GE SilPruf® SCS2000 Silicone Sealant is a one-part silicone sealant for use in most common weatherproofing applications on a wide variety of materials. After application, the sealant reacts with atmospheric moisture to produce a low-modulus, long life, formed-in-place silicone rubber building joint and glazing sealant.
Limitations:
Structural glazing applications require that GE Silicones give written approval of the use of GE SilPruf® SCS2000 Silicone Sealant for each building project. Drawing review and substrate testing must be completed prior to sealant use on a project. Review and testing is done on a job -to-job basis. No blanket approval is given by GE Silicones for structural glazing applications. Use only approved back-up materials, spacers and setting blocks to ensure sealant compatibility and function. GE SilPruf® SCS2000 Silicone Sealant is not recommended for use where abrasion or physical abuse is encountered in horizontal joints on- or below-grade.
The sealant is not recommended for use in locations subject to continuous water immersion. GE SilPruf® SCS2000 Silicone Sealant should NOT be applied to:
•Concrete surfaces which contain residual form oil or other bond breaking contaminants that may interfere with sealant adhesion
•Building materials which might bleed oil or solvents these include, but are not limited to, impregnated wood and certain vulcanized rubber gaskets or foams, tapes or failed sealants and caulking compounds. WHEN SILPRUF SILICONE SEALANT IS USED IN REMEDIAL WORK, ALL OLD SEALANT MUST BE REMOVED
•Areas where atmospheric contaminants might change the appearance of light colored sealants silicone sealant is weather resistant and resists chalking, degradation and erosion. As a result, environmental contaminants tend to cling to the sealant and the sealant surface may take on the color of the contaminant. Darker colors should be used to minimize this effect
•Reflecting, high-gloss or light-colored surfaces where aesthetics are critical, until adequate on-site sealant, surface and ambient atmospheric tests simulating building design are conducted to ascertain material compatibility and migration to adjacent surfaces under actual use conditions
•Unpredictably absorptive surfaces such as marble or limestone, unless a standard of appearance has been agreed upon by the seller and the purchaser as a result of testing for stain or discoloration
•Totally confined spaces, as the sealant requires atmospheric moisture for completion of cure and generation of properties
•Surfaces which will be painted, as painting over rubber is not recommended. The paint film does not stretch with the extension or compression of the rubber and the adhesion of the paint to SilPruf sealant is not adequate
•Unprepared or wet surfaces
•Do not use water for tooling and do not apply to wet or damp surfaces
•Surfaces where adhesion has not been verified by on site testing under actual use conditions

General Applications:
GE SilPruf® SCS2000 Silicone Sealant is designed for use in structural glazing applications such as in -shop and field glazing of curtain wall modules where glass lights are attached to the metal framing system with the structural sealant. SilPruf® Silicone Sealant may also be used to seal assemblies of metals, masonry, concrete, coated surfaces, plastics, wood and other common construction materials. GE SilPruf® SCS2000 Silicone Sealant is specially designed for use in butt joints or lap shear joints in weatherproofing and glazing applications subject to movement. The low-modulus characteristic reduces strain on the substrate surface and the electrometric quality allows excellent recovery from extension and compression cycling. GE SilPruf® SCS2000 Silicone Sealant may be factory or field applied to glass, metal and plastics in glazing and curtain wall assemblies to produce a primary or secondary seal against water, air and dust penetration.
