Biosan hygiene coatings for walls, ceilings and floors afford simple and safe protection against bacteria. They provide seamless, easy to clean surfaces and high efficacy through incorporation of anti-bacterial technology. Biosan is completely safe in use.

Introduction
Biosan hygiene coatings when used in conjunction with standard hygiene procedures give added security against bacteria.
They provide a high quality, seamless surface that is easy to clean and very durable. Biosan is provided with second generation anti-bacterial carrier technology Bactron™ to ensure its antibacterial efficacy during the normal service life of the coating.
Applications
Biosan has particular significance for application in hospitals and other health care facilities, pharmaceutical industry facilities, food processing facilities such as dairies, kitchens, breweries and abattoirs, leisure centres and schools.
Authority Biosan is registered in the UK with the HSE and NPIS and deemed to be BPD product type 2. This places it in the same category as most common detergents and cleaning materials.
The active ingredient of Bactron™ is not classified as harmful to humans but is a very effective agent against bacteria. It is widely used in toothpastes and disinfectant soaps. The active ingredient is approved for transient food contact in the USA and EU.

DESCRIPTION
Bactron™ surrounds and partly penetrates the resin and pigments of the Biosan coating. Bactron's active ingredient kills most types of bacteria by a variety of different mechanisms including the ability to penetrate cell walls thus inhibiting growth and reproduction. Biosan coatings are supplied as the following 4 low odour products:
Biosan Aqua is a single pack, water-based acrylic coating ideal for walls and ceilings in low wear areas. It has excellent flow and levelling properties with high coverage.
Biosan Aqua Plus is a 2 pack, solvent-free coating designed for walls and ceilings where high abrasion resistance is required. It is easy to clean with excellent opacity.
Biosan Ultra is a 2 pack, solvent-free floor coating where high abrasion resistance is required. It is easy to clean with excellent opacity.
