SV-GT2000 High-speed rail subway silicone sealant is a one-component, low modulus, neutral curing adhesive. For most of the stone, ceramic and cement components, can produce excellent adhesion
(1) easy to use: can be used at any time out;
(2) excellent thixotropy and extrusion, at any temperature (-40 ℃ to 100 ℃) can be extruded;
(3) good adhesion, the stone, ceramics and cement components and other building materials with excellent adhesion properties; no pollution of the porous material;
(4) excellent weather resistance, aging performance, excellent tensile and compression resilience, can carry ± 30% displacement capacity;
(5) neutral curing, stone, cement and other building materials without corrosive, to overcome the shortcomings of acid corrosion material.
(6) base modulus: passive deformation occurs when the role of moderate stress on the concrete substrate to ensure that the concrete surface is not destroyed;
(7) high elasticity high recovery capacity: can be repeated from the seams with the movement, fast response fast response, permanent deformation of small.
1.For high-speed rail track, airport runway, highway irrigation joints sealed, can withstand large displacement;
2.Can also be used for other concrete pavement sealing, subway engineering, tunnels, bridges and other projects sealed.

Fire prevention, health and safety
(1) the sv-gt1800 non-roast-specific silicone sealant is a non-combustible product
(2) prevent skin and eyes from direct contact; If there is an accident, please contact the doctor
(3) if the skin touches, remove contaminated clothing and clean the skin thoroughly for 15 minutes or see a doctor
The construction of the
(1) basic cleaning
Remove the foam in seam.
(2) the processing interface
For expansion joint on the side of the concrete bonding surface processing, sewing inside of the remaining oil, curing agent.
(3) the side closed
Use foam board or board, adhesive tape and so on will be closed on both sides of the expansion joints, vaseline and other auxiliary seal are available, and to ensure no leakage on material conditions.
(4) the orbital protective
In the expansion joint on both sides of the road bed board concrete protective tape, paste against pollution of the road bed board concrete construction process.
(5) the bottom coating liquid
For a handful of base material, sometimes coat liquid must be used to enhance the cohesiveness of the colloid and interface.Bottom coating fluid sealant should be applied in the manufacturer’s recommendations and process.
Within 30 minutes after the glue with width gap slightly narrower than the surface of the rubber scraper pressure blowing gently again, so that gap within the adhesive can form a u-shaped cross section, it is helpful to reduce the rains washed out of glue and concrete bonding surface damage, extend the lifespan of the glue, and can effectively remove escaping bubbles in the glue.
After the completion of the sealing, away construction debris;After being table dry sealing materials, removable protective tape;Sealing material work, after dismantling closed on both sides, clean up the scene.
Construction is completed, to curing adhesive for at least 24 hours, any water at any time during a tournament is strictly forbidden to enter.If encounter the weather forecast it will rain should stop in advance of construction.
