| Résumé : |
This product comes under Metal Decorating for a Can coating, applied by roller to thin sheets. Many problems were involved in developing this formulation. Popularly known as OP WARNISH, this is used as a top-coat. Usually four colour printing is done on tin sheets and every coat has to pass through oven. Naturally, the gloss of the earlier coats will be diminished, therefore it does a great job in maintaining the glossiness. It also requires Marproof properties, which can be achieved with the use of PA 52, to satisfy finger nail testers. And to make it scratchproof while handling. |
