Definiing Bio- Based Coatings: Composition and Key Charakterystyka

Bio- based coatings are surface-finishing systems formulated primaryly from replablee biological resources. Typical fearstocks included plant oleils such as soibeun, linseid, castor, and palm oil; natural polimers like celulose, lignin, and chitosan; starches derived from corn, potato, or cassava; and proteins extractant form from soy or casein. These raw materials are processed into binders, resins, and additives that form a continous film substrate af applicatien.

Unlike conventional petrochemical- based coatings, which often rely on high levels of vailed organic compounds (VOC), bio- based formulations are establered to minimize or eliminate these harmiful emissions.
