EcoLine® 3220 and EcoLine® 3690 are two new bio-based and biodegradable coatings that were developed to replace traditional oil-based rust preventatives. Both products are designed for extended temporary protection of multimetals and, if needed, could be easily removed using a bio-based Ecoline surface cleaner/degreaser, eliminating disposal costs associated with oils.

The coatings can provide corrosion protection while being environmentally safe and completely non-hazardous. They are reportedly improved replacements for flammable solvents and petroleum-based products, and conform to NACE Standard RP0487-2000.
