal expansion and contraction duo to inherent elasticity.
It is specially used to fill gaps in the field of architecture.
