COTECH Bio Safe™ With Built-In Antibacterial Product Protection

COTECH Bio Safe™ is an Anti-Fingerprint (AFP), easy to clean, and hard-wearing coating that keeps metallic surfaces looking pristine throughout their life and service. When applied to surfaces, COTECH Bio Safe™ not only cuts the need for replacing possessions prematurely due to tarnish and wear but also eliminates the need to polish notoriously hard-to-clean surfaces. This helps save precious time and money on both replacement of materials and the cost of cleaning chemicals. To cater for more hygiene-critical applications, COTECH Bio Safe™ also features built-in Microban® antibacterial technology.

Untreated coating succumbs to degradation caused by bacterial growth

Treated coating is protected against bacterial proliferation

Blended into the coating at the stage of manufacture, Microban® silver technology works to continuously inhibit the growth of bacteria on the surface of the coating. It does this by disrupting the vital life processes and biological functions of bacteria, meaning they cannot grow or reproduce and subsequently die. The result is a surface coating that stays hygienically cleaner and fresher in-between cleaning. It is also easier to keep clean.

COTECH Bio Safe™ is already utilised in a variety of hygiene-critical public spaces, including offices, train carriages and retail stores.

"We decided that when it came to choosing our partner within the antimicrobial additive market, there was only one choice that stood head and shoulders above all else, that being Microban, for their global expertise, scientific backup and service."

COTECH Bio Safe™ Used and Trusted by UK Train Operators

In August 2020, Coatings Tech received Railway Approvals accreditation for its Bio Safe™ coatings product for use on all UK railways.


The coating will be applied to all external parts of a train carriage, including doors and handles, helping to deliver hygienic surface protection against unwanted bacterial growth. Coatings Tech expects to extend this application to carriage interiors in due course.

In February 2022, Coatings Tech announced that East Midlands Railways had chosen to utilise COTECH Bio Safe™ on all toilets within its fleet.
