Main purposes

1.Flame resistance, waterproof and moisture proof sealing for hotel, theatre and other public places;
2.Flame resistance, installing and sealing for all kinds of windows and doors;
3.Adhesion and sealing for all kinds of flameproof windows and doors, flame resistance sealing for curtain wall;
4.Flame resistance sealing for electronic installation;
5.Many other building or industrial purposes.

Characteristics

1.OLV507 is RTV-1 neutral curing at room temperature and medium modulus flame resistant silicone sealant;
2.Outstanding flame resistance,FV-0(GB/T 2408),no fume and toxic gas released when fired;
3.Excellent resistance to weather and ultraviolet radiation;
4.Excellent adhesion to most common building material without priming in general condition;
5.Neutral curing , non-corrosive to the building materials of metal , coated glass , concrete , ceramic , marble , granite , etc;
6.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: GB/T 14683-2003 ASTMC 920 GB/T2408 FV-0
