水乳型聚氨酯环氧硅氧烷常温交联 交联体系在皮革涂饰中的应用(Ⅱ)

Epoxy Siloxane as Ambient Temperature Cross-linking Agent for aq. Polyurethane Its Application in Leather Finishing (Ⅱ)

报导了水乳型聚氨酯与环氧硅氧烷常温交联体系在皮革涂饰中的应用。研究发现环氧硅氧烷常温交联 体系也可大幅度提高皮革涂层的耐水、耐有机溶剂及粘接牲能，对耐涂层的耐曲绕性能，几乎不产生负 面影响。

The application of aq. polyurethane cross linked by epoxy siloxane for leather coating properties, such as dry and wet rub-fastness, solvent resistance, adhesion were dramatically improved by this ambient cross linking system. And the property of flex resistance were little affected.
