Characteristics

1. Acetic cured, RTV, one component;
2. Easy to use, fast curing;
3. Excellent resistance with water, weather;
4. Excellent resistance with huge temperature changing from -20°C to 343°C;
5. Density: 1.01g/cm³;
6. Tack-Free Time: 3~6min; Extrusion: 600ml/min.

Typical Uses

1. High temperature situations, such as fireplace frames.
2. Sealant joints between most non-porous materials such as glass, aluminum, metal and metal alloys.
3. Typical applications including sealing engine parts,gasket,gears and appliances.

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℃ or above 50℃on the surface of the material.

Shelf life

12 months if keep sealing, and stored below 27℃in cool, dry place after the date of production.

Volume: 300ml
