Cortec releases USDA-Certified Biobased Product

22 January 2020

Cortec® Corporation, a leading corrosion inhibitor manufacturer committed to using sustainable materials where possible, has launched the EcoLine® 3690, a U.S. Department of Agticulture- (USDA-) Certified Biobased Product that can be used to replace solvent- and mineral-oil based (RPs).

U.S. federal agencies and their contractors must meet special biobased requirements when purchasing products from 139 categories identified by the USDA. One of these is corrosion preventatives, which must have 53% minimum biobased content to be a qualified product under the mandatory federal purchasing initiative of the USDA BioPreferred® Program. 

EcoLine® 3690 is a ready to use canola-oil-based temporary coating designed for corrosion protection in severe marine and high humidity conditions. It contains 72% USDA-certified biobased content and leaves behind an oily protective film that does not dry. It is best for contractors who manufacture parts or equipment for the federal government and need to prevent rust in interim periods of storage or shipment. It is also good for any manufacturer around the world who wants to go to the next level of sustainability while reducing VOCs and minimizing worker exposure to mineral-oil or solvent-based RPs. EcoLine® 3690 can be easily removed with an alkaline cleaner and can help users avoid hazardous waste disposal costs associated with traditional rust preventatives.

For best results, EcoLine® 3690 should be applied to clean metal surfaces by spray, roll, brush, or dip at a recommended WFT (wet film thickness) of 1.0 to 3.0 mils (25 to 75 μm). It can also be applied over painted surfaces. EcoLine® 3690 has no VOCs and is temperature stable up to 180°F (82°C). It protects multiple metal types, such as stainless steel, carbon steel, aluminum and copper.
