Used as leather finish
The film-forming material in the coating layer has a great influence on the physical properties of the finished leather, especially the top coating gives the finished leather surface water resistance, solvent resistance, mechanical scratch resistance and other properties, which play a decisive role in the appearance of the leather. Due to the introduction of hydrophilic ionic groups into the molecular chain of polyurethane, the water resistance of its coated leather is poor. This shortcoming can be improved by adding hydroxy silicone oil. Hydroxy silicone oil is a kind of material with good hydrophobicity, air permeability and weather resistance. When it is used in the synthesis and modification of water-based polyurethane, the leather obtained after finishing will have better wet rub resistance and smoother hand feeling. Comfortable.

Used as a leather back sealer
When some leather back covers are painted, the coating will peel off because the coating is not resistant to the impregnation of the solvent in the shoe adhesive. Hydroxy silicone oil can be used for its good air permeability, weather resistance, corrosion resistance and non-toxicity. Effectively solve the peeling phenomenon when the back cover is painted.
