The contraction of infection from equipment is a recognised risk in the healthcare sector, office and education establishments and public buildings. It is essential to take precautions to reduce the risk of bacterial cross contamination.

Here at 3D Lockers we can provide an effective solution to minimizing these risks. Our storage lockers have a unique anti-bacterial powder coating incorporated at the time of manufacture. BioCote antimicrobial technology offers constant protection against a wide range of bacteria including MRSA, E. coli, Salmonella, Listeria and Campylobacter.

Field tests have proven that storage equipment treated with BioCote powder coating benefit from a 94% reduction in bacteria on their surface, helping to create a cleaner and more hygienic working environment.

BioCote also helps stop the build up of ugly black mould, keeping their appearance for longer.

BioCote will not wear off or leak – it is long lasting and will retain its antimicrobial efficiency for the lifetime of a product!
