Performance Characteristics:
•One-component, translucent, easy to use, with good workability. Apply directly with a caulking gun.
•Non-oily, neutral curing, non-corrosive to building materials such as coated glass and most metals.
•Excellent aging resistance, UV resistance, ozone resistance, and water resistance.
•Excellent high and low-temperature resistance: After curing, it does not become brittle, harden, or crack at -50°C, and does not soften or degrade at 150°C, maintaining good strength and elasticity.
•Excellent adhesion to most building materials.
•Good compatibility with other neutral silicone sealants.
SMT Z0T is a one-component, neutral room-temperature curing silicone elastic sealant. It features excellent weather resistance and adhesion. It is non-corrosive to most building materials (except copper) and bonds well, making it an ideal waterproof sealing material for building door and window installation.
Application Areas
- Installation sealing for various building doors, windows, and window glass.
- Sealing, bonding, and repairing other building materials such as metal, tiles, and marble.
- Weatherproof sealing for canopies, skylights, and exterior curtain walls.
- Interior general sealing.
Package
- This product is available in cartridges 300ml or sausages 590ml. Custom packaging quantities may also be available upon request.

Before application:
- Conduct compatibility tests between the sealant and contacting materials, as well as adhesion tests with the intended substrates before application.
Construction Method:
- Application surfaces must be clean, dry, and free from contaminants.
- Place the cartridge into a suitable caulking gun. Cut the nozzle according to the joint width. Extrude the sealant into the joint, ensuring it makes full contact with both sides of the joint.
- Tool the sealant firmly to ensure adhesion and remove any excess material.
- Do not use as a structural sealant.
- Not suitable for use on steel or polycarbonate materials.
- Not recommended for use in airtight spaces, as the sealant requires moisture from the air to cure.
- Do not apply when the material surface temperature is below 5°C or above 40°C.
- Do not use on frosty or damp surfaces.
- Do not use in areas of continuous water immersion or perpetual dampness.
- Avoid contact with rubber materials (e.g., gaskets, rubber spacers) to prevent yellowing.
- Avoid contact with acidic or alkaline substances (e.g., exterior wall cleaning solutions) to prevent discoloration.
- Application in a well-ventilated area is recommended. In case of skin contact, wipe off immediately and rinse thoroughly with water and seek medical attention if necessary.
- Ambient temperature and humidity affect the working time (tack-free time) and curing speed. Monitor environmental changes before application and adjust or control accordingly.
- Do not use on materials that may exude oils, plasticizers, or solvents, such as surfaces of oil-impregnated wood.
- Use the product within its shelf life. Do not use expired product.
- Strictly follow the procedures established during adhesion testing.
- The product releases trace chemicals during curing. Ensure adequate ventilation in the workspace. It is non-toxic after curing.
- Keep out of reach of children.
