Polyethylene/polyurethane blends for improved paint adhesion

• Adhesion of polyolefin to paint is significantly improved by blending polyurethane. • Outermost surface of injection molded blends is determined to have more TPU. • Composition of blends at 5 μm below surface is determined to be the same as bulk. • SEM and AFM gave evidence on inter-diffusion betw...
