Garrison King Fahd University of Petroleum and Minerals (KFUPM), Dhahran, KSA Abstract: Industrially-promising, waterborne latex polyurethane coatings have been prepared by emulsion polymerization of various agricultural oils including soybean, corn and linseed oils. These environmentally friendly coatings have low contents of volatile organic compounds (VOCs) compared to other coatings. As expected, the thermal and mechanical properties, as well as the long term environmental durability of the material, are shown to be highly dependent on vegetable-oil composition, processing conditions, and co-monomer chemistry. Both anionic and cationic bio-based dispersions, as well as their resulting films, were characterized using tensile testing, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical analysis (DMA). The cationic polyurethane dispersions have potential applications as coatings for food packaging materials due to their antimicrobial activities. Biography: |
