About DAM Härtetechnik
DAM Härtetechnik GmbH develops and produces ceramic-based carburizing protection pastes under the LUISO® brand, which act as Stop off Paints to protect targeted component surfaces against unwanted carburization, nitriding, oxidation or coating. The product range covers gas and vacuum carburizing, nitriding and nitrocarburizing, plasma nitriding, annealing and oxidation, as well as brazing and PVD coating. In addition to standard variants, the company offers boric acid-free and copper-free formulations that meet the requirements of the REACH regulation – including LUISO® W35 for deep case carburizing up to 6 mm case depth with uniaxial application and LUISO® W30 for case depths up to 1.5 mm, whose residues can be removed with water or a steel brush. The products are manufactured in Germany (Made in Germany). The company advises customers in person on selecting the appropriate, regulatory-compliant carburizing protection solutions for their heat treatment processes.
