Abstract
Prepared polyurethane resin for buffalo leather coating on surface was synthesized with addition reaction glycerol which had different mole ratio. Mechanical properties of the synthesized polyurethane resin were measured by the SEM, FT-IR, UTM. Growing concerns in the evnironment-friendly polymer resin, we have synthesized low late obtained solvent water dispersion resin to be coating on buffalo leather. The increase of aliphatic trihydric alcohol glycerol mole %, abrasion resistance and tensile strength had demonstrated reduce properties. On the contrary, elongation and flexibility properties had highly increased. In the result of toluene solvent resistance, there was no effect of increased or decreased by the ratio of glycerol mole %.
