“…The subsequently dramatic decompositions occur in the second stage ranging from 250 to 370 °C, which is attributed to the destructions of strong chemical bonds such as urethane bonds. The third stage arranges from 370 to 450 °C, and the weight loss can be ascribed to the decompositions of the rigid groups such as carbamido and benzene ring structures . Here, the corresponding temperatures [inset in Figure (b)] of 5% weight loss ( T 5% ) and maximum weight loss ( T max ) are both used to further discriminate the heat stability properties of PUA resins.…”

In this article, aiming to develop the high performance ultraviolet (UV)-curable resin used in the polymer matrix composite, a series of polyurethane acrylate (PUA) resins with the different numbers of allyl terminal groups were elaborately designed and synthesized, in which the contents of hard segments and soft segments were also adjusted simultaneously. The effects of allyl number on properties of PUA were systemically investigated. It was found that allyl number had the negligible effect on the processability as well as positive effect on thermal performances, and all PUA resins exhibited the low viscosity and rapid UV polymerization. Besides, with the change of allyl number in the range of 2-4, PUA resin casting with three allyls possessed the preferable mechanical properties such as 85.1 MPa tensile strength, 3.94 GPa tensile modulus, and 20.7 kJ m −2 impact strength. More importantly, the high strength and high modulus of the composite further demonstrated the wide potentials of the as-prepared PUA resin as the ideal resin matrix candidate for the fiber reinforced polymer composites.

“…There has been a growing interest in the coating and printing industry to develop environmentally friendly coatings or printings, as consumers have become more conscious about environmental issues and more stringent environmental legislations have been implemented in the world (Kim et al , 2017). Moreover, solvent-based raw materials used in coating and printing industry contain organic solvents which pollute atmosphere and lead to severe health problems in humans.…”

“…Polyurethanes (PUs) have been commonly employed in adhesives and coating industries. In recent years, water-borne PUs have attracted much interest and are expected to replace their solvent-based counterparts (Kim et al , 2017). Radiation curing technology, such as UV curing system, has some advantages like space saving, energy efficiency, reliable and fast curing compared to thermal systems (El-Molla, 2007; Li et al , 2018).…”

PurposeIn this study, it is aimed to synthesize ultraviolet (UV)-curable water-borne polyurethane acrylate (WPUA) binders using different types of polyols (poly (propylene glycol), PPG1000 and PPG2000 and poly (ethylene glycol), PEG1000 and PEG2000) at different molecular weights, DMPA (2,2-bis(hydroxymethyl) propionic acid) at different amounts and isophorone diisocyanate (IPDI) and use for pigment printing on synthetic leather.Design/methodology/approachUV-cured films were characterized by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimeter (DSC). The effect of binder structure on printing performance was determined with hardness, crock fastness, abrasion resistance and color measurements.FindingsThe highest abrasion resistance (60,000 cycles) and crock fastness values (dry crock and wet crock: 3/4) were obtained with binder PEG-C synthesized with PEG2000 and lower DMPA amount of 4.89 wt%; however, PEG-C binder showed lower hardness values. Due to lower urethane groups in PEG-C binder, more flexible films were obtained which imparted good adhesion property to printing film. Synthesized binders provided lower crock fastness and abrasion resistance properties than commercial WPUA binder.Originality/valuePigmented formulations including UV-curable water-borne synthesized PUA binder were developed and for the first time applied onto synthetic leather using screen printing method. Within this context, a new environmentally friendly printing method was proposed in this study including binder synthesis in the preparation of printing formulations.
