Use a variety of silicone sealant will be subject to the following restrictions: 1, not long-term flooding of local construction; 2, not participating leaking oil, plasticizers or solvents compatibility; 3, frost or wet surfaces can not be adhesion; 4, fully enclosed office can not be cured (silicone required * in the air moisture curing); 5, the substrate surface is not clean or not solid.

    (A), acid glass, plastic and more the following restrictions:

    Acidic silicone sealant will not bond corrosion or copper, brass (and other copper alloys), magnesium, zinc, electroplating metal (and other zinc alloys), and recommended articles made of masonry materials and iron carbide matrix body Do not use acidic glass, plastic, in the methacrylate salts (PLEXIGLAS), polycarbonate, polypropylene, polyethylene, and TEFLON (Teflon, PTFE) materials made using this product can not be good bonding effect and good compatibility. Move more than 25% of the width of the connection joints are not suitable for acidic glass cement, the structure of glass is also better not ordinary glass, plastic acid (acid structure, except rubber), while in the abrasive and the place will have no real disadvantages Acidic plastic glass should be used. Silicone rubber substrate of acid temperature is above 40 ? not construction.

    (B), neutral weather adhesive has the following limitations:

    Neutral weather rubber does not apply to structural glass assembly; substrate surface temperature is above 50 ? not construction.

    (C), silicone rubber has the following limitations:

    Silicone adhesive substrate temperature exceeds 40 ? not construction.
