Silicone glass adhesive is a kind of silicone products. Ketone glass adhesive is divided into two kinds, one component and two components, which are mainly used for sealing hollow glass. Two component silicone glass rubber is room temperature vulcanized silicone rubber 107 It is a two-component sealant with room temperature vulcanization of metal oxide and methyl silicone oil 201 as the main agent. After curing, the sealant has excellent weather resistance and UV resistance, high and low temperature resistance and aging resistance, high bonding strength, good adhesion to glass and aluminum alloy, and is mainly used for the second sealing of hollow glass. Today, we will discuss the difference between weatherproof sealant and structural sealant. Why is structural sealant more expensive than sealant?
Weatherproof sealant
Weatherproof sealant
1. It is suitable for all kinds of curtain wall weatherproof seal, especially recommended for glass curtain wall, aluminum plastic panel curtain wall, stone dry hanging weatherproof seal.
2. Joint sealing among metal, glass, aluminum, ceramic tile, plexiglass and coated glass.
2. Joint sealing among metal, glass, aluminum, ceramic tile, plexiglass and coated glass.
3. Joint sealing of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum surfaces, in most cases without primer.
4. It has excellent weather resistance such as ozone resistance and ultraviolet resistance, which gives it a long service life.
5. It is mainly used for structural or non structural adhesive assembly between metal and glass of glass curtain wall.
6. It can directly connect the glass and the metal component surface to form a single assembly component, meeting the curtain wall design requirements of full hidden or semi hidden frame.
7. Structural bonding and sealing of insulating glass.
8. It is suitable for sealing porous stone, laminated glass, hollow glass, mirror glass, coated glass, zinc, copper and iron materials.
Weatherproof sealant is mainly used for sealing and caulking between materials, while structural adhesive is mainly used for bonding, and they are not used in one place.
Silicone structural adhesive1. Weather resistant sealant can also be said to be a general-purpose adhesive, mainly with UV resistance, acid rain, snow and other extreme weather.
2. In addition to the characteristics of weather resistant sealant, silicone structural sealant also has stronger bonding performance than weather resistant sealant, mainly in tear strength, fracture elongation, tensile strength is relatively strong, tensile strength is mainly used in the place of pre stress.
3. Structural adhesive is used for structural and non structural assembly and bonding of various curtain walls, while weatherproof adhesive is mainly used for waterproof sealing of joints.
4. The modulus, hardness, strength and price of the structural adhesive are higher than those of the same grade, but the elasticity of the weather resistant adhesive is higher than that of the structural adhesive.
Weatherproof sealant can be said to be a general-purpose adhesive. Its main function is to keep the sealing state in extreme weather such as UV resistance, acid rain, snow, etc! In addition to the sealing properties of sealant, structural adhesive also has stronger adhesion than weather resistant adhesive, mainly in tear strength, fracture elongation, tensile strength, etc., so relatively speaking, structural adhesive will be more expensive than sealant!
