Dow CAT 15000PA CMC PEO HPMC Thickener

Features Of Dow CAT 15000PA CMC PEO HPMC Thickener

1. Multi-polymer synergistic formulation combining carboxymethyl cellulose (CMC), polyethylene oxide (PEO), and hydroxypropyl methylcellulose (HPMC) for balanced rheology and enhanced suspension stability.

2. Excellent water solubility and rapid dispersion with minimal clumping, enabling efficient cold-water hydration in industrial mixing systems.

3. High shear-thinning behavior ideal for spray application, pumping, and high-shear processing without loss of viscosity recovery.

4. pH-stable performance across broad range (pH 3–11), maintaining thickening efficacy in acidic, neutral, and mildly alkaline formulations.

5. Non-ionic and low-ash composition ensures compatibility with electrolytes, surfactants, and biocides commonly used in industrial and household products.

Typical Applications Of Dow CAT 15000PA CMC PEO HPMC Thickener

1. Architectural coatings — provides sag resistance, brush/roll extension, and spatter control in interior and exterior latex paints.

2. Agrochemical suspensions — stabilizes solid active ingredients in SC (suspension concentrate) and SE (suspo-emulsion) formulations.

3. Industrial cleaning gels — delivers yield stress and structural integrity for vertical-surface cling and controlled release of actives.

4. Construction mortars and tile adhesives — improves water retention, workability, and open time without compromising bond strength.

5. Personal care gels and liquid soaps — imparts smooth texture, clarity, and mildness suitable for rinse-off and leave-on formulations.

Dow CAT 15000PA CMC PEO HPMC Thickener – Frequently Asked Questions (FAQ)

Q1: What is the primary functional role of Dow CAT 15000PA in formulations?

A: Dow CAT 15000PA is a multifunctional rheology modifier designed to provide viscosity enhancement, suspension stabilization, and improved texture in aqueous systems. Its hybrid composition—combining carboxymethyl cellulose (CMC), polyethylene oxide (PEO), and hydroxypropyl methylcellulose (HPMC)—enables synergistic thickening and enhanced shear-thinning behavior across diverse pH and ionic strength conditions.

Q2: Is Dow CAT 15000PA compatible with common surfactants and electrolytes found in industrial cleaners or personal care products?

A: Yes, it demonstrates broad compatibility with anionic, nonionic, and amphoteric surfactants, as well as moderate tolerance to common electrolytes such as sodium chloride and sodium carbonate. Performance stability may vary depending on concentration and system pH; pre-testing in the final formulation is recommended to optimize viscosity response and long-term storage behavior.

Q3: How does temperature affect the viscosity performance of Dow CAT 15000PA solutions?

A: Solutions exhibit typical thermothickening behavior up to approximately 60–70 °C due to enhanced polymer chain hydration and entanglement, followed by gradual viscosity decline at higher temperatures. Reversible viscosity recovery is generally observed upon cooling, supporting utility in processes involving mild thermal cycling.

Q4: What are typical dosage guidelines for achieving target viscosity in water-based systems?

A: It is typically used at low concentrations, generally ranging from 0.1% to 2% by weight in the final formulation, depending on desired viscosity, substrate interaction, and presence of other rheology modifiers. Optimal dosage should be determined empirically through small-scale trials, as performance is influenced by dissolution method, mixing energy, and co-formulant interactions.

Q5: Does Dow CAT 15000PA require special handling during dispersion or dissolution?

A: To avoid lumping and ensure efficient hydration, gradual addition under high-shear mixing into cold water is recommended. Pre-blending with inert carriers like sucrose or salt can further aid dispersion. Avoid direct addition to hot water or highly viscous media without adequate agitation.
