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.

Hydrophobic nano coatings are achievement of nanotechnology and are available on the market for the last few years.
ULTRA EVER DRY and NEVERWET are the most popular brands you may recognise. And they are doing pretty nice job when comes to surface modification for liquid repelling purpose.
What you seeing now, is a coating having very same properties, but is made with nothing else, but two known for years easy to find at home, inexpensive products – CLEAR LACQUER SPRAY and MULTI SURFACE POLISH – COST €5
The Clear Lacquer goes on first sealing the surface, but also it will act as a binder to bind the top coat layer to the surface – Multi Surface Polish which acts as a hydrophobic agent and is sprayed when clear coat is still wet. This hydrophobic coating needs about an hour to dry.
The reason this works because of the Multi Surface Polish includes an organic hydrophobic compound the Aliphatic Hydrocarbons.
This is an easy inexpensive way to make a hydrophobic coating like “Ultra Ever Dry” or “NeverWet” from products that have been available for decades. It works great!
1. BASE COAT – CLEAR LACQUER AEROSOL – AS A BINDER
Clear Lacquer Spray – perfect binder for our project because of good adherence to almost any surface, thin layer, transparency, and fast drying.
2. TOP COAT – MULTI SURFACE POLISH – HYDROPHOBIC AGENT
Spray Can Ingredients:
Contains 5-15% Aliphatic Hydrocarbons, less than 5% Non Ionic Surfactants,Also contains Perfume, Hexyl Cinnamal, Butylphenyl Methylpropional, Benzyl Salicylate, Preservative Methylisothiazolinone & Methylchloroisothiazolinone
I chose the multi surface polish spray because it includes an organic hydrophobic compound, such as an aliphatic compound or with an alkyl aromatic compound. The non-ionic synthetic organic detergents generally are the condensation products of an organic aliphatic or alkyl aromatic hydrophobic compound.
