“…After the test, all the coatings showed strong resistance to MEK and no solubility occurred on the coating surface. Gloss 60• test were applied for brightness measurement of the coatings [9,10]. This property is very important for decorative coatings.…”

In this study, fluorine chains were bonded with covalently in epoxy acrylate system via UV light. For this purpose, five different coating samples prepared. Bisphenol-A glycerolate diacrylate (epoxy acrylate) and 1,6-Hexanediol diacrylate were used as the main coating solution. The weight ratio of Bisphenol-A glycerolate diacrylate and HDDA was determined as 7/3. As a long fluorine chain, 1H,1H,2H,2Hperfluorodecyl acrylate (PFOA) was added into the main coating solution in the ratios of 0.25 wt %, 0.50 wt %, 0.75 wt % and 1 wt %. All prepared solutions were coated on aluminum plates by 75 µm by wire wound applicator and then cured via UV dryer. Physical properties of coatings were measured by tests such as MEK rubbing test for solvent resistance, gloss 60 o test for brightness, cross-cut test for adhesion property and pencil hardness test for scratch resistance. Hydrophobicity was measured as static water contact angle test. The total surface energy was calculated by contact angle measurement software. In terms of mechanical properties, sheen impact test (for coating samples) and ShoreD hardness tests (for free film samples) were carried out. By examining the results of all these tests; cross-cut adhesion and gloss 60 o values decrease with the fluorine content. On the other hand, by the increasing within the content of the fluorine chains, Taber abrasion resistance and hydrophobicity increase significantly but sheen impact resistance and ShoreD hardness values decrease slightly. In terms of cost and overall results, the most proper and multifunctional coating seemed at 0.25 wt %.

“…Moreover, as the fluorine content increased in the formulations, the hydrophobicity of the coatings increased. This behavior of fluorine‐containing polymers is explained by the segregation of the fluorinated segment on the surface and, thus, creates a hydrophobic surface .…”

“…In the sol–gel method, organic and inorganic species combine at a molecular level; due to the synergism between the organic and inorganic domains, it is possible to prepare inorganic–organic hybrid coatings with enhanced properties, such as resistance to scratching and abrasion and thermal stability . Generally, fluorine is incorporated into these hybrid coatings via two ways: (1) with the use of fluorinated acrylic precursors or (2) by using perfluorinated alcohols/alkoxysilanes in sol–gel reactions . In the literature, there are several papers discussing the preparation of fluorine containing hybrid coatings.…”

In this study, fluorine-doped photocurable hybrid coatings were prepared by combining UV-curing technology with an anhydrous sol-gel method. First, methacryloxymethyl triethoxysilane (MEMO) was hydrolyzed via an anhydrous sol-gel process. Then MEMO was mixed with acrylic oligomers and predetermined amounts of fluoroacrylate resin. UV curable hybrid coatings were applied on corona-treated plexiglass substrates. The addition of fluorine showed a significant impact on the properties of the coatings. As the fluorine content was increased in the formulations, flame retardancy and the contact angle values of the coatings increased. It was found that the optical transmittance of the coatings was higher than 95%. The surface morphology of the hybrid films was characterized by scanning electron microscopy (SEM). The chemical composition of the surface of the coatings was identified by energy dispersion spectrum (SEM-EDS) technique. SEM studies indicated that inorganic particles were dispersed homogenously throughout the organic matrix. J. VINYL ADDIT. TECHNOL., 21:272-277, 2015.

This study describes the synthesis of silane terminated urethane, aimed at adding into epoxy acrylate, for the coating purposes. For this aim, firstly, silane terminated urethane was synthesized by the reaction between poly(hexamethylene carbonate) diol and 3-isocyanatopropyltrimethoxysilane. Pre-hydrolyzed TEOS and MEMO mixture was added to the silane terminated urethane. This solution was then mixed with organic part (epoxy acrylate and HDDA) to obtain hybrid solutions. Different organic-inorganic hybrid formulations were applied on polystyrene sheet surfaces by using applicators. The performance of the coatings on polystyrene sheets was investigated by applying physical and chemical tests. The results have shown that physical and chemical properties of polystyrene sheet surfaces were significantly improved.
