35 总结 The most important criteria for good wetting is the surface tension of a coating vs. surface energy of a substrate 良好的润湿性主要取决于涂层的表面张力与基材的表面能间的相合性 The surface tension of the coating has to be lower than the surface energy of the substrate 涂层的表面张力必须低于基材的表面能 Polar/ Disperse split has to fit 两者间其极性和分散部分需相适宜 In water based coatings wetting agents are necessary to adjust the surface tension of the liquid phase 水性涂料中需有润湿剂来调整液相的表面张力 Under dynamic conditions the influence of surface active on surface tension might be significantly different compared to the equilibrium state value 在动态条件下, 表面活性剂对表面张力的影响可能与静态下的明显不同 BU Paper and Coatings Additives / Defoamer/bi
