Directions:
1. Measurement
Fully mix component A before using, accurately weighing A part, and then put the Part B to mix with Par A by mix ratio. It can adjust by your own needs according to the specification.
2. Mixing
Put Part B in the bottle with Part A, evenly mix them immediately. And should tighten-sealed the Part B after using.
3. Pouring
Put the mixed glue evenly into the product which need encapsulate immediately.
4. Curing
The encapsulated components can be room cured, and it can put into next process after 10 to 24 hours full cure.
