Method of use:
1, measurement: weighing A, B, m.p., proportional distribution glue.
2, mixing: first A component mix, then B component to join with A component with the glue containers mixing.
3, pouring: mix will melt TuoPao (vacuum or quiet place), can be carried out after potting.
4, curing: potting good parts at room temperature under curing, solid can enter early next working procedure, to fully cure to 24 hours. Summer temperature, curing is quicker, The winter of low temperature, curing will slowly.
Note: in curing produces in the process of small molecules incomplete release before, do not hold potting device fully closed, and high temperature (> 100 ℃). If need to fully closed, in guangdong area, suggest summer 3 days, winter 7 days before to undertake airtight.
