Blushing

 

Typical failure mechanisms in conformal coating processing: Blushing

This video is about one of the typical failure mechanisms in conformal coating processing called  Blushing.

Some of the problems from blushing can include surface tackiness or greasiness, incomplete cure, poor adhesion, poor adhesion on over-coating, coating discoloration over time and poor gloss retention (matte finish).

The video will help you know how to prevent blushing in the conformal coating process.
