Synergistic palm-based polyurethane system for 2D decorative ink

Abstract

The recent palm oil crises have stimulated many researchers to utilize the palm oil and palm kernel oil, and turn them to non-food value-added products. The formulated ink was invented as a solvent-based two-component polyurethane system with an average viscosity of ~ 69 cps, making it easily flows and suitable for decoration purpose. It is compatible with any kind of water-based pigments available in the market. It has high water-resistance, fire-resist, thermally stable and cost-effective by doing some test which are TGA test, FTIR test, viscosity test and hardness test. A polyurethane with a ratio of 1:0.4:1 is the most optimum ratio of polyol to MDI to PEG due to its thermal stability, low hardness index, uniform cellular structure and less curing time.
