HOW TO USE

 

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

a.The curing progress is from outer surface into inner surface.

b. The elastomer get cure with the depth of 2~4mm in 24 hours (at room temperature, 55% moisture). if the bonded parts is too deep (especially the parts not easy to contact with air) 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 keep the properties stably. 

 

 

 

ATTENTION

1. After the application, screw its nozzle tightly and store in dry and cool place for next time using.

2. There may be some cured gel around the opening when you use it again, just remove the cured, and use the uncured.
