Abstract
The adhesion between a low surface energy (i.e., nonpolar) material, e.g., a polyolefin such as polyethylene, and a high surface energy (i.e., polar) material, e.g., a polyester, polyurethane, polycarbonate or polylactic acid, is promoted by blending with the nonpolar material typically from 15 to less than 50 wt % of a diol-based thermoplastic polyurethane (d-TPU), e.g., a polydiene diol-based TPU, based on the combined weight of the nonpolar material and the d-TPU. The promoted adhesion allows for the effective painting, printing, over-molding or HF-welding of a nonpolar substrate, e.g., a polyolefin film, with a polar coating, e.g., a paint, ink, etc. Aqueous dispersions can also be made from the blend of nonpolar material and d-TPU.
