Agrob Buchtal’s Hytect is a highly effective and durable coating, which involves Titanium Dioxide (TiO2) being durably and inseparably baked onto the ceramic surface at high temperature. This treatment acts as a permanent catalyst and triggers a life-long reaction activated by light (photocatalytic) with oxygen and humidity. The reaction results in the release of activated oxygen and gives rise to a highly hydrophilic ceramic surface. The hydrophilic surface drives the first function listed below, whilst the activated oxygen generates the remaining 2 functions:
- The hydrophilic surface forms a microscopic film of moisture over the panel, preventing the build-up of dirt and grime and facilitating an easy to clean lining surface
- Pollutants such as nitrous oxides react with the activated oxygen and are transformed into harmless compounds
- Decomposes fungi, algae, moss and inhibits growth

- Antibacterial Effects – The activated oxygen that is released at the surface of the Hytect ceramics have been shown to decompose a range of harmful microorganisms such as bacteria, moulds and fungus. As microorganisms such as bacteria, fungus and mould come into contact with the ceramic surface or commence growth on the surface, the activated oxygen decomposes the microorganisms and continually impedes the growth of new microorganisms.

These beneficial effects have been scientifically documented in reports prepared by German scientific laboratories.
Protecta Surface Upgrade
Agrob Buchtal has introduced Protecta surface upgrading to improve stain and dirt resistance in high foot traffic areas such as shopping centres, airports and aquatic centres.
The Protecta upgrade is applied as part of the manufacturing process causing the pores within the ceramic to close. In this way, the penetration of substances forming stains is prevented.
Products with Protecta surface upgrade are marked with the Protecta symbol.
