Cost-1138 is neutral silicone weather-proofing sealant. The main components are organic silica-based support adhesive, silicone oil, calcium carbonate powder and other chemical accessory ingredient, and synthesize to a one part humidity solidifying sealing material through chemical reaction. This product has excellent resistance to weathering and outstanding sealing performance. With aluminium film soft package
uOne part, medium modulus. It will appear excellent extrusion and thixotropy if construct at 4°C-40°C. Easy to use.
uWith excellent resistance to weathering, aging, ultraviolet ray and ozone.
uGood adhesive; after solidifying it will have good adhesive with most construction materials without base coat.
uExcellent resistance to high and low temperature. After solidifying, it will not become fragile, vulcanizing and cracking at -50°C, and at +150°C it has good flexibility without soft, degradation.
uHigh capacity of bearing displacement, for the walls normal stretching and shearing deformation, it can maintain the same performance, Play an effective role of sealing.
uNeutral solidifying. No corrosion to metal, plating film glass, concrete, marble, granite and other construct materials. It is applying abroad.
