Direction for using:

Cleaning: Clean the surface of thread, remove greasy dirt etc and dry, suggest to use 7755 cleaning agent to improve the cleaning efficient

Dispensing: Shake up before using, dispensing the adhesive on the thread, sufficient to fill all the gap between thread, and fix in the proper position on the code requirement.

Curing: The best sealing performance if the gap small, will affect the curing speed if the gap big, suggest to use 7769 accelerant for big gap case, to improve the sealing effect. In order to achieve the best performance, suggest the curing time more than 24 hours.

 

Storage:

18 months during 8-28 and keep away from sunshine and damp.
