SHELF LIFE保存方法
Store at 21 - 30 ºC in a dry place. Hardener-6020 is moisture sensitive, after each partial use, purge with dry nitrogen and tightly reseal. Before use, mix and stir all components at warm in case of filler settling.保存于21- 30 ºC的干燥地方。Hardener-6020 容易受潮，每次用完后應(yīng)用干氮?dú)馇謇砀蓛舨⒚芊獗４妗Ｔ谑褂们?，在溫暖環(huán)境下攪拌混合各澆注組分以防止填充料下沉。
