preparation mechanical properties and surface morphologies of waterborne fluorinated polyurethane acrylate
Progress in Organic Coatings, 2013Co-Authors: Yingying Wang, Fengxian Qiu, Yan Jiang, Dongya YangAbstract:Abstract A series of waterborne fluorinated polyurethane-acrylate (WFPUA) materials were prepared from polyester polyol (NJ-330), isophorone diisocyanate (IPDI), dimethylol propionic acid (DMPA) and different content of hexafluorobutyl acrylate (FA). The chemical structure was characterized with FT-IR, 1 H and 13 C NMR; and the result confirmed that the FA monomer had been introduced into the chain of the WPUA polymer. The physical properties of WFPUA dispersions, mechanical properties and thermal properties of WFPUA films were measured. When the content of FA monomer was 3.0 wt.%, the film exhibited the highest tensile strength, hardness and excellent chemical resistance. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) were used for characterization of cross and surface sections of the WFPUA films to verify the results. The obtained WFPUA materials have great potential application such as Coatings, leather finishing, adhesives, sealants, Plastic Coatings and wood finishes.

Waterborne Polyurethane-Acrylate Containing Different Polyether Polyols: Preparation and Properties
Polymer-plastics Technology and Engineering, 2012Co-Authors: Dongya Yang, Qing Guo, Yingying Wang, Fengxian QiuAbstract:The waterborne polyurethane–acrylate (PUA) was prepared based on isophorone diisocyanate, polyether polyol, dimethylol propionic acid, hydroxyethyl methyl acrylate, butyl acrylate (BA) and styrene (St). Fourier transform infrared spectrometry (FT-IR), Ultraviolet-visible spectrophotometry (UV-Vis) and Differential scanning calorimetry (DSC) were employed to investigate the structures, optical transparency and thermal properties. Some physical properties of the aqueous dispersions such as viscosity, particle size and surface tension were measured. Some mechanical performances and solvent resistance of films were investigated. When the ratio of the BA/St was 30/70, the films had excellent water and alkali resistances. The obtained PUA composites have great potential application such as Coatings, leather finishing, adhesives, sealants, Plastic Coatings and wood finishes.

a critical review of the quality and safety of badge based epoxy Coatings for cans implications for legislation on epoxy Coatings for food contact
Critical Reviews in Food Science and Nutrition, 1998Co-Authors: Jesus Simalgandara, Senen Pazabuin, Lennart AhrneAbstract:BADGE-based epoxy resins have been commercially available for more than 40 years. They are extremely versatile, finding applications in many fields in both thermal and ambient cure applications. The present review focuses on their use in the food industry as surface Coatings for food and beverage cans, and in particular on their chemical stability in relation to their toxicology and sensorial effects on foods. The implications of these properties of epoxy resins for prospective EU legislation on Plastic Coatings for food contact is discussed.
