Abstract

The composite coated by some materials coaters have been made. This coating was done to isolate the fungus possibly growing on the composite. The composite was made from a mixture of teak leaves waste and polyurethane polymer using a simple mixing method; then the mixture was pressed at a pressure of 3 metric-tons for 15 minutes. The composite produced then was coated with acrylic only and acrylic-silica using spray method. The coated samples then were characterized using scanning electron microscopy (SEM) to determine the surface pores. Further, it was obtained the average surface pore size of acrylic coater is 1.24 μm, while the acrylic-silica pore forms an oval shape with a length and a width of 0.75 μm and 0.38 μm, respectively. In comparison with the fungus size of 2-7 μm, it can be concluded that the composite is proper as home appliance application.
