SV – 119 Fire resistant silicone sealant is a one-component, heat resistant and neutral-curing fireproof silicone sealant exhibiting superior performance in applications where sealing openings in walls and floors are needed to control the spread of fire, smoke, toxic gasses, and water during fire conditions.
Where to use
It is an ideal material designed for use in fire-stop systems for through penetrations and joints. This product excels in applications where greater water resistance is required e.g. curtain wall, building facade, expansion/pipe and cable joints.
1. 100% silicone
2. Excellent weatherproofing and waterproofing
3. Low gas transmission rate
4. With highly efficient redundant
- Building fire seam sealed
- Building facade
- cable joints

SV-119 Fire Resistant Silicone Sealant is not applicable to structural assembly. In the following situations are not easy to use:
1, all ooze a grease solvent, plasticizer, or materials, some unvulcanized or part of the vulcanized rubber and adhesive tape, etc.;
2, no ventilation parts (silicone sealant should be in the air moisture curing);
3, long-term immersion, at the age of underground moist environment;
4, paint surface, may should paint film cracking or spalling caused by seal failure;
5, frost or wet surface;
6, the surface of the direct contact with food;
7, easy to place by mechanical wear.
This product material that did not include product safety material safe use instructions. It must be noted:
1. Do not use sealant products in contact with the food, the cosmetics;
2. No curing sealant cannot long time of contact with the skin;
3. If you accidentally make a sealant into eyes, should rinse immediately with plenty of water, and then send for a doctor check;
4. Place the product on children do not touch the place.
The construction of the
Remove all parts retained on interfaces and assembly sag of grease, dirt, moisture, such as surface smudginess travel-weary sealant, 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 specially designed for the matters needing attention. For plastics should follow the guidance of the supplier, choose suitable solvents.
For porous material must adopt grinding, sawing, flushing (water or sand), or clear the above method, make sure the surface is clean, dry and get sealant. Dust and other impurities which use oil free compressed air blowing or vacuum suction.
Use of Siway silicone sealant usually do not need to use coat. If the test need to be used for certain material bonding primer, then pour Siway 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 obturator seats foam foam bars and gathering of loose materials for recommended 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-9900 product packaging head cut into proper glue guns, and will be out of the gate diameter and suitable for building joints, SV-9300 product continuous compacted into construction seam, avoid to produce bubbles. In the surface of the sealant has not yet been crust is the appropriate power will flatten sealant, sealant was then using convex tool concave surface, do not use soap water to repair of auxiliary materials. 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. In the open air under the condition of low – temperature 25 ℃, SV-9900 the playing surface must be dry frost-free. 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.
Repair the sealant
Before the repair damaged interface sealant, should first find out the reason, and then determine the repair methods.
If the original sealant aging;
The deflection of the interface exceeds the capability of the sealant can bear;
Sealant and material bonding interface is bad or incompatible with liner material;
The thickness of the sealant than not appropriate;
May also have many other reasons, the cause must be before they can have
