Abstract

In this work, nine new binder compositions were synthesized based on a cycloaliphatic epoxy matrix (EP) modified with methylene diphenyl diisocyanate (MDI) and polydimethylsiloxane rubber (PDMS) with different ratios of components. The modification of the composition was confirmed by IR and NMR spectroscopy. A correlation was established between hardness, contact angle and coating composition based on binder data. Fillers such as muscovite mica and titanium dioxide were introduced into the composition of the developed binders to evaluate the physical and mechanical properties of the coatings. The influence of curing conditions (hardener, curing temperature) on the physical and mechanical properties of the coating was studied. The corrosion resistance of coatings was assessed using electrochemical methods. The weather resistance of the filled composition EP-10MDI-10PDMS was studied under humid tropical climate conditions. The coating composition is EP-10MDI-10PDMS with fillers (muscovite mica, \({\text{Ti}}{{{\text{O}}}_{2}}\) ) previously synthesized biologically active substances \({\text{Cu}}\left( {{\text{II}}} \right)\) , \({\text{Zn}}\left( {{\text{II}}} \right),\) and \({\text{Co}}\left( {{\text{II}}} \right)\) complexes of tris(2-hydroxyethyl)amine (hydrometallatranes) were also introduced to enhance antifouling properties and their evaluation in the natural conditions of Nha Trang Bay (Dam Bai Bay).
