Troysan® S61 Powder is a dry-film preservative in powder form developed by Arxada (formerly Troy Corporation) to deliver long-lasting microbial protection in architectural and industrial coatings. Engineered with a blend of potent fungicidal and algaecidal actives, it is designed to prevent surface mold, mildew, and algae growth in both interior and exterior applications. Troysan® S61 Powder is compatible with a wide range of water-based and solvent-based formulations and maintains stability even under harsh environmental exposure. It is especially suited for dry-blend systems such as cementitious coatings, EIFS, renders, and powder coatings where liquid preservatives are unsuitable.
Powder Form for Dry-Blending – Perfect for systems where water or liquid additives are incompatible
Broad-Spectrum Microbial Defense – Protects against mold, mildew, and algae on coating films
High Temperature Stability – Retains efficacy through heat-curing and thermal processes
Long-Term Outdoor Durability – Withstands humidity, sunlight, and pollutant exposure
No Effect on Coating Color or Finish – Maintains visual integrity of decorative products
Extended Protection Lifecycle – Reduces need for recoating or microbial maintenance
Cementitious Coatings & Grouts – Provides durable protection against algae and fungi in dry-mix systems
EIFS & Decorative Plasters – Guards facades and exterior finishes against discoloration and microbial degradation
Exterior Paints & Coatings – Used in high-performance emulsion and acrylic paints for outdoor use
Powder Coatings – Integrated into resin-based powders to prevent fungal growth post-application
Roof Coatings & Elastomerics – Ensures longevity in coatings exposed to moisture and UV radiation
Industrial & Maintenance Coatings – Ideal for harsh environments where long-term protection is critical
