              ABSTRACT

              In this study, the use of silicone based chemicals were investigated as water repellent agent for the production of medium density fiberboard (MDF). Two different chemicals (Dow Corning 87 and Xiameter PM-200) were applied to fibers by spraying together with melamine ürea formaldehyde resin (MUF) in different proportions (0.5%, 1.0% and 3.0%). Addition to the water uptake and swelling properties, the change in the tensile strength, bending strength and elasticity modulus of MDFs were investigated.

              The results showed that fiberboards produced with these chemicals had lower water absorption and swelling in thickness compared with MDFs produced with only MUF resin. In addition to closing the hydroxyl groups of the fibers, the water repellency hydrophobic structure protects the fiber-fiber bonds against water. It was found that fibreboard produced with these chemicals had better tensile strength, bending strength and elastic modulus depending on addition level.
