The photo catalytic effect of TiO2 is well known and many mechanistic details have been investigated. TiO2 nanoparticles are the most interesting systems due to the fact that the activity depends on the available surface area and the particle diameter. The majority of the work in surface technologies mainly has been carried out on UV initiated processes. Industrial utilisation of the effect already has started for various applications, especially for self-cleaning and antifogging purposes like self-cleaning tiles, self-cleaning windows by CVD processes or self-cleaning textiles, antifogging car mirrors, and the antimicrobial effect also has been demonstrated.
Surfaces with reduced biofilm formation
The research centre combines the anti-stick function and microbiocide effect with a new technology. Thus, microbiocide surfaces with a new quality are generated.
• Layers with low surface energy;
• Very smooth surfaces;
• Colibacteria do not adhere and do not grow.
Applications: hospitals, food production etc.
New generation scratch-resistant technology
• Abrasion resistance up to 0.5 % light scatter at DIN 52347 (1000 cycles) through gradients (system dependent);
• Thermic and UV hardenable.
Applications: scratch-resistant paints as topcoat (motor vehicles among others), enamel replacement, super scratch-resistant polycarbonate spectacle lenses with further functions (e.g. UV, IR absorption or IR reflection, microbiocide effect, antistatic effect), self structuring systems for transparent viewing protection, application on all plastics and metals.
Nanocoatings with easy-to-clean functionality
• Four basic technologies: high temperature, low temperature, two-component systems as well as air-hardening systems;
• Gradient systems with adjustable fluorine gradient;
• Good adhesion on practically all substrates;
• New functions with integrated corrosion protection;
• Antistatic effect (explosion protection);
• Self-structuring layers with superhydrophobic effect.
Photocatalytic, self-cleaning surfaces
• Cooperation developments with ASTI and R-CAST, Tokyo. Planned properties of the coatings: self-cleaning, fogging-resistant, microbiocide, UV protecting. The new technology: gradient systems for plastics, made with wet coating technology.
Applications:
• Self-cleaning layers on plastics, natural stones, metals, ceramics and glass, articles of daily use, textiles
• Hygiene in hospitals and doctors' practices
• Protection against algae on house façades
• Self-cleaning façades, windows, installations, outdoor objects, sanitary facilities
• Self-cleaning windows and paints in motor vehicle construction
• UV protection paints
