Description
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
Key Features
(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.
Basic Application
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.

After our extended snowbird trip down south I like to go over our Cougar fifth wheel trailer with a fine tooth comb looking for defects. This spring I discovered a small leaky seal in one corner of the slide out room. Luckily it hadn’t had a chance to progress too far. Still, though, it had weakened a small area of the floorboard.
I found the leak was caused by a small opening in the external silicone sealant. Silicone caulking will dry out over time leaving openings for water to penetrate. Water had seeped in over time and wetted the floor board making it a bit spongy. Given enough time I’m sure it would have rotted away completely and led to a structural failure of the slide room. Glad I caught it early!
To repair the problem, I first removed the external flange and scraped away the old silicone caulk using a plastic chisel, scotch pad, and my thumbnail. To help loosen up the old caulking, I use a product called “Goo Gone Caulk Remover.” With around a 1/2 hour of effort, I was able to get rid of pretty well all the old silicone. Extremely important as nothing will stick to silicone.
Next, I drove several 1 1/4 inch Teks Screws through the affected board area and into an aluminum beam above it. I made sure the screw was countersunk into the wood as not to catch when the slide is drawn in.
Finally, I reattached the flange and resealed it with a product called SikaFlex 290, a high-end marine grade sealant. I smoothed out the SikaFlex and made a smooth seam using a special caulking tool. The tool comes with multi-sized flexible trowls. Then cleaned up the overflow bits and let cure.
