French company Kerneos, based in Dunkerque, is celebrating 40 years of existence.
It specialises in high alumina cement, which was patented in 1908, and is said to be a world leader in the field.
France accounts for just 10% of the market, while the largest client is Germany.
The high-end cement is notably used in luxury boutiques, as well as in the hangars of Airbus and car assembly lines.
The company has launched a new high alumina cement called Ternal RG-S, dubbed an anti-wrinkle cement.
