Application of PU Pigment Catalyst

PU pigment catalysts are commonly used in the preparation process of polyurethane (PU) pigments. Polyurethane pigment is a high-performance coating with excellent weather resistance, chemical resistance and decorative effect, so it is widely used in various industrial fields. Catalysts play a vital role in the production of polyurethane pigments. They can accelerate the reaction rate, improve product performance, and affect the curing process of the pigment.

Specifically, the applications of PU pigment catalysts include but are not limited to the following aspects:

Curing reaction: The catalyst can serve as a curing agent to participate in the reaction process of polyurethane pigments, promoting the cross-linking reaction between the resin and the curing agent to form a strong coating.

Adjust the curing speed: By selecting different types of catalysts, the curing speed of polyurethane pigments can be adjusted to suit different production needs, such as fast curing or slow curing.

Improved durability: Catalysts can improve the abrasion, weathering and chemical resistance of polyurethane pigments, thereby increasing the life and performance of the coating.

Improve coating performance: Catalysts can also improve the adhesion, hardness, gloss and other properties of polyurethane pigments, making them more suitable for different application scenarios.
