A method of manufacturing an insulating film-forming material comprising a curable composition comprisING (A) an inorganic polymer compound or an organic polymer compound and (B) an organic solvent, which comprises treating the curable composition with a zeta potential-producing filter material. Because the curable composition has a very small content of alkali metals and heavy metals, the composition is suitably used for the manufacture of materials for forming insulating films which have a wide variety of applications in the electronic field.
一种制造绝缘成膜材料的方法,该材料包含一种可固化组合物,其中(A)无机高分子化合物或有机高分子化合物和(B)有机溶剂,该方法包括用产生 zeta 电位的过滤材料处理该可固化组合物。由于可固化组合物中碱
金属和重
金属的含量极少,因此该组合物可用于制造形成绝缘膜的材料,这些材料在电子领域有着广泛的应用。
