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，每次用完后应用干氮气清理干净并密封保存。在使用前，在温暖环境下搅拌混合各浇注组分以防止填充料下沉。
