AG-668 Acetoxy Multi-Purpose Silicone Sealant Description: AG-668 Multi-Purpose Sealant is one-component, acetoxy cure, high quality silicone sealant designed for general purpose glazing and waterproofing application. It has high tensile strength and good elasticity, excellent weatherability, waterproof and good adhesion to most construction materials. Main purposes: 1. For windows glazing, door frames, display cupboards,all kinds of indoors and outdoors glass engineering; 2. For sealing glass, aluminum alloy and ceramic; 3. For other general waterproof and sealing purpose. Characteristics: 1. One-component, acetic-cured, RTV, high tensile strength and good elasticity; 2. Easy to use, fast curing, durable, and excellent weatherability; 3. Good adhesion to most building materials; 4. Colors include clear, white, grey, bronze, and black, or other colors as per customers’ requirements. Application: 1. Clean with solvents such as toluene or acetone to keep the substrate surfaces completely clean and dry; 2. For better appearance cover outside of joint areas with masking taps before application; 3. Cut nozzle to desired size and extrudes sealant to joint areas; 4. Tool immediately after sealant application and remove masking tape before sealant skins. Limitations: 1. Unsuitable for curtain wall structural adhesive; 2. Unsuitable for the airproof location, because it is required to absorb moisture in air to cure for the sealant; 3. Unsuitable for the frosty or moist surface; 4. Unsuitable for the continually soggy place; 5. Can’t be used if the temperature is below 4°C or above 50°C on the surface of the material.
