建议添加量 0.1-1%, 使用过程需要高速搅拌30分钟。添加量: 一般为整个体系的千分之一至三, 对于填料添加比较大的涂料体 系, 可以适当多添加。 It is recommended to add 0.1-1%, and the use process needs to be stirred at high speed for 30 minutes.Add amount: generally one-thousandth to three of the entire system, for the filler add relatively large coating system, can be appropriate to add more. |
作用Function |
Surfynol 440 主要作用是润湿/降低表面张力(包括动态静态张力 ), 对于表面缺陷要求比较严格涂膜, 可以防止缩孔、针眼、鱼眼 。Surfynol 440 用在复膜胶, 润版液, 水性油墨/涂料内使用, 起到润湿降低表面张力的作用。 SURFYNOL 440 具有 的亲水 性、润湿、消泡等性能, 明显地降低水基体系表面张力性能, 特 别是降低动态表面张力。 The main function of Surfynol 440 is to moisten/reduce surface tension (including dynamic and static tension), and the coating film is strict for surface defects, which can prevent shrinkage, pinhole and fish eye. Surfynol 440 is used in coating adhesives, moistening fluids, and water- based inks/coatings to moisten and reduce surface tension. SURFYNOL 440 has the properties of hydrophilic ity, wetting and defoaming, which can significantly reduce the surface tension of water-based system, especially the dynamic surface tension. |
