Esters with Antimicrobial, Bioresistant and Fungal Resistant Properties

Abstract

A bromine/nitro moiety linked into the backbone of an ester or other compound over a wide range of occurrence rates provides antimicrobial, bio-resistant and fungal resistant properties for metal working fluids (MWF)s and other coatings. The moiety can be have the bromo and nitro groups linked to the same or different carbon atoms. The present invention also relates to urethanes, urea, amides, imides, carbonates, ethers, siloxanes, and many other types of linkages essential to MWF bases.

1 . A molecule comprising at least one bromo-nitro group covalently bonded, said molecule having the formula: 
       
         
           
           
               
               
           
         
         where R and R′ are the same or different and are independently chosen from the group containing polysiloxane, linear or branched, saturated or unsaturated, alkyl, alkenyl, alkylamine, alkylamide, alkylquat, alkanol, ether, polyether, arylalkyl, carboxylic acid, ester, polyester, and ketone. 
       
     
     
         2 . A metal working fluid base comprising a molecule according to  claim 1 . 
     
     
         3 . A surfactant comprising a molecule according to  claim 1 . 
     
     
         4 . A foaming or anti-foaming agent comprising a molecule according to  claim 1 . 
     
     
         5 . The molecule of  claim 1  wherein the occurrence rate of the bromine and nitro group is greater than 1.
