Usage:
1) Before use, the materials should be cleaned to ensure they are dry and free of contaminants.  
2) A and B components are mixed in a 1:1 weight ratio, and it is recommended to vacuum defoam before applying to the target component.
3) High temperature curing can improve production rate and adhesion between substrates.  

Notes:
1) Please use up the mixed adhesive material at once to avoid waste.  
2) When the adhesive comes into contact with a certain amount of organic compounds such as N, P, S, as well as ionic compounds of elements such as Sn, Pb, Hg, As, it can cause poor hardening. Therefore, do not mix these substances into it.  
3) Before use, please keep the product sealed and store it in a dark place.
