Products Description
Road and Bridge Expansion Joint Sealant Filler
A fast-curing, one part flexible sealant designed to provide effective sealing of construction and expansion joints on concrete,stone, brick and other surfaces. This solvent-free material is a cost-effective and high performance alternative to conventional mastics and sealants, providing joints with up to 25% flexibility and outstanding weather and chemical resistance. It does not equire any hot work and cures quickly, ensuring a safe and easy application

7,Easy to mix and apply manually with no specialist tools required
8,Excellent adhesion to surfaces including concrete, brick, stone and steel
9,Single-component packaging, easy to use, and good extrudability within the usual construction temperature range;
10, No primer is required, it is chemically compatible with concrete, and has a firm chemical bond to concrete;
11,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;
12,High displacement ability: With the expansion and shear deformation of the concrete joints, the colloid itself will not be destroyed;
13,Low modulus: low stress generated during passive deformation to ensure that the concrete surface is not damaged;
14, High elastic recovery ability: It can reciprocate and follow the seam movement, fast response, quick recovery, and small permanent deformation.

Operation Process
1. Cutting the construction joint: use a cutting machine to cut the construction joint according to the specifications, use a blow dryer, brush, spatula and other tools to remove the dust and sundries in the joint, and let it dry fully; in order to improve the bonding strength, brush the primer.
2. Laying cushion material: Lay a polyethylene foam strip that is slightly larger than the gap in the seam, with a depth of 8mm or more.
3. Glue filling liquid: Put the self-leveling glue into the filling equipment, insert the hose into the bottom of the seam and inject the caulking glue into the seam; put the paste-like glue into the glue gun, the glue nozzle goes deep into the gap, squeeze the glue and smooth it.
4. Leave a gap: Because the gap will expand and contract with heat, the surface of the caulking glue should be about 2mm lower than the road surface after construction.
5. Curing for at least 5 hours after construction, and the period of loss of adhesion will be exceeded.
