ABSTRACT:
Articles of manufacture are provided with a low surface energy, permanently non-stick, non-fouling and ice-phobic surface by a system of coating comprising applying a primary coating having a surface energy of 22-28 dynes/cm.sup.2 comprising a novel polymeric material having non-stick and hardness properties and then applying a top coating having lower surface energy of from about 18-21 dynes/cm.sup.2 comprising a siliconic polymer and interdigitating means to make the top coating permanent, the means preferably comprising a bi- or polyfunctional organic compound adapted to wet the surface of the primary coating and chemically or physically bond thereto and to couple to the siliconic polymeric substance in the top coating. The coated substrates are resistant to marking by graffiti, to adherence by marine fouling organisms, and frozen ice on the surface is easily removed.
