Description

2-Propenoic acid, 2-methyl-, telomer with butyl 2-propenoate, tert-dodecanethiol, ethenylbenzene, 2-hydroxyethyl 2-propenoate and 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonic acid, compd. with 1,1'-iminobis[2-propanol] is a specialized, high-performance polymeric dispersant and rheology modifier designed for demanding aqueous systems. This advanced copolymer compound is engineered to provide exceptional stabilization and viscosity control for pigments and fillers. It is a critical raw material for formulators in the coatings, inks, and construction chemicals industries seeking to enhance product performance and process stability.

Application

• Aqueous Industrial Coatings: Acts as a primary dispersant and grinding aid for organic and inorganic pigments, improving color strength, gloss, and long-term stability.
• Architectural Paints: Provides superior pigment wetting and stabilization in interior and exterior emulsion paints, preventing flocculation and settling.
• Printing Inks: Used in water-based flexographic and gravure inks to ensure consistent rheology, sharp print quality, and reduced foaming.
• Construction Chemicals: Enhances the workability and water retention of tile adhesives, grouts, and self-leveling compounds by effectively dispersing cement and other mineral fillers.
• Pigment Concentrates and Masterbatches: Serves as a key component in the production of high-solid, low-viscosity pigment preparations for universal tinting systems.
• Paper Coatings: Improifies the dispersion of clay and calcium carbonate, leading to smoother coatings with better optical properties.

Quality Control

Every batch of our polymeric dispersant is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure consistent performance. Key parameters such as solid content, viscosity, pH, and acid value are rigorously controlled. Certificates of Analysis (COA) documenting batch-specific data are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Protect from freezing and extreme heat. Under these conditions, the product has a typical shelf life of 24 months from the date of manufacture.
