New Levels of Protection in 1K, Water-Borne, Direct-to-Metal Coatings

June 22, 2021

CLEVELAND, Ohio – Lubrizol Performance Coatings announces the commercial availability of Aptalon™ M8120 Polyurethane Dispersion (PUD), enabling coating formulators to deliver powerful performance in one-component, water-borne coating systems for direct-to-metal (DTM) applications.


Aptalon M8120 uses patented Aptalon™ Polyamide Polyurethane chemistry to deliver a self-crosslinking, water-based resin technology as an outstanding alternative to many solvent-based coating technologies:


  • 5B Adhesion  –  while typical polyurethane dispersions often require a primer for optimal adhesion, Aptalon M8120 delivers outstanding adhesion performance as part of a single coat DTM application
  • Hardness and Abrasion Resistance  – far exceeding other water-borne DTM coating systems, Aptalon M8120 provides excellent durability and protection that lasts
  • Corrosion Performance  –  the advanced Aptalon M8120 PUD provides very good endurance in salt spray testing conditions
  • Chemical Resistance  –  Aptalon M8120 is designed to deliver excellent resistance to a broad range of chemicals common in industrial and other harsh environments.
  • Low VOC  –  Aptalon M8120 provides these performance capabilities for water-based coatings as low as 230 g/L VOC (US Method) / 100 g/L VOC (EU Method), significantly lower than many similar-performing solvent-based coating technologies


“End users of industrial and protective coatings are always looking for ways to simplify application while maintaining coating performance,” shares Nick Sterne, marketing manager. “And we’ve seen increased interest in single coat solutions that reduce the number of steps in the coating process. Coatings formulated with Aptalon M8120 realize many benefits because it delivers all of the protective properties of a high-end PUD without any need for a primer coat on metal surfaces.”

Lubrizol Performance Coatings is a market-driven innovator of specialty chemicals for advanced coatings, composites and inks that enable the world to Move Cleaner, Create Smarter, and Live Better. Aptalon M8120 delivers on that promise, helping formulators attain solvent-based coating performance in safer water-borne, low VOC systems that apply easier and protect longer.
