    The product is cured for 21 days at a humidity of 50±5% and a temperature of 23±2°C.

    Main features:
    1. Neutral curing, suitable for most building materials without adverse reactions or corrosion.
    2. Excellent adhesion, no need to use primer for most building materials such as glass, coated glass, painted metal.
    3. Excellent weather resistance and aging performance.
    4. Single component, easy to construct.
    5. No vertical flow phenomenon, can be used for vertical interface construction.

    Use restrictions:Use restrictions: 

    1. Frosting the wet surface.
    2. The surface to be painted is required because the paint will crack or peel off.
    3. All materials that will ooze grease, plasticizers or solvents, such as oil-impregnated wood, oil-bottomed steel seams and some unvulcanized or partially vulcanized     rubber lining and tape.
    4. Locations that are not ventilated (silicone gels need to be cured by moisture in the atmosphere).
    5. Will directly touch the surface of the food.
    6. Continuous immersion environment.
    7. The place where the ground is wet all year round.
    8. Places subject to wear or physical damage.

    Basic use:

      1. Installation and sealing of doors, windows and doors of various buildings.

      2. Sealing, bonding and repairing of other building materials.

    Color and packaging:

      Available in black, white, grey, and transparent, with 300ML plastic hose.

    Storage and expiration date:

      Non-dangerous goods, please store in a cool dry place below 27 °C, valid for 12 months.

    Construction method:

    1. Remove all grease, dust, moisture, surface dirt, old sealant, assembly accessories and protective coatings and other    
    contaminants left in the interface and assembly recess. Glass. Metal must be cleaned with solvent according to two cloth 
    cleaning methods. The selected solvent is xylene or methyl ethyl ketone solvent.
     2. Install gasket material or interface filler, pad spacer and tape as required. The LZ801 neutral silicone weatherproof sealant is continuously squeezed in and filled up the interface. When the sealing surface has not been skinned, the sealant is flattened to the gasket material and the interface surface with an appropriate force. The finishing process must be done after the sealant is applied and before the surface of the glue has not been skinned. It is recommended to use a convex tool to hold the rubber surface into a concave shape. Do not use soap and water as an auxiliary material for dressing. Immediately after the trimming is completed, the cover will be torn off. In the case of outdoor temperatures as low as -25 ° C, building silicone weatherproof sealants can still be extruded on clean, dry and frost-free surfaces, uncured sealants are absolutely not allowed and non-abrasive surfaces, such as Polished marble, metal or glass contact, because these excess sealants cannot be completely removed with organic or chlorinated solvents, these surfaces must be covered, or extra care must be taken before applying the sealant to prevent sealant and these Surface contact, once the uncured sealant contacts these surfaces, it will leave a film on the surface, which will affect the unique aesthetic surface of the substrate, if not pay attention to the uncured sealant When in contact with the surface of the interface, it must be removed with toluene, xylene or methyl ethyl ketone solvent before the sealant has been cured. When using flammable solvents, special precautions should be observed.
     3. It is recommended to carry out curing in a high temperature and humidity environment to facilitate the deep curing of the sealant.
