The Science Of Precision Coatings


A licensee of the Armoloy Corporation, Armoloy of Illinois has been in operation in its original location since 1969 and is located 60 miles west of Chicago, in DeKalb, Illinois.

Providing a full range of surface coatings, from Thin Dense Chrome to Nickel-Teflon, Armoloy of Illinois serves the greater manufacturing community in the United States, as well as customers in a dozen other countries.

With a fully staffed chemistry lab, Armoloy of Illinois functions as an innovation incubation center for Armoloy Corporate. It’s often the first place customers in the nuclear power, aviation, food-manufacturing and other sectors turn to for solutions to “impossible” coatings challenges.

In 2019, it became a model for environmental sustainability as Armoloy’s first 100% closed-loop coatings facility, featuring the most advanced air-filtration systems and a zero-discharge wastewater program.

Armoloy of Illinois coatings address the three major issues common to machined components:

  1. Excessive or premature wear
  2. Friction
  3. Corrosion

With 200 years of plating experience among its technical, sales and managerial staff, Armoloy of Illinois can engineer a surface-coating solution for nearly every component application.

Armoloy of Illinois is ISO 9001:2015 certified.
