NEW for 2015: CENS Water-Shield

CENS Hydrophobic Protection

As part of the continual CENS product development and improvement program; we have installed new state-of-the-art equipment at the Rochester factory, applying a hydrophobic nanocoating to CENSdevices, called Water-ShieldTM.

ALL CENS Hearing Protection devices are now protected with Water-ShieldTM as STANDARD at no extra cost.

The Water-ShieldTM bio-compatible coating is a highly durable “Teflon-like” amorphous carbon polymer coating that protects CENS devices from accidental liquid exposure.

Tests have shown that a hydrophobic coating can reduce water ingress by 3x to 5x over an unprotected product when exposed to simulated rain-chamber conditions.

Water-ShieldTM is created by the plasma decomposition of a vapour containing “Teflon-like” material. The resulting film is a cross-linked polymer which creates a hydrophobic “Nook and Cranny” seal, i.e. it prevents fluids from entering the small openings in portable electronics cases. It also permeates into the interior through any opening.

The Water-ShieldTM process is created at reduced pressures of deep outer-space, at an equivalent altitude of 200,000 ft above sea level, so that the carbon atoms can diffuse deep into the product, resulting in a hydrophobic coating over every exposed surface.

Water-ShieldTM is applied at nanometre film thickness, only about 1/2000th the thickness of an average human hair, and is completely invisible to the naked eye.

Additional Benefits:

  • Greater protection from water
  • Improves reliability
  • More hygienic
  • Increases device life
