GE SCS1200® Silicone Sealant

Product # 120011

Seal building joints against rain, air, and noise

SCS1200 silicone construction sealant is used to seal building joints against rain, air and noise. This sealant effectively weatherproofs junctions of building materials and lends structure continuity. Also useful for sealing curtain wall, 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.

This sealant creates permanent, watertight bonds in combination with glass, ceramic, steel, granite, aluminum, and many plastics and painted surfaces.

Has resealed many structures successfully after the failure of other sealants. Used in maintenance applications, sealing around air conditioning, vents, or other wall penetrations, both indoors and outdoors. Ideal where long life, reliability, and a sound seal are required.

ADVANTAGES AND BENEFITS

Silicone Durability
- Cured silicone provides excellent long-term resistance to natural weathering, humidity, and high and low temperatures with negligible change in elasticity.

Fast Cure Time (24h)
- Fast cure technology minimizes tack-free and cure times. To be noted that the full cure can take up to 5 to 7 days,

Primerless Adhesion
- Bonds to many conventional substrates and finishes including glass, glass coatings, ceramic frits, fluoropolymer and powder coated paints, conversion coatings, and anodized aluminum

±25% Movement Capacity
- Can accommodate 25% movement in both extension and compression and has excellent recovery after cycling.

Cured Thermal Stability
- Once cured, the material remains fully elastic over a temperature range of -55°F (-48°C) to 400°F (204°C).

APPLICATION

Primerless Adhesion

- Bonds to many conventional substrates and finishes including glass, glass coatings, ceramic frits, fluoropolymer and powder coated paints, conversion coatings and anodized aluminum (Momentive recommends testing of all substrates for primerless adhesion).
- SCS1200 Construction silicone glazing sealant can be used in structural glazing applications.
- SCS1200 may be used as a weather seal product for general-purpose glazing, butt glazing and for tall glass-stiffened lobby systems.
- SCS1200 has been successfully tested in protective glazing applications and can be used in such applications.
- SCS1200 may be considered for sealing air conditioning, vents or other wall apertures such as glass block, metal/plastic signs and marine hardware.

IMPORTANT INFORMATION

Precautions

- 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. This may occur 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 done prior to use to confirm the suitability of the product with the materials with which it is intended for use

Consult the product's Tehnical Data Sheet for more information.

DISCLAIMER

Limitations
SCS1200 is not recommended and should not be used or applied in the following applications:
* In structural glazing applications unless Momentive Performance Materials has reviewed shop drawings for applicability and has performed adhesion and compatibility tests on project substrates, spacer materials and all accompanying accessories. Review and testing is done on a project-by-project basis. No blanket approval is given by Momentive Performance Materials for structural
glazing applications. Structural glazing industry guidelines (ASTM C 1401) suggest that drawings and details are to be
reviewed by all parties involved in the manufacture of an SSG system and for each building project.
* Mirrors.
* Wet, damp, frozen or contaminated surfaces.
* Masonry, stone, marble, lead, zinc coated metal, bare metal or surfaces subject to corrosion.
* 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).
* Horizontal decks, patio, driveway or terrace joints where abrasion or physical abuse is encountered.
* Where paintability is desired. Consider using SCS7000 Paintable weathersealant instead.
* Contact Momentive technical services for applications where sealant is used underwater or in continuous contact with water.
