Description

Potassium Methacrylate is the potassium salt of methacrylic acid, a versatile monomer essential for creating high-performance polymers. This compound is valued for its ability to impart water solubility, ionic character, and enhanced adhesion properties to copolymer systems. It is a critical raw material for industries requiring specialized acrylic resins, superabsorbent polymers, and advanced coating formulations. Potassium Methacrylate CAS NO 6900-35-2 is engineered to meet the stringent quality demands of global chemical manufacturing.

Application

• Superabsorbent Polymers (SAPs): A key monomer in the production of SAPs used in hygiene products like diapers and adult incontinence pads.
• Water-Soluble Acrylic Resins: Serves as a functional comonomer to introduce water solubility and dispersibility in coatings, adhesives, and textile finishes.
• Dispersants & Scale Inhibitors: Used in the synthesis of copolymers for industrial water treatment applications to control scale and disperse particulates.
• Adhesive & Sealant Formulations: Enhances adhesive strength and compatibility in pressure-sensitive adhesives and construction sealants.
• Photoresist & Electronic Chemicals: Employed in the manufacture of light-sensitive resins for photolithography in semiconductor and PCB production.
• Cross-linking Agent: Functions as an ionic cross-linker to improve the mechanical strength and thermal stability of hydrogel networks.
• Personal Care Products: Used in the synthesis of polymers for hair styling gels, creams, and other cosmetic formulations requiring film-forming properties.
• Medical & Biomedical Hydrogels: A component in creating hydrogels for drug delivery systems, wound dressings, and contact lenses.

Quality Control

Our Potassium Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profile analysis, and physical property verification, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters is provided with every shipment to guarantee traceability and compliance.

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) and must be kept under an inert atmosphere or in sealed, moisture-proof packaging to prevent caking and polymerization. Keep away from heat, sparks, and incompatible materials such as strong oxidizing agents.
