Box-Behnken method for enhanced performance of solvent-based epoxy coatings reinforcement with diatomite/surfactant/zinc borate

Abstract

This study is aimed to improve the properties of the organic coatings by adding additives of various properties to industrial organic coatings with epoxy resin and to obtain organic coatings with superior properties. Boron end-product, methacrylate-based fluorinated liquid and diatomite additives have been added to the epoxy resin-containing organic coatings in the specified proportions (0-6% (w/w)). The Box-Behnken optimization method has been applied on the metal surface. The surfaces where the organic coatings are applied are subjected to various tests (adhesion, corrosion etc.) in accordance with the standards. According to the test results, coatings are resistant to impact, corrosion, high adhesion resistance, gloss and covering values. In addition, as a result of Thermogravimetry/Differential Thermal Analysis (TG/DTA), flame retardancy is improved, more homogeneous structures are obtained by adding additives with Scanning Electron Microscopy (SEM) analysis, hydrophobic property is improved according to the contact angle and surface free energy measurement results. Consequently, it has been observed that additives added to the organic coatings in various proportions improve the organic coating in terms of flame retardancy, surface properties and hydrophobicity. It is envisaged that the organic coatings with new properties can be preferred in different industries.
