Product Introduction


The one-component polyurethane sealant is mainly composed of polyurethane prepolymer, fillers, and other additives. It is a solvent-free one-component sealant that cures at room temperature. It is in a paste state and can be extruded or applied during construction. It cures by reacting with the trace water vapor in the air and bonds by reacting with the active groups on the surface of the substrate. The color is generally black, and there are also white, gray, etc.


Applications

  • Construction Field: It is used for the filling and sealing of doors, windows, glass, etc.; the connection of building materials such as precast concrete components and the filling and sealing of construction joints; the bonding and caulking of lightweight structures (such as curtain walls) on buildings; the waterproof caulking of facilities such as balconies, swimming pools, and bathrooms; the sealing of insulating double-glazed windows and insulating window frames, etc.
  • Civil Engineering Field: It can be used for the caulking and sealing of highways, bridges, airport runways, etc.; the connection and sealing of pipeline joints such as sewers made of concrete, ceramic, PVC, and other materials, underground gas pipelines, and electrical circuit pipelines; the sealing of the joints of subway tunnels and other underground tunnels, etc.

Features

  • Diverse Performance: The performance can be adjusted within a wide range, and it has strong adaptability.
  • Good Mechanical Properties: High tensile strength, large mechanical strength, and good wear resistance.
  • Strong Adhesion: It has good adhesion to various materials such as metals, rubbers, woods, cement components, ceramics, and glasses.
  • Excellent Elasticity: Good elasticity and excellent resilience, and it can be used for dynamic joints
  • Good Weather Resistance: Good weather resistance, and the service life can be as long as 15-20 years.
  • Good Chemical Resistance: Good oil resistance and resistance to biological aging.
  • Convenient Construction: One-component design, no need for on-site mixing and blending, reducing operation steps and errors.

Product Packaging Specifications

  • Common Specifications: Usually, it is packaged in soft tubes or bags of 600mL per piece, and generally, 20 pieces are packed in each carton.
