What is the difference between weatherproof silicone sealant and structural silicone sealant?

 

Structural Silicone Sealant:

The structural silicone sealant has high tensile strength, elongation rate, and viscosity. It must pass the 1MG GB 16776-2005 specification. The compression strength of the structural silicone sealant must be greater than 65 MPa, the steel–steel forward tensile bonding strength b must be greater than 30 MPa, and the shear strength must be greater than 18 MPa.

The properties of structural silicone sealant are as follows:

1. It is suited for large-scale curtain wall structural adhesion

2. Provide a safety factor of more than 8 times

4. Excellent weather resistance, can function for 50 years under typical temperature conditions

3. Neutral curing, non-corrosive to metal and coated glass


Weatherproof Silicone Sealant:

Weather resistance silicone sealant must pass a purposely accelerated weathering test, demonstrating that the sealant is unaffected by sunshine, rain, snow, ozone, and temperatures ranging from -40°C to 150°C.

The following are the functions of waterproof silicone sealant:

1. It's applied for curtain walls, outside walls, interior decorating bonding, and joints, among other things.

2. Non-corrosive to metal, tiles, granite, stone, and glass due to neutral curing

3. Long-lasting work that can withstand changes in the weather or temperature.
