Poly(acrylic acid), 25% soln. in water [Mw ~345,000]

Poly(acrylic acid) (PAA) is a high-molecular-weight polymer known for its strong hydrophilicity, high viscosity, and excellent dispersing properties. It is commonly used in water treatment, coatings, and personal care formulations requiring controlled rheology and binding capabilities.

Applications:

Water Treatment: Used as a dispersant and scale inhibitor in industrial water systems.

Superabsorbent Polymers: Forms highly absorbent hydrogels in diapers, hygiene products, and medical dressings.

Coatings & Adhesives: Enhances adhesion, film formation, and stability in paints, inks, and pressure-sensitive adhesives.

Cosmetics & Personal Care: Functions as a thickener and stabilizer in gels, lotions, and skincare formulations.
