Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Methyl 2-Methylpropenoate And 2-Sulfoethyl 2-Methyl-2-Propenoate is a specialized, sulfonated acrylic copolymer designed to deliver superior performance as a dispersant and rheology modifier. This product matters for its ability to provide exceptional stability and flow control in complex aqueous systems, preventing agglomeration and settling. Industrial manufacturers in sectors such as coatings, adhesives, construction chemicals, and textile processing require this polymer to enhance the quality and consistency of their final formulations.

Application

• Pigment and Filler Dispersant in water-based paints, inks, and coatings to achieve uniform color and gloss.
• Rheology Modifier in construction materials like cementitious renders and tile adhesives to improve workability and sag resistance.
• Stabilizing Agent in ceramic slurries and advanced material suspensions to prevent particle sedimentation.
• Textile Processing Aid for dye leveling and as an anti-precipitant in dye baths.
• Scale Inhibitor and Dispersant in industrial water treatment formulations.
• Grinding Aid in the production of mineral and pigment pastes to increase milling efficiency.

Quality Control

Our production of this sulfonated acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like dispersancy and viscosity. Each lot is tested against internal specifications for solids content, pH, viscosity, and sulfonate group concentration. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your formulation requirements.

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/59-77°F). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture uptake, which can affect product performance.
