制备醚化蜜胺甲醛树脂的液体组合物的方法
摘要：
本发明涉及一种制备具有低甲醛含量的醚化蜜胺甲醛树脂，即被伯C1-C6链烷醇醚化的蜜胺甲醛树脂的液体组合物的方法。本发明还涉及游离甲醛含量小于0.3重量％的醚化蜜胺甲醛树脂的该类液体组合物。醚化蜜胺甲醛树脂的液体组合物可以在涂料组合物中用作交联剂。
摘要（英）：

The present invention relates to a process for preparing liquid compositions of etherified melamine formaldehyde resin, namely melamine formaldehyde resin etherifiedwith a primary C1-C6-alkanol, whichhave low formaldehyde contents. The invention also relates to such liquid compositions of etherified melamine formaldehyde resin having a content of free formaldehyde of less than 0.3% by weight. Theliquid compositions of etherified melamine formaldehyde resin are useful as crosslinking agents in coating compositions.
