A new coating for deep drawing with preservation-lubricant-primer properties
article
During the production process of manufacturing metal products from steel sheet, large amounts of corrosion preventives and lubricants are being used. The corrosion preventives provide corrosion protection of the metal until the final coating is applied on the metal product. The lubricants are being used during the cold metal forming in order to prevent damaging of the metal product and forming tools. From an economical and environmental point of view, the use of these agents is unfavourable because it involves time-consuming washing steps and chemical waste. At TNO products were developed which can perform both a preservation and lubrication function, and furthermore are compatible with commercial paints that are generally used for coating of metal products. Thus, no washing steps are required. The products are based on epoxidized oil, and can either be thermally or UV cured. The products show anti-corrosion and lubrication properties, which are comparable or better than the present properties of commercially available preservation oils and lubricants. Next to this, commercial coatings which are applied on cured layers of these products show good adhesion and film forming properties.
