Lubrizol introduces new aqueous polymeric dispersant

Cleveland, OH – Lubrizol announces the introduction of Solsperse™ W90C, a high efficiency aqueous polymeric dispersant engineered to enhance pigment dispersion, stability and color development in a wide range of water-based coatings and inks.

Solsperse™ W90C is a 35% active, water-based dispersant designed to deliver rapid pigment wetting, strong viscosity reduction and reliable dispersion performance in both resin‑free and resin‑containing systems. This efficiency supports improved coloristic properties across diverse pigment types, ensuring consistent quality in demanding formulations, including water‑based inks used in flexographic, gravure and inkjet printing.

Key Performance Benefits of Solsperse™ W90C include:
Fast wetting for improved processing efficiency
Enhanced coloristic properties for stronger, cleaner shades
Wide pigment and resin compatibility to support formulation flexibility and complexity reduction
Improved dispersion stability supporting long term performance in aqueous systems
Strong performance in resin-free and especially strong performance in resin-containing grinds to maximize formulation flexibility
Suitable for multiple water-based applications, including analog and digital printing inks, architectural and industrial coatings
Strength Backed by Solsperse™ Hyperdispersant Technology
The introduction of Solsperse™ W90C further strengthens Lubrizol’s leadership in dispersant innovation. Solsperse™ Hyperdispersants are widely recognized for delivering outstanding performance in ink and coating formulations.

“Solsperse™ W90C represents an important advancement for coating and ink formulators looking to enhance pigment efficiency and formulation robustness,” said Dr. Alison Drasdo, Marketing Manager at Lubrizol. “Its fast-wetting capability and stability, particularly in resin-containing systems, gives formulators greater control, improved processing efficiency and the ability to achieve higher performing water-based coatings and inks.”

With its combination of stability, fast wetting and improved color development, Solsperse™ W90C provides a powerful tool for formulators seeking to meet the increasing performance demands of modern aqueous systems. Its compatibility across diverse formulations reinforces Lubrizol’s commitment to enabling high quality, efficient, and sustainable coating technologies that meet global market needs.
