Sealant for joint filling

Seam sealant

Sealant is compounded from base asphalt, high molecular polymer, modified rock asphalt, anti-slip agents, stabilizers, additives, etc., under specific processing conditions, and is a thermoplastic polymer sealant with strong bonding power. Pavement sealant is also made by combining base asphalt, high molecular polymer, modified rock asphalt, anti-slip agents, stabilizers, additives, etc., under specific processing conditions, and is a thermoplastic polymer sealant with strong bonding power.

Product Features：

①High bonding and flexibility.

② Excellent temperature stability and low-temperature crack resistance.

③ Water resistance and aging resistance.

④ User-friendly and durable, environmentally friendly and energy-saving, effectively extending maintenance cycles and reducing maintenance frequency.

Construction Precautions:

1. Perform the task using a slotting machine, adjusting the slot width according to the crack markings and width.

2. Remove at least 3mm from both sides of the crack to expose the new bonding surface.

3. It is not advisable to perform trenching when the surface layer of asphalt pavement lacks sufficient strength to withstand the cutting impact force of the trenching machine.

4. Heat the potting adhesive to the filling temperature, inject it into the槽 using a pressure nozzle, and ensure the discharge pipe is equipped with a heating function.

5. Sewerage can be done using a needle nozzle, and a sealing layer 5 cm wide can be formed by dragging a small boot on both sides of the crack.
