Our customer wanted to mitigate device product losses and reduce the returns due to corrosion from sweat and loss of receiver sensitivity due to gooey ear wax plugging their sound tubes.


An oleophobic nano-coating which reduces moisture, sweat corrosion and cerium from passing through ear wax traps as well as a nano-coating over the entire device. Our “Repellix” coating solution is the best coating on the market with higher hydrophobic contact angles than the competitor’s plasma-based CVD films. The Repellix water contact angle was >160° even on smooth surfaces while the competition was only 110°.


Our customer was able to see a decrease in returns and provide a better-quality product than their competition.

Let’s engineer something better, together.
