SEP-985 is a one component silane end-capped polyether sealant,containing no solvent, no isocyanate, no small organic silicon molecule norpolymer.
It's environmental friendly, low VOC, without contaminatingsubstrate. It is cured by absorbing the moisture in the air at roomtemperature.
Usually not need a primer before apply. It could adapt to thermalexpansion and contraction duo to inherent elasticity.
It is speciallyused to fill gaps in the field of architecture.
