Making Polyurethanes from castor oil with addition of Bentonite and Chitosan as coating paints on eco-friendly medical device applications

Polyurethane-based vegetable oil coatings have been used in the past few decades considering the use of petrochemical-based raw materials is a non-renewable material. Vegetable oils used such as soybean oil, palm oil, and castor oil. They have lower environmental impacts, easy availability and biode...
