Water-ShieldTM
Hydrophobic Protection from Puretone
The Water-ShieldTM bio-compatible
coating is a highly durable “Teon-like”
amorphous carbon polymer coating that
protects small items like personal electronics and other
articles 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. The
coating is applied in house after production.
Water-ShieldTM is created by the plasma decomposition
of a vapor containing “Teon-like” material, the resulting
lm is a cross-linked polymer which creates a hydrophobic
“Nook and Cranny” seal, i.e. it prevents uids 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 200,000ft
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 nanometer lm thickness, only
about 1/2000th the thickness of an average human hair, and
is normally completely invisible to the naked eye.
