Henkel develops new generation of low-dust powder products

Reduced dust nuisance on site
A cloud of dust around powder products as they are being mixed and stirred is one of the least pleasant occurrences for builders and tradesmen working on site. These blends of cement, sand and different additives are mixed with water on the spot, inevitably causing a fine dust to infiltrate the ambient air and causing nuisance to the workers and also anyone else in the vicinity. However, with the development of a completely new microgranulation technology, binding the fine particles that cause the dust to form larger clusters, Henkel researchers have now succeeded in reducing these unpleasant side-effects to a minimum, assigning dusty site atmospheres to the past.
In the vanguard of this new generation of low-dust powder products are the tile adhesives Ceresit Microgranulat Flex Plus and CM 90 and also the Thomsit smoothing compound RX 20 from Henkel. Aside from outstanding processing properties, they have been proven to reduce the evolution of fine dust by up to 90 percent compared to conventional products. This year Henkel will expand its portfolio of low-emission powder products by introducing two new joint mortars and a new waterproof slurry. So the professional user will be offered a complete range of well matched system solutions.
For the professional user, this innovative technology brings double benefits: when working with conventional powder products, craftsmen in particular are exposed to health risks every day. The cement dust often remains for a long time in the ambient air. Regular contact with relatively large quantities of cement dust can cause skin and eye irritation, asthma and even allergic reactions. With its new technology, Henkel has found a solution that will help to safeguard craftsmen against such health risks in the future. This Henkel innovation is also particularly beneficial from an economic standpoint. For fear of dirt and dust deposits in adjoining rooms, many consumers shy away from placing an order for reparation and renovation work, even in cases where the need for refurbishment is acute. Now such concerns can be completely eradicated thanks to the new microgranulate. Indeed, the newcomers under Henkel’s Ceresit and Thomsit brands are suitable for even the most delicate renovation work in department stores, museums or hotels.
The effect of the new technology can impressively be demonstrated on the basis of two glass vessels, each a quarter filled with tile adhesive or smoothing compound; one containing a conventional cement-based product and one with the new microgranulate. If the conventional product is shaken, a cloud of dust forms in the glass container which takes many minutes to settle again. In the case of the microgranulate, on the other hand, there is only a hint of dust evolution, and this settles again immediately. It is a solution that has also convinced the experts. The new Ceresit and Thomsit products have been widely acclaimed both at construction industry trade shows and by employee insurance associations in Germany. Hans-Peter Sattler, head of research and development at the site in Unna, Germany, where Henkel operates a large plant for building products, has played an active role in the development process. He is convinced: “The bigger the share of low-dust products used, the safer work will become in the construction industry. Microgranulation technology is an important milestone in achieving this aim.”
