使用方法 

1、准备工作：使用干绵布将接着面的灰尘、油污、等除去，再以三氯乙烯、甲乙酮、甲醇等溶剂或者用0111系列无毒环保无腐蚀性专用清洗剂擦拭，清洁粘合表面。胶水若长期存放，用前应摇匀。

2、打磨：被粘物表面可适当进行打磨，表面粗糙度以0.75～2μm为宜。若大于3.5μm，会使间隙过大而降低粘接强度。

 3、上胶：可采用刷涂或刮涂之方式直接将厌氧胶涂在被粘物表面上。被粘物的两个表面均涂胶效果最好，但在其中一个表面涂满胶再装配效果也不错。对于螺栓，只需将胶涂在螺栓端和螺纹口即可，旋紧时胶液会充满整个间隙。若是裂纹或不方便拆卸的部位，可采用渗胶（低黏度胶）的方法。涂胶量以填满间隙为宜，最佳的胶层厚度为0.03～0.075mm，厚度过大会使强度降低。

4、装配：装配时应来回转动零件，以使胶液铺展开，让零件尽快定位。装配的零件一般在室温下便可部分固化。一般情况下，粘接面积越大，间隙越小，固化越快。固化3小时后粘接强度可达额定值的50%-65%，24小时即可达到最大值。随着温度的升高，固化时间缩短，粘接强度增高。

5、密封保存：厌氧胶暴露在空气中不会固化，可等被粘物完全固化后，再用干布或蘸丙酮擦拭清除残胶。请勿将已倒出的胶液再倒回原瓶，以免污染胶液。胶水24小时后达到最佳强度，用完请将胶水放到阴凉干燥处保管。

温馨提示 

1、 厌氧胶适合于金属之间的粘接，不适合用塑料、木、纸等多孔性材料。对于钢铁、铜及其合金等活性金属表面粘接固化快、强度高。对于不锈钢、锌、镉等金属表面固化慢、强度低。

2、 用于大间隙的粘接和密封，中间需加金属垫片或使用专用厌氧胶。低温时使用或者在惰性金属表面使用厌氧胶需在被粘物表面上涂促进剂，温度太低时，可将零件预热。

3、粘接操作环境尽量保持干燥，相对湿度小于60%。粘接件应避免在碱性介质中使用。

4、若需拆卸时，可将粘接件加热到260摄氏度~316摄氏度，趁热拆卸。如果高温不允许，可使用有机溶剂如二氯甲烷等混合溶剂或者特种清除剂。

5、厌氧胶不能装入金属容器，其他容器也不能装满。

6、皮肤接触时立即用肥皂水清洗，假如眼睛不小心接触到时，马上用大量清水冲洗，严重者请及时就医。

7、0111系列胶水具少许刺激性，请在大量使用时工作场所应保持通风且防止烟火。

8、当有大量泄漏时先打开窗户通风，并且注意防火安全。
