Glass & Metal Silicone Sealant OLV528

1, Glass & Metal Silicone Sealant
2, excellent weatherability, anti-UV, anti-ozone and waterproof
3, seal on most materials
Description:
OLV528 Glass & Metal Silicone Sealant is a one part, neutral cure, high performance neutral cure silicone sealant designed for a wide range of glazing, weatherproof seal on most common building materials (not including copper). It has excellent primerless adhesion to most construction materials.

Main purposes:
1. Weatherproofing sealing in curtain wall;
2. Joint-sealing in day lighting glass;
3. Sealing plated glass;
4. Sealing various glass, doors and windows.

Characteristics:
1. Transparent neutral silicone specially for building, one-component, having very good performance in construction;
2. Excellent weatherability, anti-UV, anti-ozone and waterproofing;
3. Excellent adhesion to most building material, without a need for primer.

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. Cant be used if the temperature is below 4°C or above 50°C on the surface of the material.

Shelf life: 9 months if keep sealing, and stored below 27
