ZQ-688 Neutral Silicone Weathering Sealant

ZQ-688 neutral silicone weather resistant sealant is a single component, neutral cured, and has good adhesion. It can be extruded and used under a wide range of climatic conditions, and quickly reacts with moisture in the air. It solidifies into a durable, high-performance, and highly deformable silicone sealant, which can resist natural corrosion such as oxygen odor, ultraviolet radiation, rainwater, frost, etc. It has excellent adhesive properties for the vast majority of building materials.

Main Configuration

1、 Product performance:

ZQ-688 neutral silicone weather resistant sealant is a single component, neutral cured, and has good adhesion. It can be extruded and used under a wide range of climatic conditions, and quickly reacts with moisture in the air. It solidifies into a durable, high-performance, and highly deformable silicone sealant, which can resist natural corrosion such as oxygen odor, ultraviolet radiation, rainwater, frost, etc. It has excellent adhesive properties for the vast majority of building materials.

2、 Performance characteristics:

1. Excellent adhesion, for most building materials such as glass, coated glass, and painted metal materials, no primer is required.

2. Neutral curing, suitable for most building materials without adverse reactions or corrosive effects.

3. Excellent weather resistance and aging performance.

4. No sagging phenomenon, can be used for vertical interface construction

5. Single component, easy to construct.

3、 Main purpose:

Suitable for sealing general glass, aluminum, ceramic tiles, wood, and some plastics. Expansion joint interface of precast concrete, cement brick, brick structure, coated glass, galvanized steel plate, zinc aluminum steel plate.

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. The surface that needs to be painted may crack or peel off.

7. Places susceptible to wear or physical damage.

8. Will come into direct contact with the surface of food.

7、 Storage period: 

This product is stored in a cool and dry place at 28 ℃, with a shelf life of 12 months.
