About This Product


Ensure resilient, long-lasting joint strength in new or remedial applications with GE SCS2000 SilPruf sealant. GE SCS2000 SilPruf sealant creates an air and water tight barrier to help protect window perimeters, punched openings, flashings, and other critical junctions to adhere to most construction surfaces or substrates. Supplied as a paste (silicone rubber joint sealant), this 100% silicone, versatile sealant cures to a durable seal, with the movement capabilities required to enable the most complex designs. GE SCS2000 SilPruf 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.

You can be confident in the long lasting performance and capabilities of GE SCS2000 Silpruf in multiple weatherproofing applications to reliably withstand most weather conditions. Maintenance is easy with a simple cleaning solution of soap and water along with a light wipe down of the silicone sealants.

GE Silicone SCS2000 sealant has great versatility of uses within the GE product systems such as GE Enduris Roof Coatings, GE Elemax Air and Water-Resistive barrier Coating, most structural glazing applications, and architectural wall coatings. Some typical applications include: water resistive barriers for open joint cladding designs, detail sealant for roof coatings, edge or butt joints, interior or exterior seals, structural waterproofing glass systems, adhering pre-cured silicone weatherstripping, and general weather sealing construction applications.
