                造成漆膜发白的主要原因

                发布时间:2020-08-20 点击量:0

                1)底材含水率高或施工环境湿度大,涂料喷好后,水分会慢慢地向外渗透。当到达面漆层时,由于面漆致密性好,水分无法继续往外蒸发,水与漆膜不相溶,且水与漆膜的折光率不一样,故而导致」发白的现象,面漆喷得越厚发白越明显,时间越长发白〓越明显。

                2)固化剂∞与树脂相溶性差,也是造成漆膜发白的原因之一,部分厂家为节约成本降低固※含量,且为了保证⌒漆膜的干燥性,三聚㊣ 体用量过大(特别ω 是相容性不好的三聚体),采用后三聚体加成物也会带来发白的问题。
