Transforming PU Tactile Paper Coatings with Polycarbodiimide Crosslinkers
Transforming PU Tactile Paper Coatings with Polycarbodiimide Crosslinkers Enhancing the tactile experience while maintaining quality and durability is a constant challenge for paper manufacturers. Polyurethane (PU) tactile paper coatings have long been a popular choice for adding a luxurious and distinctive feel to various paper-based products. However, like any coating system, they come with their […]
Application of Anti-hydrolysis Agents in Polyester Polyols and Polyurethanes
Polyurethane (PU) is usually prepared by the reaction of isocyanate or terminal NCO prepolymer with polyol or polyamine. Among them, polyol is the main raw material in polyurethane chemistry. According to different monomers, synthesis processes and molecular structures, polyols can also be divided into two major categories: polyether and polyester. What is polyol? Polyol, also […]
Application of polycarbodiimide in PUDs
Polycarbodiimide is a versatile and multifunctional polymer that has been widely used in various applications, including in polyurethane dispersions (PUDs). PUDs are water-based coatings that are widely used in the production of various products, such as textiles, leather, wood, and automotive coatings. Polycarbodiimide is used in PUDs as a crosslinking agent, which helps to improve […]
Improve the performance of water-based polyurethane with carbodiimide crosslinker
With the introduction of various environmental protection policies and the enhancement of consumers’ awareness of environmental protection, water-based products have gradually become the future development trend of coatings and adhesives. Take water-based polyurethane as an example, it has the advantages of traditional polyurethane such as flexibility and low-temperature resistance. Since its main dispersion medium is […]

How to improve the chemical resistance of water-based wood paint using one-component PUD and PUA?
Polyurethane dispersion (PUD) is the main category of water-based industrial paint. Polyurethane dispersion (PUD) is composed of polyurethane particles dispersed in the water phase by an organic solvent or dispersant. It has good film-forming properties and can provide excellent appearance and hardness. PUD has no residual isocyanate and can be formulated with low VOC. It can be used more safely […]
The five factors affecting waterproof performance of waterborne polyurethane coatings
Waterborne polyurethane waterproof coating is a new type of polymer waterproof coating. Waterborne polyurethane coating has a serious disadvantage. Because it uses water as a dispersant, it will inevitably introduce hydrophilic groups such as carboxyl and hydroxyl groups into the molecular structure. Its water resistance is much worse than solvent-based polyurethane coatings. There are generally […]
