Products 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.
