The difference between the use of silicone structural sealant and  silicone weather resistant sealant

Weather resistant sealant

1. Suitable for weatherproof sealing of various curtain walls, it is recommended to use  weatherproof sealant  for weatherproof sealing of glass curtain wall, aluminum-plastic panel curtain wall and stone dry hanging;

2.Weather resistant sealant  can be used to seal the joints between metal, glass, aluminum, ceramic tile, plexiglass and coated glass;

3.Weather resistant sealant  can be used to seal the joints between metal, glass, aluminum, ceramic tile, plexiglass and coated glass;

4.Weather resistant sealant  can be used for joint sealing of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum surfaces. Primer is not required in most cases.

Silicone structural adhesive

1.Silicone structural adhesive  is mainly used for structural or non-structural bonding assembly between glass curtain wall metal and glass.

2.Silicone structural adhesive  can connect the glass directly with the surface of the metal component to form a single assembly component, which meets the design requirements of the fully hidden or semi-hidden frame curtain wall.

3.Silicone structural adhesive  can be used for structural bonding and sealing of insulating glass.

The difference between  silicone structural sealant  and  silicone weather resistant sealant:

1.Silicone weather resistant sealant  is mainly used for sealing and caulking between materials, while  silicone structural sealant  is mainly used for bonding, and the two are not used in one place.

2.Silicone structural adhesive  not only has the characteristics of  weather-resistant sealant, but also has stronger bonding properties than  weather-resistant sealant, mainly in tear strength, elongation at break and tensile strength is stronger, tensile strength is mainly used for distressing parts.

3.Structural adhesive  is used for structural and non-structural assembly bonding of various curtain walls, and  weather resistant adhesive  is mainly used for waterproof sealing of joints.

4. The modulus, hardness, strength and price of  structural adhesive  are higher than that of  weather-resistant adhesive  of the same grade, but the elasticity of  weather-resistant adhesive  is higher than that of  structural adhesive.
