COATING COMPOSITION FOR FOOD CONTAINERS

摘要

The invention relates to a coating composition for food containers, which comprises: a) 20-40 % by weight of a binder polymer from the group "water-soluble or water-dispersible polyester resin; water-soluble or water-dispersible acrylic polymer"; b) 5-20 % by weight of a cross-linking urethane resin which is virtually free from free NCO groups; c) 20-70 % by weight of water; d) 0-18 % by weight of an organic solvent; and e) 0-5 % by weight of customary auxiliaries. Here, the binder polymer has an OH number of at least 10 mg of KOH/g and the urethane resin has a content of NCO groups (blocked) of at least 5 %.
