DAM Härtetechnik GmbH develops boron-free and copper-free stop-off paints

A new labelling requirement for stop-off paints will take effect on 15 June 2015. Stop-off paints will then be subject to the GHS, the Globally Harmonised System of Classification and Labelling of Chemicals. But what does that mean for the products? Stop-off paints containing boron can easily be removed by washing and are made of the raw materials boron trioxide, borax and boric acid. Copper-based stop-off paints can mostly be removed by sandblasting and contain copper, copper(I) oxide or copper(II) oxide. While the first version will, in future, be labelled as toxic for reproduction within this classification, the version containing copper will be classified as environmentally dangerous. That means that the new labelling will clarify one thing: all stop-off pastes currently used in the industry or in the market pose a risk not only to the environment in general but also to the individual person. That means in a nutshell:

The currently available products pose a direct danger to humans and the environment

For more than 20 years, DAM Härtetechnik GmbH has been a worldwide active and leading company which specialises in the development and manufacturing of stop off paints for the heat treatment of steel. As a specialised company, DAM Härtetechnik GmbH is not only active in the field of development and manufacturing itself, but also offers a wide range of problem solving strategies and professional consulting services. The company reacted to the new GHS regulation with new developments. These products are used like traditional stop-off paints for gas carburising and vacuum carburising, nitriding and nitrocarburising, for plasmanitriding, annealing and oxidation, for induction hardening and brazing. The name of these new stop-off products is LUISO®. What is new is the fact that these products are both boron-free and copper-free and ensure optimal protection properties. They have, in addition, a neutral odour and do not contain any solvents. Any residues remaining after the heat treatment can be removed easily by washing with water. Even their viscosity and flow can be controlled by water. The objective behind the development of these new stop-off pastes was to strongly improve their environmental performance. And DAM Härtetechnik GmbH has achieved this objective with its new product line.

Three additional products (LUISO W30, W34 und W36) are offered for gas carburising for case depths of up to 6 mm. And the new product line also includes two products for nitriding and nitrocarburising: LUISO W21 which is ceramic-based and the LUISO W25 paste which can be used both for nitriding and nitrocarburising. The product portfolio contains, in addition, two hardness protection paints each for vacuum carburising (W44 and W45) and annealing (W61) as well as two pastes which cover the field of plasmanitriding (W51 and W53). The product offer is rounded off by a kneadable protection mass (LUISO W63) to seal off hardening boxes, small or large holes.
