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.

Heat resistant products for fireplaces and stoves are many and varied, made to suit specific conditions. The products needed will vary based on whether the application is an open fire, free standing stove, or cassette fireplace.
Fire bricks, or refractory bricks, are used to line kilns, furnaces, and fireplaces. These bricks are made to withstand high temperatures, and they also have low thermal conductivity for energy savings. For applications typical in homes, such as natural gas fireplaces, more porous bricks can be used instead of the dense bricks used in wood-fired kilns or furnaces. The more porous bricks are much lighter and insulate better than dense bricks due to the tiny air pockets located throughout.
With open fires that use gas or solid fuel, a product called fire cement can be used to do small repairs to joints and cracks. Larger repairs can be done using fireplaace render or heatproof screed, a products that can withstand very high temperatures. If you need to fix tiles in part of your fireplace exposed to heat, you can use heat resistant tile adhesive.
If you are building a new fireplace or opening a chimney breast to create one, you can line the opening with fire bricks set in place with heatproof mortar. The mortar joints should be thin: 3 to 5 mm. Generally speaking, 10 kg of heatproof mortar can be used to place 100 standard sized fire bricks. Alternately, you can render over the existing brickwork with Fireplace Render to a thickness of approximately one inch. Heatproof Screed can also be used to create a base for the fire area. Free standing stoves can be lined with Fireplace Render as well.
Cassette fires (sometimes called “hole in the wall” fires) should have the area around the fire opening lined with heat resistant plaster that is made just for these kinds of fireplaces. Heat Resistant Plater is made to go onto Fireplace Render. This can be applied up to 5 mm thick.
You can also obtain a number of other heat resistant products for fireplaces. Special mortars and adhesives with high levels of silica are made for use with chamotte bricks, ceramic fiber, and insulating bricks. High alumina refractory mortars used with high aluminum refractory bricks are also available. The cements and mortars with the highest alumina content are also suitable with mag-chrome or magnesite bricks.
Premium fire cements come in beige or black and can be used for a number of applications domestically as well as industrially. Fire cement can be used in fireplace repairs, and in the assembly of cast iron stoves.
