Influence of isosorbide to polyurethane dispersions for wood coatings application

摘要

Biobased renewables are of high interest as they may substitute petrobased chemicals in the long-term future. Many biobased, alternative monomers are already considered into account, both in scientific researches and in commercial use. They can be divided according to their chemical nature and available sources to oils and fats, saccharides, proteins and minor components. Instead of using the natural compound itself, it is also common to modify or to break down natural resources. Amongst the saccharides, isosorbide turns up to be a suitable diol for polyester synthesizes and hence for polyester-based polyurethane dispersions to use as resins in wood coatings.
