GE® SilPruf® Silicone Sealant is a one-part, neutral cure sealant for use in most common weatherproofing applications on a wide variety of materials.
Basic Uses
After application, the sealant reacts with atmospheric moisture to produce a low-modulus, long-lasting, formed-in-place silicone rubber building joint and glazing sealant. It seals assemblies of metals, masonry, concrete, coated surfaces, plastics, wood, and other common building materials. SilPruf® is specially designed for use in butt joints or lap shear joints in weatherproofing and glazing applications subject to movement.
