Repellent elastomeric article

Abstract

The invention described herein includes a repellent elastomeric article with antimicrobial properties particularly useful in industrial and medical fields, such as gloves. The article contains an elastomeric base and a fluid-repellent coating composition that effectively repels both hydrophilic and lipophilic liquids from its surface and inhibits cross-contamination of surfaces. Articles prepared in accordance with the invention reduce the risk of contamination associated with blood and other body fluids, as well as reduce fluid-based visual obstruction and enhance the clarity of medical procedures. The invention also provides a method of reducing the ability of fluids to adhere to the surface of an elastomeric article.

       2 . The method according to  claim 1 , wherein the reduction in microbial adherence is greater than about 40% as measured by microbial titer of the surface of the elastomeric article.  
   
   
       3 . The method according to  claim 1 , wherein the reduction in microbial adherence is greater than about 50% as measured by microbial titer of the surface of the elastomeric article.  
   
   
       4 . The method according to  claim 1 , wherein the microbial adherence of Gram positive bacteria is reduced.  
   
   
       5 . The method according to  claim 1 , wherein the microbial adherence of Gram negative bacteria is reduced.  
   
   
       6 . The method according to  claim 1 , wherein the microbial adherence of  B. subtiles  var.  niger  is reduced.  
   
   
       7 . The method according to  claim 1 , wherein said coating composition further comprises a hydrophobic ingredient.  
   
   
       8 . The method according to  claim 1 , wherein said elastomeric article is a medical glove.  
   
   
       9 . The method according to  claim 8 , wherein said medical glove is an examination glove.  
   
   
       10 . The method according to  claim 8 , wherein said medical glove is a surgical glove.  
   
   
       11 . The method according to  claim 1 , wherein said elastomeric article comprises natural rubber.  
   
   
       12 . The method according to  claim 1 , wherein said elastomeric article comprises synthetic rubber.  
   
   
       13 . The method according to  claim 12 , wherein said synthetic rubber is nitrite rubber.  
   
   
       14 . The method according to  claim 12 , wherein said synthetic rubber is polyisoprene.  
   
   
       15 . The method according to  claim 1 , wherein said fluid repellent coating composition applied to the surface of an elastomeric article repels liquid contaminated with bacteria from the surface of the elastomeric article.  
   
   
       16 . The method according to  claim 1 , wherein said fluid repellent coating composition applied to the surface of an elastomeric article repels blood, synthetic blood, and/or a bodily fluid from the surface of the elastomeric article.  
   
   
       17 . An elastomeric article comprising an elastomeric base and a fluid repellent surface coating composition, said coating composition comprising: a) a low surface energy ingredient, wherein the elastomeric article exhibits reduced adherence of microbes to the surface of the elastomeric article compared to an identical elastomeric article without the coating composition.  
   
   
       18 . The elastomeric article according to  claim 17 , wherein the reduction in adherence of microbes to the surface of the elastomeric article is greater than about 40% as measured by microbial titer of the surface of the elastomeric article.  
   
   
       19 . The elastomeric article according to  claim 17 , wherein the reduction in adherence of microbes to the surface of the elastomeric article is greater than about 50% as measured by microbial titer of the surface of the elastomeric article.  
   
   
       20 . The elastomeric article according to  claim 17 , wherein the microbial adherence of Gram positive bacteria is reduced.  
   
   
       21 . The elastomeric article according to  claim 17 , wherein the microbial adherence of Gram negative bacteria is reduced.  
   
   
       22 . The elastomeric article according to  claim 17 , wherein the microbial adherence of  B. subtiles  var.  niger  is reduced.  
   
   
       23 . The elastomeric article according to  claim 17 , wherein said article is a medical glove.  
   
   
       24 . The elastomeric article according to  claim 23 , wherein said medical glove is an examination glove.  
   
   
       25 . The elastomeric article according to  claim 23 , wherein said medical glove is a surgical glove.
