Conventionally, polyurethane has been mainly used as a coating material or impregnation material in the production of synthetic leather. This is because the excellent elasticity and physical properties of polyurethane are suitable for synthetic leather materials.

General polyurethane synthetic leather is produced by polymerizing 20 to 80 parts by weight of a solid component obtained by polymerizing an urethane raw material polyol, chain extender and isocyanate in an organic solvent such as dimethylformamide or methyl ethyl ketone, and having a viscosity of 50,000 to 150,000 cps / 25 ° C polyurethane is used as impregnation material and coating material to produce synthetic leather, and there are dry method and wet method.
