Economic and Environmental Impact of Traditional Rust Preventives as Compared to Novel Biobased Temporary Coatings

摘要

Biobased temporary rust preventatives are gaining market share due to their low cost, effectiveness and excellent environmental profile. Traditional petroleum derived rust preventatives require expensive degreasers and hazardous disposal methods, while biobased products are inherently biodegradable and in most cases do not require removal before painting or welding. Additionally, today's trends in automotive industry move towards sustainable and renewable materials which make USDA certified, biobased, temporary rust preventatives an excellent alternative for petroleum derived coatings. This paper includes comparative experimental testing of biobased and petroleum based rust preventatives in humidity chamber according to ASTM D-1748. The corrosion protection efficiency was determined using polarisation techniques according to ASTM G5-94 on Potentiostat/Galvanostat 273A EG&E.
