无溶剂复合粘合剂与水性油墨的匹配性

The Matching between Solvent-free Composite Adhesive and Water-based Ink

水性油墨印刷后或多或少会残留一些水，而无溶剂聚氨酯粘合剂中异氰酸酯基团可与水反应，这就会对复合产生一定的影响，比如外观、剥离强度等。本文详细介绍了如何通过选择合适的配方和体系，令无溶剂复合和水墨印刷达到良好的匹配性。

More or less some water will remain after printing of water-based ink,while isocyanate groups in solvent-free polyurethane binder can react with water, which will have a certain impact on the compound,such as appearance and peel strength and so on. This article describes explicitly how to select suitable formulation and system to make solvent free compound and Water-based ink printing achieve good matching.
