Leather finishing is generally divided into three parts:Primer coat, middle coat, and topcoat.Primer requires strong adhesion, hiding power, good embossing formability and stereotyping, and the middle coating further covers and modifies the color, and finally achieves the visual and physical performance requirements through the topcoat.With a specific topcoat, the effect of extinction or light can be created.

Waterborne polyurethane resin is the main material commonly used in leather coating. Its film forming performance is good, the bond is firm, and the coating has the characteristics of high wear resistance, high elasticity, water resistance, weather resistance, cold resistance, chemical resistance and so on.After finishing, the finished leather feels full and comfortable, which improves the grade of the finished leather and plays a role in protecting the leather.

In order to meet customers' pursuit of quality and meet the most stringent environmental requirements,SinograceChemical launched two single-component waterborne polyurethanes, which are polymerized from aliphatic isocyanates.Excellent adhesion, good adhesion resistance, comfortable feel, no yellowing, good weather resistance. The products are widely used in leather shoes, belts, sofas and luggage leather and other leather products. For leather top finish to provide excellent gloss and permeability, excellent wear resistance and weather resistance.
