Not sure if this is the right subforum, but as a mechanical guy I was hoping someone could point me in the right direction.

When using a temperature cured two part silicone potting or 1 part conformal coating what methods can be used to verify/validate a cured state?

I've tried technical data sheets and manufacturers but they tend to stick to the "We recommend all customers test to their own specifications" mantra.

Most documents say it is considered cured when it reaches 90% of its optimum properties...but those properties tend towards tensile strength, dielectric strength, hardness...all which seem hard to measure and make me nervous.

Thanks for any guidance.
