Is Pot and Shelf Life critical on conformal coatings?
It depends on the conformal coating material type as to how important shelf and pot life need to be monitored. The most critical type of conformal coating which is affected by pot life is moisture cure materials such as conformal coating silicones. Any premature curing of the moisture cure product can cause production problems and the silicone coatings must be monitored carefully. Other conformal coatings that may have pot life issues are two part products, which when mixed, will begin to cure within the allotted time period and cannot be reversed. The manufacturer’s recommended shelf life and pot life should be reviewed and tracked closely.
