Tuning the mechanical performance and adhesion of polyurethane UV cured coatings by composition of acrylic reactive diluents

Synthesis and Characterization of Green Polyurethane Coatings Derived from Niger‐Seed‐Oil‐Based Polyesteramide Polyols

“…The nature of applied coatings has been assessed with the viscosity of resins [ 43 ] and it also examined the rheological properties. It could affect the coating thickness, adhesion, film formation, spreading ability, and leveling.…”

Light-responsive polyurethanes: classification of light-responsive moieties, light-responsive reactions, and their applications

“…In addition, PU is known for excellent weathering and chemical resistance of the coating and is usually used in a wide range of UV-curable coating materials. 81,123,124 Using different forms and concentrations of the reactive diluents, the adhesion, mechanical, and physical properties of the PU are possibly modied without altering the composition of the PU coating system. Zvonkina et al reported on a UV-curable PU coating from the aliphatic difunctional urethane oligomer, functional acrylic reactive diluent, and a mixture of photoinitiators, i.e., Irgacure 184 and Irgacure 819.…”

“…Zvonkina et al reported on a UV-curable PU coating from the aliphatic difunctional urethane oligomer, functional acrylic reactive diluent, and a mixture of photoinitiators, i.e., Irgacure 184 and Irgacure 819. 81 The photopolymerization mechanism was employed in the lm form of PU. The polymerization process was examined by measuring the heat ow under UV light irradiation (light source: Omnicure Series 2000 device, 160 W, wavelength: not reported) and was assessed by exothermic enthalpy during the photopolymerization process.…”

Design of polymeric composite materials for coatings and sealants with increased weather resistance

“…Актуальним завданням є підвищення стійкості по-криттів до різноманітних руйнуючих факторів в умовах експлуатації [19][20][21]. Автором [22] було досліджено підвищення атмосферостійкості поліуретанових матеріа-лів шляхом формування поверхневого шару з розчинів насичених високомолекулярних каучуків.…”
