Usage
Preparation
Clean the un-bonded or uncoated surfaces by removing the rust, ash, and oil, etc.
Application
Pierce the opening with the tip of the cap. Fix the nozzle, and coat the clean surface evenly with the adhesives, then bond the two surfaces.
Curing Condition
The curing progress is from outer surface into inner surface. The elastomer can get cure in the depth of 2~4mm in 24 hours (at room temperature, 55% moisture), if the position of the bonded parts is too deep or the temperature is too low, the full curing time will be extend.
Advise user preparing enough time to let elastomer get full cure in order to stable its properties for the next progress.
Attention
1. After the application, screw its nozzle tightly and store in dry and cool place for next time using.
2. Some cured adhesives around the opening when you use it again, just remove the cured, and use the uncured.
