1.Measuring & mixing
Before you begin, accurately weigh Part A and Part B. Put Parts A and B into mixing container, mix thoroughly couple of minutes to make sure that you scrape the sides and bottom of the mixing container several times. After mixing parts A and B, vacuum degassing is recommended to eliminate any entrapped air in mixture. Vacuum time should be around 5~8 minutes.
2.De-airing
Can use natural deaerating and vacuum method.
Natural deaerating: let the mixed glue rest for 20- 30 minutes;
The vacuum deaerating: take 5-10 minutes at vacuum degree 0.09- 0.1 MPa.
3.Pouring performance
Pouring-Before potting, the surface of parts and the mixing container keep clean and dry.)
Encapsulate the mixture into the products to finish the pouring operation.
4.Curing / Post Curing
Vulcanizing:Put the sealed product in room temperature and let it cure in natural condition. It needs 6-8hrs for complete curing in room temperature. If you need to speed up, you can accelerate the curing process in higher temperature. Generally, it would take 60mins to cure completely under 60ºC; 30mins under 80ºC and 20mins at 120ºC.
