Abstract: This disclosure provides a process to produce a moisture-curable polyurethane binder composition comprising: providing a first mixture comprising an isocyanate-containing species and a polyol component, wherein the polyol component is a polyfunctional polyol and the isocyanate-containing species is a difunctional or polyfunctional isocyanate and wherein the isocyanate-containing species and the polyfunctional polyol are reacted to form an isocyanate-functionalized species; adding a non-ionic surfactant to the first mixture; and adding water to the first mixture to form an emulsion, wherein the moisture-curable polyurethane binder composition contains about 3% to about 25% residual isocyanate functionality.

Abstract: A composition having biocidal properties comprises pre-fabricated elastomeric particles, a biocidal agent, and an adhesive phase combining the elastomeric particles and the biocidal agent, wherein the pre-fabricated elastomeric particles and the adhesive phase are made of different materials, and wherein the biocidal agent is present in the adhesive phase but is substantially absent from the pre-fabricated elastomeric particles. Elastomeric compositions or products of this disclosure are useful to prevent communicable diseases resulting from bodily exposure to pathogenic bacteria such as Staphylococcus aureus and Methicillin-Resistant Staphylococcus aureus (MRSA) strains.
