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°.

Result / 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.
