Investigation of Mechanical, Surface and Thermal Properties of Dual-Curable Hydrophobic Coatings

One of the important coating technologies, ultraviolet (UV) light curing, is increasingly preferred with increasing application areas and advantages that are present compared to other methods. In this article, coatings were prepared using ICA (Laromer？ LR 9000) resin, an isocyanate acrylate resin, and resin systems containing monoethylene glycol (MEG), diethylene glycol (DEG) and fluoro alcohol (Fluorolink？ E10-H), a perfluoropolyether derivative terminated with dialkol. As a result of heat and UV curing of these resin systems, free films were obtained at different ratios fluorine containing and these formulations were also coated on aluminum sheets. Obtained free films; Mechanical and thermal properties were determined by tensile testing, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Furthermore, the properties of the coatings coated on the aluminum sheet determined by tests as pencil hardness test, cross-cut test, gloss test and contact angle test. When the results are examined, it is seen that a hydrophobic and bright coating is obtained. It has also been found that fluoroalcohol added at different ratios has different effects on the mechanical properties of the structure containing diethylene glycol with the structure containing monoethylene glycol
