Abstract

The article describes the methods for the preparation of two new generation biocide additives, namely zinc oxide immobilized on graphene oxide and a complex biocidal additive based on polyhexamethylene guanidine immobilized on montmorillonite, and their application in two-component polyurethane coatings, which differ in both the polyol and isocyanate components. The antimicrobial activity of these additives against Aspergillus flavus ATCC 9643, Staphylococcus aureus ATCC 6538, and Candida albicans ATCC 9027 has been studied. The coatings were applied by aerosol spraying of solutions in volatile solvents. The adhesion to steel substrate (peel resistance) and hardness of the polyurethane coatings containing these additives were also evaluated. IR spectroscopy was used to compare polyurethane coatings with different polyol components. This method has been used to investigate the interaction between the additives and the components of the reaction system. The effectiveness of biocide additive in polyurethane systems was compared.
