1、 Product performance:

ZQ-655 silicone structural sealant is a medium to high modulus, neutral room temperature curing organic silicone elastic sealant specially designed for structural assembly. By reacting with moisture in the air to form elastic rubber, it has excellent weather resistance and resistance to sunlight, rain, ice, snow, and ozone. Even in extreme temperature environments (-40~150 ℃), it will not cause adverse effects.

2、 Performance characteristics:

1. For most building materials such as glass, coated glass, anodized aluminum, granite, and painted metal materials, there is no need to use primer to achieve superior adhesion.

2. Neutral curing, non corrosive.

3. After curing, a strong and elastic silicone rubber is formed, which will not undergo significant changes due to aging and exposure to the atmosphere. The sealant still maintains its waterproof and weather resistance characteristics.

4. Single component, easy to construct.

3、 Main purpose:

1. Structural glass curtain wall.

2. Manufacturing multi-layer insulating glass.

3. Used for edge composite sealant.

4、 Technical parameters:

Note: The following data is for reference only and is not recommended for specification development. The performance of each type of silicone is subject to the actual testing report.

5、 Construction summary: 

1. The surface of the substrate for sealant bonding must be clean, dry, and free from dust, oil, and moisture.

2. Clean and dry the surface of the substrate with a clean, lint-free cotton white cloth and a solvent of toluene or acetone to remove stains, and inject glue within one hour.

3. Ensure that the adhesive is fully applied to the joint without gaps, and modify it before the adhesive solidifies without safely isolating air.

4. Before use, on-site substrate adhesion and compatibility tests as well as user satisfaction tests must be conducted.

5. Restricted use in areas that are constantly damp or soaked for a long time.

6、 Usage restrictions:

1. All materials that can exude grease, plasticizers, or solvents, such as oiled wood, oil bottomed steel plate joints, and certain unvulcanized or partially vulcanized rubber linings and tapes.

2. A tightly ventilated area (silicone adhesive needs to be cured by moisture in the atmosphere).

3. Frosted and damp surfaces.

4. Continuous immersion environment.

5. A damp place underground all year round.

6. Places susceptible to wear or physical damage.

7. Restricted use in areas that are constantly damp or soaked for a long time.

7、 Storage period: 

This product is stored in a cool and dry place at 28 ℃, with a shelf life of 1 year.

8、 Executive standards:
