Initial comparison of rapid test methods for coating coverage & Evaluation of the benefits in combining conformal and hydrophobic coatings
Presented by Laura Kent

Evaluations of the effectiveness of coatings can currently take upwards of a 1000 hours using standard surface insulation resistance (SIR) measurements. With the NPL developed condensation test, initial screening and in-process quality control is available within 48 hours. Even shorter testing time periods may be possible with immersion testing and allow for the exploration of contamination tests, for example sea water and engine coolants.
Whilst traditional conformal coatings have been highly successful, they still absorb some moisture due to their polymeric nature. Issues have also arisen in terms of the coverage of fine details. The application of a hydrophobic coating, on its own or in addition to the conformal coatings may prove a potential solution to overcome these issues. This web in also looks at the application of these hydrophobic coatings using the NPL developed draft test standard, the combination of these and effects of ageing.
