摘要：
An antimicrobial composition is formed from about 5 to about 25 wt % of an antimicrobial formulation and about 75 to about 95 wt % of a polyurethane resin or polyurethane hybrids, copolymers, or mixtures with other polymers such as polyesters, nitrites, PVC, and synthetic rubber latexes. The antimicrobial formulation is formed from about 60 to about 90 wt % of an antimicrobial material, about 1 to about 30 wt % calcium chelator, about 0.001 to about 2 wt % color and appearance enhancing pigments, about 0.001 to about 2 wt % of surfactants, and about 0.5 to about 10 wt % lubricant. The polyurethane resin may be a nonaqueous or aqueous latex dispersion or a prepolymer that polymerizes when exposed to moisture. An antimicrobial coating may be formed on the surface of an article by applying an antimicrobial composition to the article; if a polyurethane prepolymer is used, the composition is exposed to moisture and if an aqueous or nonaqueous dispersion is used, the water or solvent is evaporated. A coating may also be formed by making a mixture of the antimicrobial formulation and a resin and molding, overmolding, or extruding the article from the compounded mixture.
摘要（中）：
抗微生物组合物由约5至约25重量％的抗微生物制剂和约75至约95重量％的聚氨酯树脂或聚氨酯混合物，共聚物或与其它聚合物如聚酯，亚硝酸盐，PVC和合成物的混合物形成 橡胶胶乳。 抗微生物制剂由约60至约90重量％的抗微生物材料，约1至约30重量％的钙螯合剂，约0.001至约2重量％的颜色和外观增强颜料，约0.001至约2重量％的表面活性剂 ，和约0.5至约10重量％的润滑剂。 聚氨酯树脂可以是非水性或水性胶乳分散体或当暴露于水分时聚合的预聚物。 可以通过将抗微生物组合物施用到制品上而在制品的表面上形成抗微生物涂层; 如果使用聚氨酯预聚物，则组合物暴露于水分，如果使用水性或非水性分散体，则蒸发水或溶剂。 还可以通过制备抗微生物制剂和树脂的混合物并且从配混的混合物中模制，包覆成型或挤出制品来形成涂层。
