Silicone Sealants for Glazing & Storefront

Neutral cure silicone for glazing, curtain wall and storefront work, sold by the case and stocked on Staten Island. Weatherproofing grades for perimeter and movement joints, a structural grade for hidden frame bonding, and DOWSIL 795 where a job specification calls for it by name.

Every sealant here is neutral cure, which matters on a facade: an acetoxy sealant gives off acetic acid as it cures and can attack anodised aluminium and galvanised metal. Four colours ship from the shelf; around 200 more are made to your sample.

All of them come in the same 20 fl oz foil sausage, so one gun serves the whole range.
