Trivalent Chromium Pretreatment (TCP), a Non-Toxic Corrosion Coating

Traditionally, hexavalent chromium compounds have been used to improve corrosion resistance on military assets such as planes, helicopters, and marine craft that are under constant assault from the elements. Although hexavalent chromium works well, it is a toxic carcinogen, as brought to light in the movie “Erin Brockovich” starring Julia Roberts.

A team of researchers at the Naval Air Warfare Center – Aircraft Division (NAWCAD) was tasked with developing an effective and safer alternative. After three years of research, the NAWCAD team came up with a non-toxic, comparable performing replacement known as trivalent chromium pretreatment (TCP). TCP was designed to be a drop-in replacement, which means no special equipment is needed to use it.

The NAWCAD technology transfer office, along with TechLink, contacted approximately 35 companies and provided them with data on the technology. After evaluating TCP, as well as its commercial potential, five licenses were granted to various companies, which are now generating sales in the tens of millions of dollars to commercial and military customers.

The military is now using the TCP technology to protect some of its most important assets. With recent and ongoing restrictions on hexavalent chromium, TCP use is set to expand exponentially, resulting in revenue growth, job creation, and new investment.
