Dow CAT 20000PA CMC PEO HPMC Thickener

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.

Dow CAT 20000PA CMC PEO HPMC Thickener – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Dow CAT 20000PA in formulations?

A: Dow CAT 20000PA is a multi-polymer thickening system designed to provide synergistic rheology control—enhancing viscosity, improving suspension stability, and delivering non-drip or shear-thinning behavior in aqueous systems. It combines carboxymethyl cellulose (CMC), polyethylene oxide (PEO), and hydroxypropyl methylcellulose (HPMC) to achieve balanced performance across diverse application conditions.

Q2: Is Dow CAT 20000PA suitable for use in water-based coatings and architectural paints?

A: Yes—it is widely used in interior and exterior water-based architectural coatings to improve sag resistance, brush/roller drag, and pigment suspension. Its hybrid polymer structure helps maintain consistent viscosity during storage while supporting good film formation and leveling during application.

Q3: How does temperature affect the viscosity performance of this thickener?

A: The formulation exhibits good thermal stability across typical ambient and processing temperatures. Unlike some single-polymer thickeners, the combination of CMC, PEO, and HPMC provides more consistent viscosity retention upon moderate heating and cooling cycles, though prolonged exposure to elevated temperatures (>60°C) may gradually reduce thickening efficiency depending on pH and ionic strength.

Q4: Can Dow CAT 20000PA be used in personal care formulations such as shampoos or body washes?

A: Yes—its non-ionic and anionic components offer compatibility with common surfactant systems and mildness profiles suitable for rinse-off personal care products. It delivers rich, creamy rheology and stabilizes suspended actives or opacifiers without significantly interfering with foam structure when properly dispersed and hydrated.
