Paint & Coating Testing
Ordinary paints and coatings are susceptible to microbial attack due to factors such as organic matter composition and moisture retention. Microorganisms can cause health issues and property damage, leading to increased maintenance and repair costs. To address this, antimicrobial coatings have been developed to prevent microbial growth and control surface contamination. These coatings protect against discoloration and material degradation, enhancing the product’s shelf life. However, they must be tested for efficacy against microorganisms before being marketed.
International standards for assessing the antimicrobial activity of paints and coatings
Various international standards provide test methods for evaluating the microbial resistance of paints and coatings. These include:
- ASTM D2574: 2020 – Evaluating the antimicrobial resistance of emulsion paints
- ASTM D4783: 2021 – Determining the resistance of adhesive preparations in the container to attack by bacteria, yeast, and fungi
- ISO 21702: 2019 – Measurement of antiviral activity on plastics and other non-porous surfaces
- ASTM D5589: 2019 – Evaluating the resistance of paint films and related coatings to algal defacement
- ASTM D5590: 2021 – Evaluating the resistance of paint films and related coatings to fungal defacement
- ASTM D4300: 2023 – Determining the efficacy of adhesive films to support or resist the fungal growth
- ASTM D3273: 2021 – Evaluating the susceptibility of interior coatings to mold development
- ASTM D7855: 2017 – Determining mold growth on coated building products designed for interior applications
