Sealant bridge road caulking application
There are one-component and two-component. Modified silicone sealant specially designed for long-term weather-resistant sealing of expansion joints, shrinkage joints and longitudinal joints of airport runways, highways, tunnels, bridges and other concrete or asphalt pavements, with low modulus and high displacement characteristics, Adapt to the displacement of concrete joints.
Seam sealing for airports, highways, and high-speed rail lines;For joint and grouting sealing of other concrete pavements,For the sealing of subway engineering, tunnels, bridges and other projects,Used for water conservancy projects, reservoir dam caulking and waterproofing;Roof caulking and waterproofing for industrial and civil buildings.
It is easy to use and has good extrudability within the usual construction temperature range,No primer required, chemically compatible with concrete, and chemically bonded to concrete,Excellent aging resistance, will not be damaged by sunlight, rain and snow, ultraviolet rays, ozone; excellent high and low temperature resistance, the cured rubber strip has excellent performance at -40 ℃ ~ 120 ℃.High displacement capacity: with the expansion and shear deformation of concrete joints, the colloid itself will not be damaged,Low modulus: low stress generated during passive deformation to ensure that the concrete surface is not damaged,High elastic recovery ability: It can reciprocate and follow the seam movement, with fast response, fast recovery and small deformation.
