Paint Film Finishing - a Paint Replacement Option 953386

The drive for environmentally compliant coatings is the political result of society's desire for a clean atmosphere. All phases of the Coatings Industry have been affected by the regulations imposed to achieve the desired goal.Automotive finishing, in particular, has undergone a series of revolutionary changes in recent years. In the seventies and early eighties, automotive finishing was relatively simple. The finish designer had two primary chemistry options, mono-coat acrylic lacquer or mono-coat acrylic enamel. The two systems were available in a range of colors including aluminum pigmented metallics. Substrate was not an issue, it was steel.Today the finish designer must know the substrate to be finished (steel, aluminum, or a growing list of plastics, each requiring its own unique finish or primer) in order to select a compatible finish system. Then the designer must choose between a host of finish options - high solid enamels, aqueous and non-aqueous dispersions, powder coats, and one and two part urethane to name a few. Now add Paint Film to the list.Paint film, as the name implies, is a paint converted to dry film form prior to application. It is typically delivered to the customer as a solvent free roll of material to be incorporated in the part production process.Film finishes are applied to metal and plastic for automotive and non- automotive markets
