Abstract
Articles including durable and icephobic and/or biocidal polymeric coatings are disclosed. The polymeric coatings can include a bonding layer which may contain a substantially fully cured polymeric resin providing excellent adhesion to metallic or polymer substrates. The polymeric coating further includes an outer surface layer which is smooth, hydrophobic, biocidal and icephobic and, in addition to a substantially fully cured resin, contains silicone comprising additives near the exposed outer surface. The anisotropic polymeric coatings are particularly suited for strong and lightweight parts required in aerospace, automotive and sporting goods to applications. A process for making the articles is disclosed as well.
