Antimicrobial Paints & Coatings

Additives for water based, solvent based & 100% solids coatings, as well as pre-qualified powder paints​

SteriTouch antimicrobial additives are available for any type of coating, including decorative paints, powder coats, solvent based, water based & 100% solids coatings.

At relatively low addition rates, these additives will provide excellent antimicrobial efficacy without adversely affecting the physical performance of the coating.

Antibacterial Acrylic Paint

Why use antimicrobial additives in your paint?

Using an antimicrobial paint additive in a new or existing formulation is a simple way to add value and differentiate your products. Antimicrobial paints containing SteriTouch additives have been independently proven to prevent the growth of bacteria for 10 years, as well as offering ongoing protection against black mould and algae.

In many cases it can be as straightforward as mixing the additive into the paint to achieve a long lasting antimicrobial effect, and solutions are available for most coatings. Through our partnerships, we are also able to supply pre-validated paints for most applications, from domestic emulsions through to highly resistant scrubbable acrylics for very demanding environments such as operating theatres.



We have additives for most paint & lacquer types, including water-based, solvent-based and 100% solids.


Suitable for resins including nylon, polyester, polyurethane and epoxy without affecting colour or curing time.



Polyester, epoxy-polyester and nylon-modified powder paints in any RAL colour and gloss level, or as a clear coat for substrates such as brushed stainless steel. Moving from a standard powder to a pre-validated SteriTouch powder is as simple as changing the box. Our antimicrobial powder coats are applied using conventional equipment, and require no processing changes, meaning a SteriTouch antimicrobial coating can be added to existing products with minimal effort.



An essential part of any antimicrobial development, our services include ISO22196, ISO21702 and ASTM G21 testing.


Paints & Coatings FAQ

A few of the most commonly asked questions... please contact us if you need more information...

What colour & gloss level powder paint can you provide?

Any colour, any gloss level. We can also supply textured finishes and can colour match an existing paint.

If we use your powder paint, or one of your paint additives, can we use the SteriTouch trademark?

In most cases, yes. Any customer utilising the powder paints we supply would be able to use the SteriTouch trademark. When using an additive, then provided an acceptable level of performance is maintained, the trademark is likely to be available too.

How easy is it to mix the additive into my coating?

Most of the additives are supplied as liquids and are therefore very easy to disperse into a paint or lacquer. Some of the additives are supplied as powders, which would need to be dispersed by high-shear mixing. In some instances, we can pre-disperse powder additives into suitable liquid carriers .

How much additive do I need to use?

This depends on a number of factors, such as the type of paint, the environment in which it will be used, the target organisms and the type of additive, but it would typically be in the range of 0.5% to 2% by weight of solids.
