Abstract

Polyurethane coating materials are widely used in waterproofing construction because they ensure easy workability and high performance mechanical properties, and such polyurethane coating materials are in various mixture ratios. This study carried out a test to determine the basic physical property changes of polyurethane coating material based on the amount of charcoal additives to. The results showed that he tensile strength was found to be 3.1 N / ㎟ when the charcoal amount was at 2%, displaying the highest performance rate.
