  • Use restrictions

    Siway SV-888 used in weatherproof silicone sealant is not applicable to structural assembly. In the following situations is unfavorable also use:

    Δ all ooze a grease solvent, plasticizer, or materials, some unvulcanized or part of the vulcanized rubber and adhesive tape, etc.;

    Δ dense airless parts (silicone sealant should be in the air moisture curing);

    Δ submerged for a long time, at the age of underground moist environment;

    Δ paint surface, may be caused by film cracking or spalling seal failure;

    Δ frost or wet surface;

    ΔThe surface of the will direct contact with food;

    Δ easily by mechanical wear and tear;

    Δ fire prevention sealing system;

    Δ material surface temperature below 5 ℃ or more than 40 ℃ unfavorable construction.

    The construction of the

    Surface cleaning

    Remove all parts retained on interfaces and assembly sag of grease, dirt, moisture, travel-weary sealant, such as surface smudginess, fittings and protective coating and other impurities and contaminants.

    Glass, metal, must be based on the two cloth cleaning cleaning with solvent, the selected solvent for methyl ethyl ketone, toluene and xylene, when using the organic solvent shall comply with the special attention. For plastics should follow the guidance of the supplier, choose the appropriate solvent.

    primer

    The use of Siway silicone sealant usually does not need to use primer. If the test need to be used for certain material bonding primer, then pour zhijiang special primer on a not to take off the cloth with soft nap piece of white cloth, wipe to on sealant of a thin layer on the surface, after dry can play sealant.

    cover

    Near the interface parts need to be covered, in order to ensure the sealing line is perfect in good working order. Don’t cover tape will come into contact with is going to hit the surface of the sealant. After the glue, in front of the sealant has not yet been crust, must adjust immediately, after the completion of the renovation work, she immediately to remove cover tape.

    Packing materials

    Opening of poly (amino formic acid ethyl ester or polyethylene foam foam obturator sex bars and polyolefin material is recommended by the liner material. For shallow interface can’t accommodate the bubble stick, can be substituted for polyethylene tape.

    These materials have the effect of prevent sealant triple bond.

     

    The construction application

    In accordance with the instructions, installation gasket material or filler, lining rod spacer and tape. SV-999 product packaging head cut into proper glue guns, and will be out of the gate diameter and suitable for building joints, SV-999 product continuous compacted into construction seam, avoid to produce bubbles. In the sealant surface crust is, with the appropriate power will flatten sealant, sealant, then use convex tool concave surface, do not use soap and water as the auxiliary material modification. After finishing, immediately cover tape torn off. On the glass assembly, according to the bottom of the interface of sealant should be trimmed to bevel, make its not produce water phenomenon. Not curing sealant is absolutely not allowed with an abrasive such as polished marble, metal, glass and other surface contact, because these extra after curing sealant can’t use effective solvent removal, once a contact, will leave a layer of thin film on the surface, and affect the base material peculiar and beautiful, so the surface must be protected with cover tape. If you don’t notice will not curing sealant and interface of the porous material surface contact, must be in before sealant curing, using methyl ethyl ketone, toluene or xylene solvent to remove immediately. In the factory construction, after sealant, should be kept higher environmental temperature and humidity, is helpful for curing sealant.
