  • a coalescent agent was added in an amount of 6 % by weight to a commercially available styrene-acrylate latex (Dispersion A) (Tables 5 & 6), or to a commercially available polyvinyl acetate latex (Dispersion B) (Table 7), followed by determination of the mould inhibition activities of these mixtures made of the coalescent agent and the dispersion according to the method.
  • mould inhibitor containing from 7 to 10 % by weight of 3-iodo-2-propynylbutyl carbamate and from 3 to 5 % by weight of 2-(methylthio)- 4-(tert-butylamino)-6-(cyclopropylamino)-s-triazin was added in an amount of 1.5 % by weight.
  • mould inhibitor containing from 7 to 10 % by weight of 3-iodo-2-propynylbutyl carbamate and from 3 to 5 % by weight of 2- (methyl thio)- 4-(tert-butylamino)-6-(cyclopropylamino)-s-triazin was added in an amount of 1.5 % by weight.
