Main purposes

1. Joint sealing for stone curtain wall and cement precast slab;
2. Adhesion and joint sealing for ceramic engineering;
3. Joint sealing between stone and other materials like glass, metal, plastics etc;
4. Many other purposes.

Characteristics

1. OLV1800 is RTV-1,neutral curing at room temperature and medium modulus silicone sealant;
2. No inert low-molecular-weight components like plasticizer in the formula and no pollution to porous materials like marble, granite. Excellent sealing and decoration effects than common silicone sealants and overcome the disadvantage of causing pollution of silicone weatherproofing sealant;
3. Excellent adhesion to all types of marble, granite and cement materials;
4. Excellent resistance to weather and ultraviolet radiation;
5. 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.
Standard: JC/T 883-2001 ASTMC 920
Volume: 300ml
