摘要

Coating of cans, free of badge and BPA, the present invention relates to a composition, which is useful for producing coatings for substrates of metal plates, metal cans, to contain and / or carry food or beverages, or its lid, and comprising the following with Components: (a) 30 to 90% by weight of a polymer of polyvinyl chloride (PVC),(b) 7 to 25% by weight of an acrylic resin, (c) 3 to 40% by weight of an agent, crosslinking agent, which is produced from phenol, P - t - butilfenol, xylenol, or a mixture of them, and formaldehyde, (d) to 8% by weight of additive. (E) to 50% by weight of pig growth, and (f) a component solvent.Where all percentages by weight are based on the total dry weight of the composition of the coating (without solvents) and the composition is substantially free of bisphenol-A - diglicidil ether (badge) and also substantially free of resins of bisphenol - a.The composition produces coatings of metal cans, which have appropriate flexibility, scratch resistance, adhesion and resistance to sterilization, when processed in contact with food. The coatings are suitable for cans in three parts, as well as the stretched metal cans with depth.Particularly, they are, however, useful for lids that are going to be opened under splitting, due to their extraordinary flexibility and resistance to sterilization.
