Abstract

Waterborne 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.
