Silicone sealant is based on polydimethylsiloxane as the main raw material, supplemented by crosslinking agent, filler, plasticizer, coupling agent, catalyst mixed in vacuum paste, at room temperature through the reaction with water in the air, curing to form elastic silicone rubber.
Single-component silicone glass glue is a salt-like material that solidifies into a tough rubber-like solid once it comes into contact with moisture in the air. Silicone glass adhesive has strong adhesion, large tensile strength, and has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and adaptation to hot and cold changes. Coupled with its wider applicability, it can realize the bonding between most building materials products, so the application value is very large. Silicone glass glue does not flow under its own weight, so it can be used over the top or side wall joints without sagging, collapsing or flowing away. It is mainly used for dry cleaning of metal, glass, most non-oily wood, silicone resin, sulfurized silicone rubber, ceramics, natural and synthetic fibers, and many paint plastic surface bonding. The use of good quality silicone glass glue below zero degrees Celsius will not occur extrusion, physical characteristics change and other phenomena.
use
(1) Acid glass glue. 1, suitable for sealing, blocking leakage and weatherproof purposes, indoor and outdoor both suitable (indoor effect is better), anti-seepage and anti-leakage effect is significant. 2, bonding various interior decoration of the car, including: metal, fabric and organic fabric and plastic. 3, joint heating and cooling equipment on the gasket. 4, on the metal surface to install no screw holes of the bar, nameplate and paint and plastic materials. 5. Seal the window on the oven door, the flue on the gas appliance, the pipe joint, and the passageway door. 6, for gear box, compressor, pump to provide instant formation of anti-leakage pad. 7. Seal the cabin and window. 8, trailer, truck cab window sealing. 9. Glue and seal equipment components. 10, the formation of anti-wear coating. 11. Inlay and fill thin metal sheet lamination, pipe network and equipment housing.
(2) Neutral weather resistant adhesive is suitable for weatherproof sealing of various curtain walls, especially recommended for weatherproof sealing of glass curtain wall, aluminum-plastic panel curtain wall and stone dry hanging; 2, metal, glass, aluminum, ceramic tile, plexiglass, coated glass joint seal; 3, concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum surface joint seal. Primer is not required in most cases.
(3) Silicone structural adhesive is mainly used for structural or non-structural bonding assembly between metal and glass curtain walls. 2, it can directly connect the glass and the surface of the metal component to form a single assembly component, to meet the curtain wall design requirements of the full or half hidden frame. 3. Structural bonding and sealing of insulating glass. All kinds of silicone glass glue will be subject to the following restrictions when used: 1, long-term immersion in the place should not be constructed; 2, do not dissolve the material that oozes grease, plasticizer or solvent; 3, frost or wet surface can not be bonded; 4, completely closed place can not be cured; 5, the substrate surface is not clean or firm. Acid glass glue has the following restrictions: Acid silicone glass adhesives will corrode or fail to bond copper, brass (and other copper alloys), magnesium, zinc, electroplated metals (and other zinc alloys), At the same time, it is recommended not to use acid glass glue on the material made of brick and stone and the matrix of iron carbide, and the use of this product on the material made of methyl isocrotonate, polycarbonate, polypropylene, polyethylene and polytetrafluoroethylene will not obtain good bonding effect and good compatibility. Joints that move more than 25% of the joint width are not suitable for acid glass glue, do not use ordinary acid glass glue on structural glass, in addition, acid glass glue should not be used in places where there is abrasion and will produce substantial drawbacks. The surface temperature of the substrate of silicone acid rubber exceeds 40℃.
