Knowledge of all three factors is needed to design effective products Ag Antimicrobials Technology Effectiveness of any Ag AM will depend on three factors: 1. Ag form (solubility, chemistry, size, etc.) 2. Delivery vehicle (polymer permeability, Ag release rate, surface properties, etc.) 3. Microbial environment (water content, pH, ionic nature/strength, viscosity, flow, etc.)

Silpure Formulation • Active • Specially formulated silver chemistry for controlled ion release in microbial environment (textiles) • Manufactured to specific particle size, shape and morphology for optimal surface coverage and antimicrobial efficacy
Silpure Formulation… • Binder System • Polymeric binder system to provide adhesion of silver to fabric materials • Co developed with silver technology to provide additional control of ion release for long lasting antimicrobial efficacy • Designed for optimal performance in padding processes • Compatible with a wide range of textile auxiliaries
Treated Fabric • Topically adhered • Uniform Coverage • Maximum Durability
Product Information • Target application will be 1-3% (performance dependent) • Active (silver) concentration in blended product will be 0.24% • Final goods will therefore contain between 0.0024 and 0.0072% active (24-72 ppm)
Silpure FBR-5 Performance Evaluation • Eliminates bacteria growth • Highly durable antimicrobial performance
