Novel coil coating systems using fatty acid based reactive diluents

Limitation of volatile organic compound (VOC) emissions has lead to the development of new coil coating systems with reduced solvent content. Reactive diluents derived from vegetable oils have been used to substitute up to 40% of the white spirit. The use of vegetable oil derivatives further reduces the handling of solvents improving the workplace environment and safety, enhances the film properties, and introduces a renewable resource in the final coating. The concept can be described as a melamine crosslinkable alkyd which is formed in parallel to the crosslinking process. (C) 2010 Elsevier B.V. All rights reserved.
