Development of environment-friendly coating materials for steel and zinc galvanized surfaces for use in exterior applications

The coating material developed, “Ökopol”, is based upon a ricin oil/demara resin bonding agent, a natural resin, bentonite and dearomatised benzene. Positive results have been obtained in both laboratory trials and short-time tests. Under operational conditions, this material has proved inferior to conventional solvent-based coatings, in terms of durability.
