NanoTechnology for excellent surfaces



Welcome to GBneuhaus GmbH, your competent and reliable partner for innovative coating solutions. Our strength lies in the combination and ongoing refinement of coating materials and coating methods on the basis of modern nanotechnology. We specialise in small parts in the glass and plastics sector as well as in substrates made of ceramics or metal.



SANIT, short for for Sanitärtechnik Eisenberg GmbH, is a company in the international sanitary industry whose products are exported to more than 70 different countries all over the world. Originally founded as a handicraft business, SANIT has developed into a modern and successful company in the more than 70 years of its history. SANIT produces and sells modern products for front-wall installations, drain fittings, pipe aerators, toilet accessories, basins, bathroom fittings and swimming pool grates.

With its extensive range of toilet flush plates SANIT sets accents that convince the customer at first sight. Whether plastics, thermoset, glass or stainless steel – their high-value materials ensure appealing and long-lasting comfort. Whether with lighting, infrared, cable or radio release - the possibilities are almost limitless. Since the SWING flush plate from SANIT is in great demand, especially in public and semi-public areas - for example also in clinics or age-appropriate facilities - SANIT was looking for a partner for the application of an antimicrobial surface.

SWING, made of brushed stainless steel, is coated with SANPURE® by GBneuhaus, as this preserves the high-end look and appealing feel of the flush plate without any compromises. Thanks to added fluorescence particles, the coating can be made visible in UV light and can thus still be detected after a long time. Thanks to SANPURE®, SANIT’s SWING flush plate has an undisputable competitive advantage in the market. At SANIT, they are aware of the added value this joint project brings: "Thanks to GBneuhaus, our products can meet the current requirements of the market and ensure greater hygiene in the bathroom and toilet.”

Founded in 1936 as a producing company for industrial metals, DOM Sicherheitstechnik GmbH & Co. KG is now one of the leading manufacturers for innovative locking systems and digital entrance control systems in the world. The product range extends from practical solutions for the safety of single-family houses to modern digital entrance control systems for large buildings. 

To satisfy the people´s clearly extended awareness for hygiene in these days, DOM searched for a partner who is able to develop and applicate an antimicrobial coating. Numerous researches have shown that silver is the only chemical element that fights mould, bacteria, viruses and fungus, says Georg Schweyen, Quality Management Officer of DOM Sicherheitstechnik GmbH & Co. KG. Based on a study of the German Ministry of Education and Research silver already indicates an antimicrobial effect when using only small particles. The silver is killing up to 99.9 % of the dangerous microorganisms. The topic was to realize this solution on the door handles and knobs of DOM.

Coating the door handles and knobs made of stainless steel has been realized without a problem. Developing an individual solution for the knobs made of fine zinc alloy was more laborious because the coating couldn´t stick to this material that easily. Thanks to the enormous knowhow of the R&D department at GBneuhaus, a fitting primer system that creates the basis of liability and guarantees long-term effectiveness of SANPURE® could also be found for this material.

"With the years of experience of GBneuhaus in innovative coating of metals with a coating solution whose main component is nanosilver it has been possible to make our digital door handles and the knobs of our digital locking cylinders hygienically safe.", finds Georg Schweyen, Quality Management Officer of DOM Sicherheitstechnik GmbH & Co. KG.
