Passivation and Special Coatings
Cleaner Surfaces.
Smarter Protection.
Less Downtime.
Standard cleaners and passivation chemistries often miss the mark—requiring hours of cleaning, corrosion issues, or downstream rework.
Circle-Prosco’s custom-formulated cleaners, passivation, and protective coatings are built to meet the specific demands of your production line, whether you’re cleaning internal heat exchanger tubing or applying protective finishes that hold up in harsh environments.
Built for the Complexities of
Modern Manufacturing
Combat corrosion
from the inside out
Internal passivation and cleaning chemistries designed for aluminum and stainless steel systems.
Protect exposed
surfaces
External and nanoscale conversion coatings designed to improve corrosion resistance, manage moisture, and meet OEM specs.
Tailored to your
substrates and specs
Custom blends for aluminum and steel alloys—formulated to meet performance and compliance requirements.
Speed from
prototype to production
Circle-Prosco delivers coatings fast, with rapid lab development and scalable launch plans.
