OLV 507  Neutral Fire Resistant Silicone Sealant

Description: 

OLV507 Fire Resistant Sealant is a one part, neutral cure silicone sealant, specially formulated for applications that require maximum resistance against fire. It has excellent weathering resistance, durability, sealing and excellent adhesive properties.

Cured sealant bonds firmly to many substrates, and gives high performance silicone rubber sealant for fire-resistant applications.

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.
