Polyurethane coatings are essential for protecting surfaces exposed to aggressive environments, especially in industries like infrastructure, marine, automotive, and industrial machinery. These coatings provide resistance to corrosion, abrasion, moisture, and chemical agents. However, the performance and longevity of a polyurethane coating depend largely on the stability and homogeneity of its pigment dispersion. Achieving this can be particularly challenging in high-solid formulations, where pigment load is high and viscosity control is critical.
To address these challenges, UBE has developed the UBEDISP® range of hyperdispersants. These advanced additives are built on a polymeric anchoring structure, functionalized with stabilizing chains designed to match the polarity of the formulation system. This tailored design ensures excellent interaction with pigment surfaces, leading to stable, uniform dispersions that resist re-agglomeration and sedimentation, even under storage or thermal stress.
UBEDISP® grades are compatible with both solvent-based and polymeric systems, making them highly versatile across different polyurethane applications. In tests with UBEDISP® in organic solvents, coatings exhibited improved hydrophobicity, higher contact angles, better surface appearance, and increased resistance to environmental factors. These benefits translate into coatings that last longer, perform better, and require less maintenance over time.
Moreover, UBEDISP® hyperdispersants support better processability by helping maintain optimal viscosity, reducing formulation complexity, making its application easier and improving film formation. By incorporating UBEDISP® into their formulations, manufacturers can meet the growing demand for durable, high-performance polyurethane coatings in sectors where failure is not an option.To learn more about how UBEDISP® can transform your coatings, fill out the form and download the full technical document.
