Single-component polyurethane sealant is a single component that can be cured by reacting with moisture in the air to form a material with strong bonding strength and elastic properties. It is a self-flow normal temperature construction sealing material. It does not require heating and directly fills holes, joints, etc. to play the role of bonding and sealing.

Features

Polyurethane sealant has high elongation and good flexibility.
It has high elasticity, strong adhesion, good sealing and waterproofing effect, high wear resistance, high and low temperature resistance, ready-to-use for open cover, easy to repair, tear resistant, and no cracking.

Product usage

Polyurethane sealant is used for joint sealing with telescopic joints such as high-grade roads, bridges, aircraft runways, and connections at pipe joints such as sewers, underground gas pipelines, wires and circuits of concrete, ceramics, and PVC materials. Sealing, sealing at the connections of subway tunnels and other underground tunnels, etc.

Packaging specifications: 25kg/barrel Color: gray, black.

Construction method

1. The surface of the substrate is clean, strong, and free of loose matter. It must be dry. It is prohibited to construct on the surface of the damp substrate and the surface must be clean.
2. Put the sealant into the seam filling equipment, and put the hose out deep into the bottom of the construction joint and inject the seam filling glue into the construction joint.
3. Leave blank: Because the construction joints will expand and contract with temperature changes, the surface of the joint filling glue should be about 2mm lower than the road surface after construction.

Notes: Sealed and stored in a low-temperature and dry place.
