Description

Methacrylammonium Hydrogen Sulphate is a specialized organic salt monomer of significant industrial importance. This compound serves as a key reactive intermediate in the synthesis of advanced polymers and functional materials. It is primarily utilized by manufacturers in the polymer, specialty chemical, and water treatment industries seeking to introduce cationic functionality or enhance adhesion properties in their formulations.

Application

• Cationic Polymer Synthesis: A crucial monomer for producing polymers with permanent positive charges, used in flocculants and retention aids for water and wastewater treatment.
• Paper Manufacturing: Used in the production of wet-strength resins and as a retention/drainage aid to improve paper quality and production efficiency.
• Enhanced Oil Recovery (EOR): Employed in the synthesis of polymers that modify the viscosity of injection water to improve oil displacement in reservoirs.
• Textile & Fiber Modification: Imparts cationic sites on fibers for improved dye uptake, antistatic properties, and soil release characteristics.
• Personal Care & Cosmetics: Used in the formulation of cationic conditioning polymers for hair care and skincare products.
• Adhesive & Coating Systems: Incorporated to improve adhesion to anionic surfaces, such as metals, glass, and certain plastics.

Quality Control

Our Methacrylammonium Hydrogen Sulphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are provided with every shipment to guarantee supply consistency and reliability for your critical processes.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
