Siway SV-999 Structural Glazing Silicone Sealant is suitable for the 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;
Δ will direct contact with food;
Δ easily by mechanical wear and tear;
Δ fire sealing system.
Data in this product specification does not include the safe use requirements for product safety information. It must be noted:
Do not use sealant products in contact with the food, the cosmetics;
Not curing sealant cannot long time of contact with the skin;
If you accidentally make a sealant into eyes, must rinse immediately with plenty of water, then please doctor check;
Place the product on children do not touch the place.
Structural interface design
The typical structure of silicone sealant application interface design, the basic design principles include:
Width (only consider wind load) = [the side length (mm) x design wind pressure value (KPa)] / [2 x 200 (KPa)];
Depth (mm) ≥ curtain wall glass relative displacement (mm) / [deformation ability of structural adhesive glue (2 + structure displacement ability)] 1/2;
Structural adhesive width ≥6 mm, or structural adhesive depth ≥ 6 mm, or structural adhesive width or depth of the structural adhesive;
Structural adhesive width and depth ratio must be between 1:1 to 3:1.
The construction of the
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.
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.
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.
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.
