Pressure-sensitive adhesive composition is disclosed wherein the adhesive is a 100 % solids, no solvent, tacky oil that can cure at ambient conditions. The adhesive comprises an acrylic oligomer component and a polyurethane prepolymer in combination. The oligomer comprises repeat units, corresponding to acrylic acid, lower alkyl acrylate and hydroxylated lower alkyl acrylate monomers. The prepolymer is formed via polyisocyanate reaction with a multifunctional active hydrogen containing compound, such as a polyol. |
