Description

Acrylic Acid-Hydroxypropyl Acrylate Copolymer is a versatile, water-soluble synthetic polymer designed for superior performance in aqueous systems. This copolymer is engineered to deliver excellent thickening, dispersing, and film-forming properties, making it a critical component in formulations requiring controlled rheology and stability. It is essential for manufacturers in the personal care, coatings, adhesives, and textile industries seeking to enhance product performance and process efficiency.

Application

• Personal Care & Cosmetics: Primary thickener and stabilizer in shampoos, shower gels, lotions, and creams, providing rich texture and suspension of actives.
• Paints & Coatings: Key rheology modifier in water-based architectural and industrial coatings to control application properties, improve leveling, and prevent sagging.
• Adhesives & Sealants: Used as a tackifier and rheology control agent in water-based adhesive formulations to enhance bond strength and application characteristics.
• Textile Processing: Serves as a thickener in pigment printing pastes and as a finishing agent to improve fabric hand feel and durability.
• Industrial & Institutional Cleaners: Acts as a soil suspension agent and viscosity builder in liquid detergents and cleaning solutions.
• Paper Coatings: Utilized as a retention aid and coating binder to improve paper smoothness, printability, and strength.

Quality Control

Our Acrylic Acid-Hydroxypropyl Acrylate Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent viscosity, pH, solid content, and residual monomer levels. Certificates of Analysis (COA) documenting full specifications are available for every shipment. Our production adheres to ISO 9001 standards, and the product is compliant with global regulations including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Keep away from incompatible materials such as strong oxidizing agents.
