Precautions
1、Clean and dry the surface to be adhered to.
2、Squeeze the glue onto the cleaned and clean surface to make it evenly distributed, and then close and fix the surface to be adhered.
3、The thickness of the potting should not exceed 5mm as far as possible. The deeper the adhesive layer is, the longer the curing time is.
4、The speed of curing is related to temperature and humidity. High temperature and high humidity can promote moisture curing. It takes 7 days to fully cure.
5、It is recommended to store in a dry and cool place below 30°C.
