Cortec introduces bio-based anticorrosive WB acrylic coating
Last update on Jan 28, 2026
Cortec is announcing a major step forward in the development of bio-based anticorrosion coatings for metal with the release of EcoLine® 3860, Cortec’s first water-based acrylic coating to incorporate renewably sourced resins. EcoLine® 3860 contains 27% USDA certified bio-based content and is designed for industrial users who want to increase their use of renewable content. It is an important move toward expanding sustainable options in the specialty field of corrosion inhibiting paints.

Protecting metals while reducing VOCs
EcoLine® 3860 is an extension of Cortec’s line of VpCI®-386 anticorrosion coatings, which have become flagship products in the Cortec portfolio of corrosion solutions. VpCI®-386 represents the journey from solvent-based technologies that once dominated the market to water-based paints that can effectively protect metals from corrosion while reducing VOCs and introducing other user benefits. Over the last several decades, VpCI®-386 has become a mainstay of Cortec® coatings, demonstrating the potential for preservation with reduced environmental impact.
With the release of EcoLine® 3860, Cortec is poised to follow this pattern in the field of bio-based paints for corrosion inhibition. Once again, acrylic paints provide a good starting point for metals protection because of their flexibility, good adhesion, and UV resistance. As typical for Cortec® coatings, EcoLine® 3860 remains well within Green Seal and EPA guidelines for low VOC coatings, registering at 0.6 lbs/gal (72 g/L). Applied clear or matched to a range of custom colors at a DFT (dry film thickness) of 1.5-3.0 mils (38-76 µm), EcoLine® 3860 offers an unobtrusive way to add corrosion protection to metal parts, equipment and structures while introducing renewable content.
As Cortec’s first bio-based acrylic anticorrosion paint, EcoLine® 3860 represents an important milestone in the use of bio-based resins, setting the stage for the development of more advanced bio-based anticorrosion coatings in the future.
