Abstract
Two-component polyurethane adhesives include a polyol component and a polyisocyanate component. The polyol component includes a polyether polyol and specific amount of an aliphatic diol chain extender. The polyisocyanate component includes an isocyanate prepolymer made by reacting an aromatic polyisocyanate with a polyether. The adhesive has an excellent combination of a prolonged open time followed by curing to form a strong adhesive bond. The adhesive is especially useful for bonding carbon fiber-reinforced plastics.
