The adhesive sealant has the advantages of high strength, peeling resistance, impact resistance and simple construction process. It is used for bonding metal, ceramic, plastic, rubber, wood and other same materials or different materials. It can partly replace welding, riveting, bolt connection and other traditional connection forms. The stress distribution of the joint surface is uniform, and there is no thermal effect and deformation on the parts.

In engineering, structural adhesive is widely used, mainly for component reinforcement, anchoring, bonding, repair, etc.; such as steel bonding, carbon fiber bonding, steel planting, crack reinforcement, sealing, hole repair, spike bonding, surface protection, concrete bonding, etc.

Weatherproof adhesive is a one component, neutral curing silicone sealant specially designed for weatherproof sealing of various curtain walls. It has excellent weatherproof performance. After artificial accelerated climate aging test, the physical and chemical properties of the sealant have no obvious change. When in use, the glue is squeezed from the sealant cylinder to the joint to be sealed by the glue extrusion gun. The sealant absorbs the moisture in the air at room temperature and solidifies into an elastomer to form an effective seal.

Advantages of weather resistant adhesive.

1. Single component, easy to use, with good extrudability and thixotropy in the temperature range of 4 ℃ ~ + 40 ℃. It can be extruded directly with glue gun;

2. Neutral curing, non corrosive to metal, coated glass, concrete, marble, granite and other building materials, so it is widely used;

3. Displacement capacity up to 20, for the normal expansion and shear deformation of the curtain wall, the product can maintain the same performance and play an effective sealing role;

4. Excellent weather aging resistance, aging resistance, UV resistance, ozone resistance and water resistance;

5. Excellent high and low temperature resistance. After curing, it will not become brittle, harden or crack at - 30 ℃ and will not soften or degrade at + 90 ℃. It always keeps good elasticity;

6. It has excellent adhesiveness and forms a strong bond with most building materials after curing without using primer;

7. It has good compatibility with other neutral silicone adhesives.
