Corrosion protection anticorrosion efficiency

A paint based on an epoxy-cardanol resin has been produced and then characterized in order to compare its performance (i.e. physico-mechanical properties, chemical resistance and corrosion protection efficiency) with that of paints made with unmodified epoxy resin (Aggarwal et al., 2007). It was found that the new bio-based paints show better anticorrosive properties than the unmodified paints and thus the cardanol-based epoxy resin represents an optimal binder medium for the formulation of paints. 

It should be underlined in conclusion that inhibited polymer films are an efficient rust-inhibiting means of protecting hardware and metal structures against atmospheric, hydrosulfuric, acidic, microbiological and other types of corrosion. The numerous film types and their production processes fit any customer s preference in line with the chosen preservation method, transportation or storage conditions and anticorrosion terms. 

The efficiency of polymer materials as an anticorrosion mean of protection of metal parts from corrosion can be significantly raised by modification of polymer binders using corrosion inhibitors for metals. In this case it becomes possible to realize both the barrier and inhibition mechanisms for metal protection from corrosion in the anticorrosion element. Anticorrosion polymer elements as a source of electric field can hamper corrosion processes and corrosion-mechanical wear of metal parts by the electrochemical mechanism. Realization of the barrier, inhibition and electrochemical mechanisms of anticorrosion protection with the help of polymers not only allows a profound improvement in the anticorrosion protection of metal parts but comes close to the creation of smart anticorrosion plastics and anticorrosion systems.
