How to Evaluate Antimicrobial Paint Additives
Developing antimicrobial paints and coatings starts with the material, manufacturing process and intended application. An antimicrobial additive can be incorporated into suitable materials to inhibit microbial growth on the treated material. Suitability, processing requirements, test evidence and permitted claims need to be assessed for the finished application.
Define the material and application
Record the coating chemistry, cure conditions, film thickness, colour and gloss requirements. Evaluate the proposed additive in the complete formulation; do not assume performance or compatibility transfers between paint systems.
Plan formulation and manufacturing trials
Discuss the specification with Addmaster before selecting an incorporation approach. Agree the material, process conditions, sample requirements and success criteria, then evaluate representative trials. Record any change to appearance, processing or other product requirements alongside the intended Biomaster function.
Agree relevant testing and responsible claims
Choose a test programme appropriate to the treated material and intended application. ISO 22196 may be relevant to suitable plastics and other non-porous surfaces; it is not a universal test for every material. Laboratory results must not be presented as evidence of preventing infection or transmission. Agree permitted claims for the product and its sales markets.
Discuss your development requirements
Share the material or formulation, manufacturing process, intended application, sales markets and available sample or test information with Addmaster. These details help establish an appropriate next step for the development project.
Evaluate the complete coating system
An additive is evaluated within a coating formulation, rather than in isolation. A useful trial records the binder system, pigment package, application method and cure schedule alongside the proposed treatment. Compare appearance, adhesion and the other properties required by the coating specification. Where those properties matter to the application, agree how they will be assessed before samples are produced.
A laboratory sample and a production-applied coating may experience different processing and curing conditions. Keep the trial conditions representative of the intended process, and record changes between sample preparation and scale-up. This makes the resulting evidence more useful when deciding whether to proceed.
Compare trial samples against agreed requirements
Set the acceptance criteria before reviewing the results. Compare representative samples with an appropriate reference and record the preparation conditions. Include the intended Biomaster function alongside the appearance, processing and product properties that matter to the application. A positive result for one requirement does not remove the need to assess the others.
If a trial does not meet the agreed specification, review the material, formulation and process with the development team before changing several variables at once. Keeping a clear record of each iteration helps identify what needs further investigation and which results can reasonably support the next decision.
Move from trial results to a manufacturing decision
Review the evidence as a complete development record. Confirm which material, process and sample conditions were evaluated, what the results show and which questions remain open. Where a production-scale trial is needed, agree its scope and the information required before committing to the next stage.
Commercial planning should also consider sample availability, manufacturing requirements, validation work and the intended launch markets. Discuss those requirements with Addmaster so that the development route reflects the product rather than a generic additive specification. A clear enquiry makes it easier to establish the appropriate technical discussion.
Prepare your enquiry to Addmaster
For a paints and coatings project, provide the material or formulation, manufacturing route, intended component, target markets and key product requirements. Include representative sample information and any existing test results where available. Explain the development stage and the decision you need to make next.

Frequently asked questions
What information is needed before a development trial?
Provide the material or formulation, manufacturing process, intended application, target markets and product requirements. Include any existing test results and sample information.
Does the same approach suit every material?
No. Suitability and the incorporation and validation programme depend on the material, processing route and intended application. Discuss the specific requirements before making a formulation decision.
Discuss your paints and coatings development project with Addmaster. Share your material, process, application and target markets so the team can review an appropriate next step.
