Founded in December 1994, Metalast International, LLC (MILLC) was a "green" metal finishing technology company that provided its customers with a wide range of R&D, technical support services, process control computers and more than one hundred (100) metal finishing specialty chemicals serving the aluminum anodizing and corrosion control industry. Its founder and MILLC manager for 20 years (1993 to 2013) was David M. Semas (Semas), Chairman of Metalast International, Inc. (MII), incorporated in May 1994.

​

Beginning in 2004 MILLC became a licensee of the United States Naval Air System Command (NAVAIR) and was one (1) of only three (3) companies, MILLC, Henkel and SurTec licensed to bring to market and commercialize Navy TCP (Trivalent Chromium Process). Navy TCP is a patented environmentally friendly chromate conversion coating technology developed to replace hexavalent chromium, a known carcinogen made famous in the movie "Erin Brockovich.”​​  

 

In 2006 MILLC entered into a manufacturing and sub-licensing agreement with a business unit of one of the world's largest global chemical conglomerates for the production and commercialization of its Navy TCP licensed product line formulated and marketed under the Metalast® TCP-HF (hex free) brand.

Since 1996, "METALAST® is a federally registered trademark owned exclusively by David M. Semas. Under a federal court approved settlement agreement since June 10, 2015, Chemeon Surface Technology, LLC, and no other Chemeon distributor, nor any person or company has been licensed or authorized to use, reference, or describe any product or formulation as “formerly METALAST®.” Any such representation is unauthorized and may constitute trademark infringement or false designation of origin. These restrictions were further adjudicated by the United States District Court, of Nevada (Reno), including an injunction prohibiting unauthorized use of the METALAST® trademark, name and brand with the District Court’s judgment affirmed by the United States Court of Appeals for the Ninth Circuit in May 2024.

 

Where unauthorized use or misrepresentation of the Metalast® trademark or product brand identity involves Department of Defense procurement, NAVAIR Qualified Product List (QPL) certifications, defense contractors, aerospace, and aircraft manufacturers, or other federally regulated supply chains, the legal implications may extend beyond trademark infringement and civil liability.

 

If evidence establishes that individuals, Chemeon or any other company knowingly and willfully misrepresented material facts to government officials, including product brand identity, manufacturer authorization, or qualification status in connection with federal procurement, such conduct could potentially constitute violations of federal false-statement, fraud, or procurement statutes, exposing responsible parties to civil enforcement actions and, where the statutory requirements are satisfied, criminal prosecution. Any determination of liability would depend upon the specific evidence, applicable law, and findings by the Department of Justice or other appropriate federal authorities.
