History of Green VCI

VCI, also known as volatile corrosion inhibitor, comes in various chemical formulations and there are only a few recognizable VCI manufacturers today with a proven track record of R&D and investment in developing its own proprietary recipes and procedures.
 
One of the oldest VCI recipes can be traced back to the second World War era when the US military experienced severe corrosion related damages on its heavy machineries and weapons transported from the US to the Southeast Asian battlefront.

Dichan, also known as Dicyclohexylammonium nitrite, was one of the first functional VCI recipes applied as a paper coating in the mid-1940's, which eventually gave birth to the VCI industry and invention of other various types of VCI products. Dichan, therefore, is often referred to as the first-generation VCI technology but now it is rarely used because of its toxic properties.
 
Then came the notorious nitrite based VCI, which is still the most widely used VCI today and is often referred to as the second-generation VCI technology. Some of these nitrite-based VCI recipes are composed of nitrite and secondary amine-based chemicals. These chemicals, however, are considered carcinogenic and are becoming regulated.
 
As for Germany, the German Technical Rules of Hazardous Substances 615 (TRGS 615) was announced by the Federal Ministry of Labour and Social Affairs in the Joint Ministerial Gazette (GMBI). TRGS 615 restricts the use of anticorrosion agents whose use can lead to the formation of N-nitrosamines.
 
TRGS 615 states, "The content of secondary amines in finished product must not exceed 0.02% in the case of VCI packaging materials (with an active-substance content of up to 10%)" and "Every effort should be made to reduce the nitrite content to below 0.5 %".

TRGS 615 restricts the use of anticorrosion agents that can lead to the formation of N-nitrosamines. When these nitrite-containing substances are combined with amines, it produces toxic substances called carcinogens, such as Nitrosamine, when it is inhaled or in contact with the human body. VCI recipes containing either nitrite and/or secondary amines such as morpholine, sodium nitrite, piperazine, diethanolamine, potassium nitrite, etc. all fall into this category and should not be incorporated in any VCI technology in summary.

Amid concerns looming over potential health risks of these secondary amine and nitrite-based VCI products, and regulatory actions thereof by the appropriate governing bodies, green VCI, which eliminates these controversial ingredients of the nitrite and secondary amine based by 100% is what is called the third generation VCI technology – the bare minimum and new benchmark for the future VCI.
 
GreenVCI R&D Co., Ltd., a specialized VCI raw material manufacturer of the third-generational VCI technology with more than 28 years of experience in the VCI industry inherited from its parent company Eundong Industries. The company is just as experienced in global distribution of the green, biodegradable, and safe VCI for the world’s top automobile and industrial companies around the world. Since 1994, the company’s continuous investment in R&D resulted in the development of a full line of non-toxic, biodegradable, and food-grade corrosion protection products, which have also been certified by the industry’s highest test standards and certifications.
 
The global manufacturing industry stands on the brink of disruption as the ESG framework transforms the industry, along with other fourth industrial revolution factors such as AI, robotics, and digitization. Having anticipated this market trend well in advance, GreenVCI R&D Co., Ltd. developed a full green VCI product line that meets and exceeds these requirements by incorporating readily biodegradable and food-grade-chemical-based VCI recipes since the early 2000s.
 
GreenVCI R&D Co., Ltd. welcomes the opportunity to serve your company with the powerful, economical, and green volatile corrosion inhibitor solutions.
