Reducing and eliminating costly combi mixer repairs with food grade ARC Industrial Coatings


Chesterton and ARC Coatings

Severe abrasion of the interior of the combi mixer required annual removal of the mixer to a maintenance shop where welding repairs were performed.

The strong abrasion of the residues from corn milling residues used in animal feed processing caused a strong abrasion inside the mixer.

The customer relied on the hands of Chesterton specialists to reduce or eliminate the requirements to repair the welding mixer and perform any future on-site repairs using an FDA compliant wear-resistant coating.

Chesterton products:

  • ARC MX FG – Abrasion Resistant Coating for Fine Particle Wear
  • ARC S1PW – Brush-Roll-Spray Applied Moderate Chemical Resistant Coating


Signs of abrasive wear to the internals of mixer

ARC S1PW – NSF 61 Certified




Decontaminate and abrasive grit blast to SP10 cleanliness with 3 – 5 mil angular profile.


ARC MX FG was trowel applied between 6 – 9mm (.25 – .325″) and then two alternating color coats of ARC S1PW were applied as a smoothing coat and a wear indicator coat to identify when the top 20 – 3o mils of coating have been removed.

Tack welding expanded metal mesh for increased structural integrity.


Client Reported
