Polyurethane resin has several advantages in the preparation of flexo printing ink. Firstly, it can improve the hardness and scratch resistance of the ink, making it more durable and resistant to wear and tear. Secondly, polyurethane resin can enhance the adhesion of the ink to different substrates, resulting in better print quality and colorfastness. Thirdly, it can provide a smoother and glossier finish to the printed material, which is particularly important for high-end applications such as packaging and labeling. Finally, polyurethane resin can also increase the chemical resistance of the ink, making it suitable for use in harsh environments or with aggressive solvents. Overall, the use of polyurethane resin in flexo printing ink formulations can lead to improved performance and increased value for customers.
