Abstract

Patente de Invenção: <B>"COMPOSIçãO DE REVESTIMENTO PARA RECIPIENTES DE ALIMENTO"<D>. A invenção refere-se a uma composição de revestimento para recipientes de alimento, que compreende: a) 20-40% em peso de um polímero ligante do grupo de "resina poliéster dispersável em água ou solúvel em água", polímero acrílico dispersável em água ou solúvel em água"; b) 5 à 20% em peso de uma resina de uretano reticulada, que é virtualmente isenta de grupols NCO; c) 20-70% em peso de água; d) 0-18% em peso de um solvente orgânico e e) 0-5% em peso de auxiliares comuns. Aqui o polímero ligante possui um número OH de pelo menos 10 mg de KOH/g e a resina de uretano possui um teor de grupos NCO (bloqueados) de pelo menos 5%.Invention Patent: <B> "COMPOSITION OF COATING FOR FOOD CONTAINERS" <D>. The invention relates to a coating composition for food containers, comprising: a) 20-40% by weight of a binder polymer from the group of "water-dispersible or water-soluble polyester resin", water-dispersible acrylic polymer or soluble in water "; b) 5 to 20% by weight of a cross-linked urethane resin, which is virtually free of NCO groups; c) 20-70% by weight of water; d) 0-18% by weight of a organic solvent ee) 0-5% by weight of common auxiliaries Here the binder polymer has an OH number of at least 10 mg KOH / g and urethane resin has a content of NCO (blocked) groups of at least 5%.
