Introducing VpCI® 423, an advanced water-based gel specifically designed for the efficient removal of rust and oxides from various metal surfaces, including steel, iron, brass, and copper.

This innovative gel offers a safe and effective solution to prevent corrosion without causing any harm to most common material substrates.

One of the remarkable features of VpCI® 423 is its ability to cling onto vertical and overhead surfaces, making it ideal for tackling rust and oxide build-up in hard-to-reach areas. Moreover, the formula incorporates flash corrosion inhibitors that effectively prevent flash corrosion during the rust and oxide removal process.

After applying VpCI® 423 and completing the rust removal, thorough rinsing with water is recommended. Following that, to ensure a clean and corrosion-free metal surface, consider utilising Cortec® VpCI® 414 or similar alkaline cleaners.

As an additional advantage, VpCI® 423 is NSF (A3) registered, making it suitable for indirect food contact applications. The product proudly boasts a 91% USDA-certified biobased content, aligning with sustainable practices and meeting the criteria for Mandatory Federal Purchasing in the USDA BioPreferred® program.

Typical Applications

VpCI® 423 finds widespread utility across various industries due to its versatility in combating rust and corrosion-related challenges. The typical applications of this advanced product include highly effective in-process rust removal for metal parts and stock. Whether it's in automotive, marine, or manufacturing equipment, VpCI® 423 proves to be an indispensable asset for safeguarding valuable assets against rust and ensuring their prolonged lifespan.


VpCI® 423, a versatile rust remover and corrosion inhibitor, finds numerous applications across various industries. This exceptional product can be conveniently applied using conventional or airless spray equipment, as well as by using a brush. Its straightforward application process starts with preparing the surface by removing any loose or flaking rust. Once the surface is adequately prepared, VpCI® 423 is applied to the affected areas.

Upon application, the unique formula of VpCI® 423 begins to work its magic, penetrating and dissolving rust, effectively converting it into a protective barrier against further corrosion. To ensure optimal results, it is recommended to allow the product to stand on the surface for approximately 10-15 minutes, during which the VpCI® molecules create a protective layer.

After the recommended dwell time, the surface can be easily cleaned by rinsing it with Cortec® VpCI® 414 or a similar alkaline cleaner. The combination of VpCI® 423 and VpCI® 414 enhances the overall protection and effectiveness of the treatment, ensuring that rust and corrosion are effectively removed and inhibited.
