OLV768 Big Glass Silicone Glazing Sealant

Short Description:

OLV768 Big Glass Silicone Glazing Sealant is one-component, acetoxy cure, high quality silicone sealant designed for big glass and other general purpose glazing and waterproofing application.
It’s a non-toxic, solvent-free silicone sealant for use in aquarium construction and glazing applications. It’s a high-quality acetic curing system based silicone sealant featuring excellent adhesion to glass and many other non-porous surfaces.
It has high tensile strength and good elasticity, excellent weatherability, stability, waterproof and good adhesion to most construction materials without a primer. It has good features as follow: a. easily use: can extrude in any time; b. acetic cure: To float glass, anodized aluminum material needn’t base coating, has a strong felt power ;c. high modulus , as cured, it can bear joint movement capability of ±20%.

    Main purposes

    1.  Big panel glass seal;
    2.  Skylights, canopies and general glazing;
    3.  Aquarium and general decorative usages;
    4.  Many other industry applications.


    1. It is RTV-1, acetoxy, curing at room temperature, high intensity, medium modulus, fast curing, high intensity and good elasticity, optimum adhesion to glass;
    2. Excellent weathering resistance and durability;
    3. Exceeding 60 colors could be chosen, other colors could be customized;
    4. Other building construction applications.


    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;
    5. Construction and repair of aquariums and many glass structures;
    6. Suitable on glass/aluminum structures;
    7. Glazing on aluminum frames and shop displays;
    8. Sealing of windows and doors.


    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 27℃ in cool, dry place after the date of production.
