BIOMASTER™ AT 300
for water-based coatings
Biomaster™ AT 300
Biomaster™ AT 300 is an active odour control technology based on silver salt, a highly effective and naturally occurring anti-bacterial agent. It stops odour-causing bacteria from settling into any material. Without bacterial growth, there is no odour. Biomaster™ AT 300 is Oeko-tex® classes i-iv, EPA and bluesign® approved.

Evaluation of Biomaster™ 300 AT in water-based paint
Basic Properties

Results
To test the effectiveness Biomaster™ AT 300 in water-based coatings, our Regional Coatings Innovation Center conducted a side-by-side comparison with a white-based paint incorporating 0.5% Biomaster™ AT 300, and one batch of paint without the additive.
The results indicate that the paint containing 0.5% Biomaster™ AT 300 can destroy bacteria faster than without. We tested Biomaster™ AT 300’s efficiency for both E.coli and Staphylococcus aureus and the reduction of colony forming units (CFUs) was significantly increased with the addition of Biomaster.
Furthermore, the addition of Biomaster™ AT 300 in white-based paint does not affect basic paint properties, i.e. viscosity, pH, density, opacity, gloss.
The recommend dosage for Biomaster™ AT 300.
How Biomaster Works


Biomaster™
To reduce the spread of bacteria, surfaces need to be easy to clean and hygienic to minimize the risk of cross-contamination. If you can build in effective antimicrobial protection at the manufacturing point, this can be even easier and faster to integrate into a wide range of industries including healthcare, food and catering, public transport, packaging and more. Addmaster’s Biomaster™ does exactly this. By being added to any plastic, textile, paper, paint, or coatings at the point of manufacture, it provides durable product protection from bacterial growth.
