In the finishing agent is the main component of the film forming agent. Leather finishing, requirements of film forming agent strong adhesion, flexibility and extensibility and flexibility should be consistent with the leather; at the same time, the film itself should have the gloss, abrasion resistance, water resistance and breathability, acid and alkali chemical reagent.

In recent years, foreign in leather industry generally using silicone as leather finishing materials (silicone smoothing agent for leather).
