PU / Polyurethane Adhesive

Polyurethane Adhesive (PU adhesive) is a glue with polyurethane rubber and polyurethane prepolymer as the main components.

This type of  adhesive has high tensile strength, excellent elasticity, abrasion resistance, oil resistance, and cold resistance, but it has poor water resistance, especially alkali resistance. It can be divided into heating vulcanization type, room temperature vulcanization type, and hot-melt type. Among them, the room temperature vulcanization type is divided into one-component and two-component.

 

It is widely used as a caulking bonding  and sealing material in buildings, squares, and highways, as well as  bonding and sealing in automobile manufacturing, glass installation, electronic filling, submarines, and rockets.

For Maxtech, we mainly do these three parts as follows:

  • Auto glass Adhesive
  • Construction Adhesive
