With its worldwide availability and its low market-price native starch provides the potential for the use as a bio-based material. However, in its native form it is highly hydrophilic, not cold-water dispersible and only forms brittle films. So, our work aimed at the chemical modification of the structure of native starch for reaching cold-water dispersible hydrophobized starches with high solid contents (≥ 30 % (w/w)) and viscosities between 100 and 1000 mPa·s which form continuous films for the application in the coating sector as binder, with a focus on paints and varnishes.
