Compositions providing physical biocide synergist activity in paints, coatings, sealants and adhesives during storage

Abstract

This invention relates to the use of an N-alkylethanolamine or N,N-dialkylethanolamine wherein each N-alkyl group is independently a C 3 through C 12 straight chain or branched alkyl group, the substituted ethanolamine is used in combination with a biocide for the anaerobic shelf stabilization of a latex paint, uncured coating, uncured sealant, uncured adhesive or related product.

1 . The use of a compound having the formula:  
       RR′NCH 2 CH 2 OH and/or RN(CH 2 CH 2 OH) 2    
       wherein R is a straight chain or branched alkyl group having 3 to 12 carbon atoms and R′ is hydrogen or a straight chain or branched alkyl group having 3 to 12 carbon atoms which is the same or different from that of R, in combination with a biocide for stabilization of a stored latex paint, uncured coating, uncured sealant, uncured adhesive or related product.  
     
     
         2 . The use of an N-alkylethanolamine or N-alkyldiethanolamine wherein the N-alkyl group is a C3 through C12 straight chain or branched alkyl group in combination with a biocide for the stabilization of a stored latex paint, uncured coating, uncured sealant, uncured adhesive or related product.  
     
     
         3 . The use of an N,N-dialkylethanolamine wherein the two N-alkyl groups are C3 through C12 straight chain or branched alkyl groups which may or may not be the same in combination with a biocide for stabilization of a stored latex paint, uncured coating, uncured sealant, uncured adhesive or related product.  
     
     
         4 . A stored latex paint, coating, sealant, adhesive or related composition containing an N-alkylethanolamine or N-alkyldiethanolamine wherein the N-alkyl group is a C3 through C12 straight chain or branched alkyl group in combination with a biocide.  
     
     
         5 . An uncured latex paint, coating, sealant, adhesive or related composition containing an N,N-dialkylethanolamine wherein the N-alkyl groups are C3 through C12 straight chain or branched alkyl groups that may be the same or different in combination with a biocide.  
     
     
         6 . The composition of  claim 4  wherein the alkyl group is butyl, isopropyl or amyl.
