Ymer™如何提高PUD性能

Ymer™ is Perstorp's range of nonionic dispersing monomers specifically designed for waterborne PUDs. 可提供三个等级- Ymer™N90, N120, and N180 - these monomers provide different levels of hydrophilicity to adjust the final properties of the coatings. 

Ymer™N90 

Ymer™N90 is designed to impact softness and 灵活性 to the final product. Its long ethoxylation chain enhances steric stabilization, resulting in high shear-thinning viscosity, 优秀的pH值, 电解质稳定性. It offers excellent ethanol resistance, making it ideal for 应用程序 requiring 灵活性 and resistance to solvents.

Ymer™N120

As the middle ground among the Ymer™ grades, Ymer™N120 provides a balance of properties. It offers medium viscosity, good shear stability, and satisfactory freeze/thaw stability. This grade is suitable for a wide range of 应用程序, delivering a soft finish while maintaining good mechanical properties. 

Ymer™N180

Ymer™N180 is tailored for 应用程序 requiring 硬度 and durability. Its short ethoxylation chain results in low, Newtonian viscosity and best freeze/thaw stability among the grades. This monomer provides high König 硬度, making it ideal for robust coatings that withstand tough conditions.

Overall, the global market for waterborne polyurethane dispersions is poised for growth. As manufacturers continue to innovate and improve the performance characteristics of PUDs, 它们的采用率预计会上升, providing versatile solutions to meet the evolving needs of the market. Perstorp's Ymer™ series of dispersing monomers represents a significant advancement in PUD 侦探hnology, offering the 灵活性 to customize coatings to precise specifications. Whether the need is for softness and 灵活性 or 硬度 and durability.
