Ensure resilient, long-lasting joint strength in new or remedial applications with SilPruf SCS2000 sealant.

SilPruf SCS2000 sealant creates an air and water tight barrier to help protect window perimeters, punched openings, flashings, and other critical junctions.

Supplied as a paste, this 100% silicone, versatile sealant cures to a durable seal, with the movement capability required to enable the most complex designs. SilPruf SCS2000 maintains its flexibility and strength, even after decades of exposure to weather and UV radiation - with the elasticity required to handle high-force winds and severe impact.

SilPruf SCS2000 sealant securely bonds to many substrates and finishes, including glass, polycarbonate, vinyl, plastics, wood, paints, coated and anodized aluminum, concrete, brick, wood, terracotta, natural stone, ceramic, porcelain, and EIFS. Some finishes may require a primer.

It is backed by world-class technical support and our project-specific warranty program.
