DOWSIL™ 757 Weatherproofing Sealant

Sealant for Photocatalytic Clean Glass is a neutral-cure, one-component, Si-hybrid based, low modulus, architectural grade sealant designed for weathersealing of most photocatalytic and hydrophilic clean glass surfaces where high movement is anticipated and high weather resistance is required to withstand increased temperature and UV radiation. It is ideal for expansion, connection, perimeter and other movement joints.
