OSI® VP-275™ Multi Purpose 100% Silicone Sealant OSI VP-275 is a one-part, low modulus, neutral curing silicone sealant specifically formulated for use on vinyl products in the siding & window industry. The high performance characteristics of VP-275 provide excellent primerless adhesion to most porous and non-porous building materials. VP-275 cures at room temperature by reaction with moisture in the air to produce a permanently flexible seal that is weatherproof and waterproof. It offers superior resistance to oxidation, UV light, temperature variations and is non-corrosive to most metals. The low modulus properties of the sealant allow it to withstand extension and compression movement capability up to ±25% of the original joint width.
