Veneer is the material of plywood that has higher resistance (psi) depending on wax coat (W1, W2, W3) and temperature (T1, T2, T3). In an experiment, a large thin wood panel sheet will be coated with a wax coat. This will then be divided into three portions where each will be subjected to a drying temperature. After processing, several sheets will then be pasted together, and the resistance will be measured. Two manufacturing companies will participate in the experiment with two runs for each company.
