GSA ALL PURPOSE SILICONE is a one-part, neutral cure, high quality silicone sealant designed for multi-purpose weatherproof and waterproofing applications. It has exceptional gunability even in extreme weather conditions and cures at room temperature by reaction with moisture in the air to produce a durable and flexible silicone rubber. It has excellent primerless adhesion to most construction materials.

FEATURES:

• Easy application with standard caulking guns.

• Neutral Cure – non-corrosive to sensitive substrates and suitable for uses on many non-porous, porous & alkaline substrates.

• Good adhesion – on curing will form a strong bond to most common building components without the use of primer; including typical substrates such as steel, glass, anodized aluminium, PVF2 coated surfaces and concrete.

• Good weatherability and virtually unaffected by sunlight (UV), wind, frost, rain, snow, ozone, or temperature extremes. It is a chemically stable, one part, ready to use material that has the consistency remains uniform over a wide range of temperatures -20°C to +50°C. This allows and facilitates the sealant installation to be applied easily at most working temperatures. Cured sealant will not harden in cold climate or soften at high heat condition, the service temperature range is from -40°C to +150°C. It will not become brittle, tear or crack, and stays flexible indefinitely

 TYPICAL APPLICATIONS:

GSA All Purpose Silicone is designed for sealing non-structural curtain wall joints, facade joints and system, EIFS, panels and metal cladding, expansion and movement joints, windows and perimeter joints. The product can be used for both new projects and remedial works. The sealant forms a durable, elastomeric, weather-tight and water-tight bond with most building materials in any combination, in particular; glass, ceramics and porcelains, stones (granite/ marble/ sandstone/ slate), masonry surfaces, tiles, wood, steel, anodized aluminium and painted surface. Primer is not required in most cases. It can be used for roofing construction materials such as galvanized and zinc-coated steel, aluminium and some plastics.
