In this study, polyurethane synthesis was carried out using the prepolymer method using the reaction of toluene diisocyanate (TDI) with palm oil-based polyols. To provide heat and anti-bacterial properties in polyurethane coatings, the addition of bentonite (B) and chitosan (K) into polyurethane samples was carried out. The concentration of bentonite and chitosan used were 1.5%, 3.5%, and 5.5%, respectively. Polyurethane-bentonite-chitosan (PU-B-K) samples were analyzed using FTIR to analyze the structure of chemical compounds. Preparation of bentonite purification was carried out by adding cetyltrimethylammonium bromide solution to the bentonite solution. The expected results in this study are the nature of the bacterial resistance produced, while to see the characteristics FTIR tests were performed. Meanwhile, to see the heat resistance TGA test will be performed.
