Description:

OLV528 Metal & Glass 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: 12 months if keep sealing, and stored below 270C in cool, dry place after the date of production.

Volume: 300ml
