Biosafe Coating

Definition - What does Biosafe Coating mean?

Biosafe refers to a coating that protects the surface of a substrate by acting as an antimicrobial, which mitigates the growth of microorganisms. Basically, it is a coating with antimicrobial additives (organosilane). It can be in either powder or aqueous solutions form.

It is used to protect the surface of metals and other materials from microbiologically influenced corrosion (MIC).

Corrosionpedia explains Biosafe Coating

Under certain atmospheric conditions, bacteria adhere to the interface of materials. The development of the biofilms and the change in pH can influence the process of corrosion and involve other forms of corrosion. The anaerobic zone created leads to the formation of strong acids that act upon the substrate. Therefore, the byproducts and the use of the substrate as an electron acceptor constitute the corrosion process.

The formula used in the coating is determined by forming tests by subjecting the material under a microbial solution and microbes used to observe the reaction. The charge in the active polymer used in the ingredients disrupts the cell membrane of the microorganism, thus leaking out the internal parts; poisons microorganisms when they create contact with the coating.

The additives used are available in solution, spray and powder form. Biosafe coating is manufactured with the polymers added in the structure of the coating, but the additive can also be used separately as spray. The additive has no effect on the surfaces of materials, but proves to be hostile to bacteria and other microorganisms.
