Bonded coatings from Klüber now also for drinking water applications!

Munich, January 2006 - The requirements to be met by coatings for use in contact with drinking water have become considerably more stringent in recent years. Klübertop TP 38-901 is the first bonded coating to correspond to the requirements of the newly edited guideline for the hygienic evaluation of organic coatings in contact with drinking water of the German Umweltbundesamt UBA (Federal Environmental Agency). Besides existing recommendations for applications in the food-processing sector, the approval for drinking water is another step in making this bonded coating an allround product.

Klübertop TP 38-901: a bonded coating for very special needs

Bonded coatings used in the food-processing or drinking water sector must definitely not impair in any way the product with which they are in contact. All raw materials they contain must meet the pertinent requirements, the hardened coating must show no to minimum migration of substances and should be neutral in taste and odour. After all, the bonded coating remains permanently on the component, which may have contact with food products or drinking water. Best-practice manufacturing is a matter of course for bonded coatings in such applications.

The bonded coating Klübertop TP 38-901 is compliant with the regulations of the German law governing food products, associated ancillaries and animal feeds LFGB and the guideline for organic coatings for D1 and D2 seals in contact with drinking water of the German Umweltbundesamt UBA. The raw materials it contains meets the requirements of the Food and Drug Administration FDA 21 CFR § 175.300 and § 177.1520. So when you are looking for a bonded coating for components working under tribological loads that may possibly come into direct contact with drinking water, Klübertop TP 38-901 should be your first choice.

But there's more to it: Klübertop TP 38-901 is colourless, heat-setting and water-miscible. It reduces the assembly forces for sealing rings by up to 40 percent, ensures clean and simple assembly, prevents the sticking-together of sealing rings during automatic feed and enables uncomplicated handling of mass-produced small parts.

Klübertop TP 38-901 also helps users to save costs: as it only has an organic solvent content of < 4%, no VOC filter systems are required for emission reduction, and since no mixing of several components is necessary, the bonded coating will reach its destination faster, i.e. the elastomer, plastic or metal component.

Information on guideline

Until 1998, the XL recommendation of the German Federal Institute for Sanitary Consumer Protection and Veterinary Medicine (Bundesinstitut für gesundheitlichen Verbraucherschutz und Veterinärmedizin) was used for the evaluation of organic coating materials to be used in contact with drinking water. This recommendation was withdrawn in 1998 since it did no longer reflect the knowledge and technology available today and did not satisfy the more stringent safety requirements.

The new guideline was developed by the Umweltbundesamt in cooperation with KTW-AG, the German association of the paint industry, the German association for chemicals in buildings and the German association of the plastics-producing industry and serves now for evaluating coatings in contact with water destined for use by humans (drinking water) within the scope of the German drinking water regulation TrinkwV 2001, § 17 para 1.
