AI Overview
Dry film antimicrobial preservatives are specialized biocides added to paints, coatings, adhesives, and construction materials to prevent fungal, mold, and algae growth on surfaces after application. These additives ensure long-term, low-leaching protection against moisture-driven deterioration.
Key Aspects of Dry Film Preservatives:
- Protection Type: Primarily target surface fungi, molds, and algae.
- Application Areas: Exterior paints, interior coatings for high-moisture areas (bathrooms/kitchens), and wood coatings.
- Key Properties: Effective dry-film preservatives offer high leaching resistance, thermal and pH stability, and low solubility to ensure the agent remains on the surface.
- Key Suppliers/Brands: Arxada (Omadine®, Densil®), Janssen PMP (Zinc PYRION®).
Why They Are Essential:
- Aesthetic & Physical Durability: Prevents staining, discoloration, and degradation of coatings.
- Health and Safety: Protects against mold growth in modern airtight buildings, which is linked to poor indoor air quality and "sick building syndrome".
- Prevention of Economic Loss: Protects against costly reworks due to early failure.
