Friend who bought a special car for the first time must not understand what the black, yellow and blue colors of the license plate mean. I recently asked a friend who understands a special car and learned that: PUR (Polyurethane Reactive, Chinese full name is moisture curing reactive polyurethane hot melt Adhesive. The main component is isocyanate-terminated polyurethane prepolymer. The adhesion and toughness of PUR (elasticity can be adjusted, and it has excellent adhesion strength, temperature resistance, chemical resistance and aging resistance) In recent years, it has become the adhesive industry It is one of the important varieties of it. Now it is widely used in packaging, wood processing, automobile, textile, electromechanical, aerospace and other national economic fields.
After the two adherends are laminated and cooled, the adhesive layer condenses to play a bonding role; then, with the help of the moisture existing in the air and the moisture attached to the surface of the adherend, it reacts with and extends the chain to form a polymer with high cohesion. material, so that the adhesion, heat resistance, low temperature resistance, etc. are significantly improved. Due to its extremely high reactivity, it shows excellent adhesion to a variety of materials, and is widely used in the top cover of washing machines, the top cover of disinfection cabinets, book binding, car lights, furniture edge sealing, shoemaking etc. bonding.
