Microshield™ Masking Aid

Application hints for the use of Microshield Masking Aid for the preparation of samples for TEM



Chinese




Microshield can be used in a number of different ways using different protocols. We are not sure that one is necessarily better than others, it might be more a matter of personal style and preference than whether one method is better than another.

In short, all one has to do is to "mask" that area of the sample that should not be etched, with a thin, uniform coating of Microshield.

Usually, one would want to mount their sample first, and then mask (e.g. with Microshield) the underside (when using a single jet system). It is important to not coat over the area of the sample that will make electrical contact with the jet polisher as the lacquer behaves somewhat as an insulator.

At the completion of the thinning step, the Microshield can be removed with the Microshield Remover.
