General Electric 1200 construction silicone sealant is used to seal building joints to prevent rain, air and noise penetration. This silicone caulk effectively weatherproofs junctions of building materials and can also be used for sealing curtainwall, mullion and other building construction joints as well as for glazing steel and aluminum windows, painted and plastic coated wood windows, interior glass partitions, and skylights. Permanent watertight bonds are made with this caulk in combination with glass, ceramic, steel, plastics, and painted surfaces. In addition, many maintenance applications are possible where long life, reliability, and exterior sealing properties are required.
general purpose glazing, butt glazing and for tall glass-stiffened lobby systems
air conditioning vents
fluoropolymer and powder coated paints
SCS1200 sealant should not be used, applied or is not recommended:
For use on mirrors
For use on wet, damp, frozen or contaminated surfaces
For use on masonry, stone, marble, lead, zinc coated metal, bare metal or surfaces subject to corrosion
For use as the structural adhesive when bonding some IG unit types. Contact Momentive technical services for guidance
Under exceedingly hot or cold conditions (see Sealant Application section for more information).
For horizontal decks, patio, driveway or terrace joints where abrasion or physical abuse is encountered
Contact Momentive technical services for applications where sealant is used underwater or in continuous contact with water
This material requires atmospheric moisture to cure from paste to rubber and may not attain its listed final cured properties when used in designs or applications where silicone is encapsulated and without access to atmospheric moisture.
Some materials that bleed plasticizers or oils can cause a discoloration on the surface of sealants. When sealing to or over items such as rubberized gaskets, bituminous-based materials, butyl or oil-based products, oily woods, tapes, etc., Momentive Performance Materials recommends that compatibility testing be performed prior to use to confirm the suitability of the use of these materials when in contact with each other.
