Abstract:
1. A process for producing an antimicrobial polyurethane foam comprising: providing an aqueous polyol component; adding an antimicrobial metallic compound and a complexing agent to form a complex that is soluble in the aqueous polyol component; solubilizing the antimicrobial metallic compound complex in the aqueous polyol component to form a stable blend; mixing a multi-functional isocyanate component with the stable blend; reacting the multi-functional isocyanate component with the aqueous polyol to form a polyurethane foam incorporating the antimicrobial metallic compound; and allowing the complexing agent to dissipate such that the antimicrobial metallic compound is present as substantially only the antimicrobial metallic compound in the finished foam.
