Surface Printing Ink

PU resin, also known as polyurethane resin, is a type of synthetic resin that is widely used in the production of inks. It is a versatile material that offers various benefits for ink formulations.

One of the main advantages of using PU resin in ink is its excellent adhesion properties. It forms a strong bond with different substrates, including paper, cardboard, plastic, and metal, ensuring that the ink adheres well to the surface and resists smudging or rubbing off.

PU resin also provides good gloss and transparency, resulting in vibrant and visually appealing prints. It enhances the color intensity and clarity of the ink, making it suitable for high-quality printing applications.

In addition, PU resin offers excellent resistance to water, chemicals, and abrasion. This makes the ink more durable and long-lasting, ensuring that it remains intact even under harsh conditions.

Furthermore, PU resin can be formulated to have fast drying properties, allowing for faster production speeds in printing processes. It also has good flexibility and elasticity, which helps prevent cracking or flaking of the ink film.

Overall, PU resin is a popular choice for ink formulations due to its excellent adhesion, gloss, transparency, resistance, and drying properties. It is commonly used in various printing applications, including packaging, labels, decals, and graphic arts.
