Different uses
1. Weathering glue: Mainly used for weathering sealing of various glass curtain walls, such as weathering sealing of metal (aluminum plate) and enamel curtain walls; joint sealing of concrete, metal, etc. and roof building joint sealing, etc. It is often used in places with higher requirements in engineering occasions, such as sealing gaps between metal and concrete building walls, sealing glass curtain walls, etc.
2. Structural glue: Suitable for bonding structural parts that bear strong forces, and can be used for bonding between the same materials or different materials such as metal, ceramics, plastics, rubber, wood, hollow glass, etc., and can partially replace traditional connection forms such as welding, riveting, and bolting. It is widely used in engineering, mainly for the reinforcement, anchoring, bonding, and repair of components, such as bonding steel, bonding carbon fiber, planting steel bars, crack reinforcement, sealing, hole repair, spike pasting, surface protection, concrete bonding, etc.; it is also used for the metal and glass structure or non-structural bonding assembly of glass curtain walls, which can directly connect the glass to the surface of metal components to form a single assembly component, meet the design requirements of fully hidden or semi-hidden frame curtain walls, and can also be used for the structural bonding and sealing of hollow glass.
3. Sealant: Mainly used to fill the configuration gap to play a sealing role. It can be used for various joints that need waterproofing, including exterior wall filling and structure, glass stone prefabricated panels and curtain walls, kitchen and bathroom sanitary ware joints, etc., as well as various joints that need airtightness, including air conditioning pipes, doors and windows, etc., divided into stone sealants, mildew-proof sealants, fire-proof sealants, pipe sealants, etc.
