What Are The Advantages Of Weather Proof Silicone Sealant In Terms Of Weather Resistance?

Weathering silicone sealant, also known as silicone sealant, refers to a type of silicone rubber produced mainly from linear polysiloxane. Below is a brief introduction to the advantages of weather proof silicone sealant.

Weather proof silicone sealant is a single component neutral curing silicone weather sealant specifically used for weather sealing of various curtain walls, glass curtain walls, aluminum curtain walls, etc. It has excellent weather resistance. After artificial accelerated aging test, there was no significant change in the physical and chemical properties of the sealant. When using, use a glue gun to squeeze the glue from the sealant barrel into the joint to be sealed. Sealants absorb moisture from the air at room temperature and solidify into elastomers, forming an effective seal. Excellent high and low temperature resistance -50-150 excellent structural strength.

1. Single molecular structure, easy to use, excellent extrudability and ductility at room temperature, and the actual operation of engineering construction can be realized with the extrusion gun;

2. It is non corrosive and has good ductility to building decoration materials such as metal materials, glass, reinforced concrete, natural marble, granite, etc;

3. It has good scalability . After a certain amount of stretching, the performance remains unchanged and has excellent sealing performance.

4. It has the characteristics of oxidation resistance, aging resistance, corrosion resistance, waterproofing, sun protection, and isolation;

5. Heat resistant, not easily deformed, regardless of high temperature, high and low temperature, the physical properties of weather resistant adhesive are consistent.

6. Easy to use and able to connect most building components.

7. Excellent compatibility with other neutral silicone adhesives.

What are the main uses of silicone weather resistant adhesive?

1. Used for various glass coating and wall bonding.

2. Used for bonding metal composite materials with enamel building curtain walls.

3. Bond concrete.

4. Bonding of engineering building roofs.

What is the chemical composition of silicone weather proof sealant?

1. Weather proof silicone sealant refers to a type of silicone rubber produced mainly from linear polysiloxane, also known as silicone sealant. The following content mainly introduces the chemical composition of silicone weather proof sealant.

Compared with other organic sealants (such as polyurethane sealant, acrylic sealant, polysulfide sealant, etc.), its polymer main chain is mainly composed of silicon oxygen silicon bonds. The characteristic of weather resistant silicone sealant is its excellent high and low temperature and weather resistance.

3. According to the types of small molecules released during curing, building silicone weather sealants can be divided into deacetylated and Deamidation types. Silicone acetate weather proof sealant, commonly known as "acid adhesive", has a fast curing speed and good transparency. However, during the curing process, acetic acid is released, which has a pungent odor and is corrosive to metals, coated glass, and some inorganic materials.
