Processing Information

Processing:

• Mix A and B component according to the right weight ratio or volume ratio. The mixing speed should be moderate to avoid bubble. The potting should be finished within pot life.

Note:

• Small bubble may be found when the air is entrapped during mixing and could not be released after potting and curing.
• Big bubble may be found if B component reacts with water curing storage. Thus the sealing of the pail is quite important after usage.
