AbstractWaterborne polyurethane (WDPU) comprising polycaprolactone diol and hexamethylene diisocyanate was prepared by using tartaric acid (TA) as an ionomer. WDPU was further modified with polymethyl methacrylate (PMMA). Hybrid WDPU-PMMA coatings were formed by using unsaturate end capping agents such as 2-hydroxyethylmethacrylate. WDPU-PMMA blend coatings were formed by using chain extenders such as ethylene glycol, ethylene diamine and mixed with PMMA. Thermal behavior and structural characterizations were investigated by means of thermogravimetric analysis and Fourier transformm infrared (FT-IR) spectroscopy, respectively. Chemical and solvent resistance was checked against various chemicals and solvents. Bio-stability was evaluated in CoCl2/H2O2 solution. Gloss, film flexibility, tackiness, abrasion resistance and adhesive prosperities of WDPU-PMMA coatings were also checked by applying these coatings on a leather sheet.

Waterborne Polyurethane Acrylate

By grafting carbon black (CB) with multifunctional waterborne polyurethane acrylate (WPUA), a series of environmental-friendly CB/WPUA black coatings with different CB contents were prepared in this study. The chemical structures of the products at different synthesis stages were analyzed by Fourier-transform infrared spectroscopy (FT-IR), and the influence of carbon black content on the properties of coatings was systemically investigated. The experimental results demonstrated that the WPUA/CB composite coatings with more CB contents had higher viscosities and impaired unsaturation conversions of WPUA. However, the coating containing 4 wt% of CB obtained the best water resistance and tensile strength owing to incorporate organic-inorganic structures, which is of importance for practical application.
