Abstract
Two-component polyurethane adhesives include a polyol component and a polyisocyanate component. The polyol component includes a polyether polyol and an aliphatic diol chain extender. The polyisocyanate component includes an isocyanate prepolymer made by reacting an aromatic polyisocyanate with a poly(butylene oxide) polyol. When cured, the adhesive is highly resistant to heat and humidity, and exhibits an unexpectedly high modulus and tensile strength.
