“…Due to the high chromate toxicity for human beings and environment, the use of these compounds will be banished in 2017 in the aircraft sector. Many studies concern the development of new technologies and alternatives aiming at avoiding the use of chromate: sol-gel coatings [7][8][9][10][11], new anodizing layers [12][13][14][15] and elaboration of organic-, inorganic-or hybrid coatings [16][17][18][19]. Epoxy resin coatings are generally used as organic coatings to prevent corrosion of aeronautic structures due to their good mechanical properties, strong adhesion, high crosslinking density and excellent chemical resistance [20,21].…”

“…28 Glycidyl methacrylate (GMA)-based copolymers successfully entered the eld of epoxy resin technologies due to the ease of copolymerization with other matrices 29,30 and the possibility to prepare homogenous or heterogeneous polymer networks with tailored properties. 33,34 In this work the aforementioned lms have been engineered and combined in a high performance multilayer coating. In previous studies the concentration of surface free radicals, generated during PPF growth, was optimized to guarantee a successful initiation of free radical polymerization of an acrylate.…”

In the context of a universal search for alternatives to chromate-based coatings, which are toxic for both human beings and the environment, a multilayer coating for Al protection purposes is developed and investigated in the current work. The first layer is selected to be a hexamethyldisiloxane-based plasma polymer film (PPF), deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD), due to a number of interesting features that are characteristic of plasma polymers. The second layer is synthesized via the polymerization of the 2-ethylhexyl acrylate monomer initiated from the free radicals trapped on the surface of the PPF during its growth. A subsequent layer of a copolymer of 2-ethylhexyl acrylate and glycidyl methacrylate, poly(EHA-co-GMA), is deposited by spin coating to increase the corrosion resistance of the coating. An improvement in the anti-corrosion properties of the multilayer coating by approximately three orders of magnitude as compared to the uncoated Al substrate is observed. Further enhancement of the adhesion and scratch resistance properties is addressed via UVcrosslinking and the incorporation of in situ generated silica nanoparticles into the final layer.

Four multialkoxy-functionalized siloxane base-polymers (BP-1~4) were synthesized through either hydrosilylation or condensation reactions in order to prepare multi-networked siloxane polymers having appropriate physical properties for protective coating in fabrications of electronics. Formulations of 4 base-polymers gave coating materials A and B. Product A showed well-controlled flowing and leveling properties, and product A-2 was successfully applied to protective insulating coating for junction areas of connectors and chips in PDP controller. Tack free time, extrusion rate, dielectric breakdown voltage, hardness, thermal stability, water resistance and flame resistance of products A and B were examined.
