hyco Finishing Technologies, LLC, in anticipation of changing
customer requirements, has spent a number of years
researching hexavalent chrome free technologies. The
result is a series of viable, production proven hexavalent
chrome free coatings designed to meet varied industry
corrosion requirements and product mix.
ecause Whyco's business is metal finishing (as
it has been for over 55 years), we know that it is necessary to
reduce a technology to a practice - to make a system
that will work under daily production conditions, not
just in the lab.

Whyco's technical staff will work with you to
provide the best Hex Free Technology for your application.
Whyco's Hexavalent Chrome Free Coatings
provide extreme corrosion protection even after the most
severe crimp.

- Current colors range from blue/clear and yellow
chromates to a matte black organic paint.
- Barrel and Rack plating capabilities
- High volume production
