摘要:
The present invention relates to inner coatings of metal food containers and packaging and to a process for their production. The coatings are appied to the inside of at least a portion of the surface area of containers that are in direct contact with foods or other consumable products and subsequently cured. The coatings include a) at least one polyisocyanate containing an average of at least two NCO groups per molecule, at least 95% of the NCO groups being blocked with a blocking agent, and b) at least one polyhydroxyl compound containing an average of at least two hydroxyl groups per molecule that react with NCO groups.
