L3025 series is a special linear structure polyester diol, which has good fluidity at room temperature, and has excellent water resistance and hydrolysis resistance. At the same time, the polyester diol has excellent low temperature flexibility performance with excellent adhesion to polar substrates. Linear structure, good low temperature flexibility, good adhesion, low viscosity, high transparency; excellent alcohol solubility; main application: almost insoluble in water, soluble in ketones, alcohols, esters and aromatic hydrocarbons It is an organic solvent, suitable for urethane resin and UV urethane acrylate resin prepolymer. Especially suitable for water-based leather surface resin, giving excellent transparency, adhesion, softness and other properties. At the same time, the alcohol solubility of L3000 series is very good, and it is suitable for alcohol-soluble polyurethane resin. It has good compatibility with polyurethane and is mainly used in aliphatic polyurethanes. Its main function is to increase flexibility. It can be used in the preparation of polyurethane acrylic oligomers, as well as in waterborne polyurethane dispersions and solvent-based systems.
