Epoxy coating

In this work, nano-SiO2 have been used as nanocarriers for loading Ce(III) ions (SiO2@Ce3+). After loading, silane coupling agent has been used to modify these nanocarriers (m-SiO2@Ce3+). Then, these modified nanocarriers were added as green inhibitors into the inner epoxy coating matrix, which was based on the epoxy resin (DER 671X75) and hardener (polyamide Epicure 3125). Morphological study by FE-SEM showed that the spherical nanoparticles (mSiO2@Ce3+) were in size < 100 nm and dispersed rather homogeneously into the polyme matrix.

The influence of the black seed oil modified epoxy resin (EBSO)/monomer 3,4-epoxycyclohexylmethyl 3,4- epoxycyclohexane carboxylate (BCDE) weight ratio in the coatings based on the compounds and photoinitiator triarylsulfonium hexafluoroantimonate (TAS) on thermal properties of photocrosslinked coatings have been studied. The chemical structure of investigated UV-cured coatings was characterized by IR spectrometric analysis. Their thermogravimetric (TG) and differential scanning calorimetry (DSC) behavior were determined by TG and DSC analysis, respectively.

The epoxy ester was prepared from epoxy resin DER 331 and fatty acid by esterification reaction in inert gas without catalyst. The kinetics of the esterification was investigated and the results shown that the temperature, reaction time and mol ratio of epoxy resin to fatty acid suitable to electro-deposition process are 220o C, 150 minutes and 1/4, respectively. The received epoxy ester was modified with 15% (wt%) maleic anhydride at 175o C for 120 min which was adapt to binder for anodic electro-deposition coating.

This study is focused on the synthesis of a polyindole doped by indole-3 butyric acid (PI-IBA). IR analyze indicated that the linkage positions of indole involves the position 2 and 3 of the monomer and the insertion of IBA in the polymer backbone. Polyindole IBA doped was incorporated into epoxy resin for protection anticorrosion of carbon steel. The electrochemical impedance measurements show a significantly improvement of protective properties in presence of PI-IBA in comparison with pure epoxy and epoxy containing polyindole coating.
