Main purposes

1. Sealing for coated glass, the materials with polycarbonate, large glass;
2. Sealing for windows and doors;
3. Excellent adhesive to most common building material.

Characteristics

1. One-part; Room temperature; Neutral curing silicone sealant;
2. Non-corrosive to marble, coated glass, concrete, metal (not including copper) etc;
3. Quickly speed of curing, excellent adhesion, excellent displacement capability;
4. Good compatibility with other neutral silicone sealants.

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.

Shelf life: 12 months if keep sealing, and stored below 27⁰C in cool, dry place after the date of production.
Volume: 300ml
