Colonial Coatings Earns Approval for Alseal 5KST Chrome-Free Protective Coating

Milford, CT – February 2026

Alseal 5KST is now officially part of our approved capabilities at Colonial Coatings Inc. We are proud to announce that Coatings For Industry (CFI) has certified us as an approved applicator for Alseal 5KST, their advanced chrome-free protective coating system. This approval came on November 18, 2025, after we successfully completed their required qualification trials.

This milestone allows us to offer Alseal 5KST as a reliable, environmentally friendly solution for high-performance corrosion protection.

What is Alseal 5KST? Alseal 5KST is a multi-layer, chromium-free aluminum-ceramic coating system from Coatings For Industry. First, it uses a sacrificial basecoat for excellent corrosion protection. Then, sealers and topcoats enhance durability and high-temperature resistance (up to 1100°F / 593°C). Importantly, Alseal 5KST contains no hexavalent chromium, no known carcinogens, no HAPs, and no VOCs. As a result, it serves as a greener alternative to traditional chromate-based coatings. Therefore, it suits demanding applications like gas turbine components, compressor airfoils, and other ferrous alloy parts in harsh environments.

Benefits for Your Projects With this approval, we deliver proven chrome-free protection that meets strict industry standards. You gain:

  • Superior corrosion resistance
  • High-temperature durability
  • Environmentally responsible application

Whether for turbine parts, industrial hardware, or other critical components, Alseal 5KST from Colonial Coatings provides tested, consistent quality.
