Weather-resistant adhesive is a one-component, neutral curing, silicone sealant specially designed for various weatherproof seals on curtain walls. It has excellent weather resistance. After artificial accelerated weathering aging test, the physical and chemical properties of the sealant have not changed significantly. Use the glue gun to squeeze the glue from the sealant cylinder into the seams that need to be sealed. The sealant absorbs the moisture in the air at room temperature and solidifies into an elastomer to form an effective seal.


Advantages of weathering glue


1, single component, easy to use, good extrudability and thixotropy in the temperature range of 4 ℃ ~ +40 ℃, can be directly applied with a glue gun extrusion;

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

3. The displacement capacity reaches 20, which can maintain the same performance for normal expansion and contraction of the curtain wall and play an effective sealing role;

4. Excellent weathering resistance, ageing resistance, UV resistance, ozone resistance, and water resistance;

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

6, has excellent adhesion, after curing, it forms a strong bond with most building materials without the need for primer coating;

7, has good compatibility with other neutral silicone glue.

Uses of weathering glue

1. Weather-resistant seal for various glass curtain walls;

2. Used for weather-resistant sealing of metal (aluminum sheet) and enamel curtain wall;

3. Used to seal the joints of concrete, metal, etc .;

4, roof construction joints sealed.

The difference between structural rubber and weathering rubber

First, different uses

Weathering glue

1. Suitable for weatherproof sealing of various curtain walls, especially recommended for weatherproof sealing of glass curtain wall, aluminum-plastic panel curtain wall, and stone dry hanging.

2. Seal the joints between metal, glass, aluminum, ceramic tile, plexiglass, and coated glass.

3. Seal the joints on the surface of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. In most cases, no primer is required.

Structural glue

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

2. It can connect glass directly to the surface of metal components to form a single assembly component, which meets the design requirements of curtain walls with full or semi-hidden frames.

3. Structural adhesive seal of insulating glass.

Where it works

Weather-resistant sealant is mainly used for sealing and filling the gaps between materials and waterproof sealing of joints; while structural adhesive is mainly used for the bonding of structural and non-structural assembly of various curtain walls. The two have different functions.

Third, the bonding performance

1. Weather-resistant sealant can also be said to be a general-purpose adhesive, mainly with extreme weather such as UV resistance, acid rain, and snow. Weathering glue's displacement capacity (explained as elasticity) is higher than structural glue.

2. In addition to the characteristics of weather-resistant sealants, silicone structural adhesives also have stronger bonding properties than weather-resistant sealants, which are mainly manifested in tear resistance, elongation at break, tensile strength, and tensile strength. Mainly used in prestressed places. The modulus, hardness, strength and price of structural rubber are higher than those of weathering rubber of the same grade.

Summary: The weather resistance of structural adhesives is as good as or better than weather resistant adhesives, because the weather resistance of structural adhesives is related to safety. If the aging is fast and the glass falls, the consequences are very serious. Glue), will not age in the natural environment. Weathering rubber does not involve safety. The result of failure is generally water leakage and air leakage. Therefore, there are more types of weathering rubber, including polyurethane, polysulfide, acrylic, etc., but the weather resistance is still the best.
