The Universal Selection Source: Adhesives Ingredients

Polyurethane Adhesive
Polyurethane Adhesives are known for toughness and flexibility even at low temperatures. They have fairly good shear strength and excellent water and humidity resistance. One-component polyurethane adhesives consist of isocyanate-containing prepolymers dissolved in a solvent carrier while two-component polyurethanes consist of a polyol component (resin) and an isocyanate component (hardener). Polyurethane adhesives form strong bonds to rubber, plastics, metal, wood, paper, ceramic, and fabrics. Two-component polyurethanes are used for large-surface adhesive bonds, like in in vehicle superstructures.
