MS (modified silicone) road and Bridge Caulking Sealant is a new type of oily single-component cold caulking product developed by Shengqun New Material Technology Co., Ltd. with independent property rights. It is suitable for repairing asphalt pavement, cement pavement, airport pavement and airport expansion joint, with simple construction and cost saving.
It has the following superior product features:
1. Single-component packaging, easy to use, and good extrudability within the usual construction temperature range;
2. No primer is required, it is chemically compatible with concrete, and has a firm chemical bond to concrete;
3. Excellent aging resistance, will not be damaged by sunlight, rain, snow, ultraviolet rays, and ozone; excellent resistance to high and low temperatures, and the cured adhesive strip has excellent performance at -40°C to 120°C;
4. High displacement ability: With the expansion and shear deformation of the concrete joints, the colloid itself will not be destroyed;
5. Low modulus: low stress generated during passive deformation to ensure that the concrete surface is not damaged;
6. High elastic recovery ability: It can reciprocate and follow the seam movement, fast response, quick recovery, and small permanent deformation.
1. Used for seam sealing of airports, highways, and high-speed rail lines.
2. Used to seal the joints and grouting joints of other concrete pavements.
3. Used for sealing of subway projects, tunnels, bridges and other projects.
4. Used for caulking and waterproofing of water conservancy projects and reservoir dams.
5. Used for roof caulking waterproofing of industrial and civil buildings.
