Abstract
Provided are adhesives containing a phenoxy resin grafted with methyl methacrylate (MMA) and/or methacrylic acid (MAA), and including a uretdione or a silane. The adhesive compositions are completely or substantially absent free isocyanate. The grafted phenoxy resin forms crosslinking which allows the adhesive to chemisorb to a metal surface, diffuse and entangle in a urethane elastomer and/or provide crossbridging and/or crosslinking across an interface of the adhesive and a cast urethane. Methods of adhering a castable urethane to a substrate, using the provided adhesives, are also provided.
