Features Of Dow CAT 20000PA CMC PEO HPMC Thickener

  1. Multi-polymer synergistic thickening system combining carboxymethyl cellulose (CMC), polyethylene oxide (PEO), and hydroxypropyl methylcellulose (HPMC) for broad-rheology control.

  2. Excellent water solubility and rapid dispersion without lumping, enabling efficient cold-water hydration.

  3. Enhanced suspension stability and anti-sag performance in high-solids formulations under static and dynamic conditions.

  4. pH-stable viscosity profile across pH 3–11, minimizing sensitivity to formulation acid/base shifts.

  5. Low-foaming characteristic suitable for high-shear industrial mixing and spray-application systems.

Typical Applications Of Dow CAT 20000PA CMC PEO HPMC Thickener

  1. Architectural coatings: interior/exterior latex paints and primers requiring balanced open time and sag resistance.

  2. Construction mortars: tile adhesives, self-leveling underlayments, and cement-based renders.

  3. Agrochemical suspensions: SC (suspension concentrate) and SE (suspo-emulsion) formulations.

  4. Home care liquids: heavy-duty cleaners, gel-based disinfectants, and hard-surface degreasers.

  5. Industrial maintenance coatings: waterborne maintenance enamels and protective barrier coatings.
