Overview
Potassium methacrylate is a potassium salt of methacrylic acid, widely used in polymer chemistry. It serves as a reactive monomer in the production of various polymers and copolymers. Due to its ability to form clear and durable materials, it is favored in industrial applications requiring high-performance plastics. This compound is typically supplied as a white crystalline powder, soluble in water, making it versatile for formulations in aqueous systems. Its reactivity allows for copolymerization with other monomers, enhancing material properties such as adhesion, flexibility, and chemical resistance.
Physical and Chemical Properties
Potassium methacrylate exhibits solubility in water, which is advantageous for aqueous polymerization processes. Its molecular weight is approximately 124.18 g/mol, and it polymerizes readily under appropriate conditions, forming transparent and durable polymers. The compound is stable under recommended storage conditions but may degrade if exposed to moisture or high temperatures. Its reactive nature requires careful handling to prevent premature polymerization, often necessitating inhibitors during storage and transportation.
Main Applications
Potassium methacrylate is primarily used in the production of specialty polymers and copolymers. It is a key ingredient in adhesives, coatings, and dental materials, where clarity and durability are essential. In industrial settings, it is employed to manufacture impact-resistant plastics and elastomers. Its ability to enhance material properties makes it valuable in automotive, construction, and medical applications. Additionally, it is used in research and development for creating novel polymer formulations.
Safety and Storage
Handling potassium methacrylate requires adherence to safety protocols to minimize exposure. Protective gloves, goggles, and respiratory equipment are recommended to prevent skin contact, eye irritation, and inhalation of dust. Storage should be in a cool, dry place, away from moisture and direct sunlight. The compound should be kept in tightly sealed containers to prevent degradation. In case of spillage, absorb with inert material and dispose of according to local regulations.
B2B Procurement Guide
When procuring potassium methacrylate, verify the supplier's credentials and request documentation such as MSDS and CoA. Purity levels and batch consistency are critical for industrial applications. Consider purchasing from manufacturers with a proven track record in chemical supply. Bulk orders may attract discounts, but ensure storage facilities meet safety standards. For reference, prices range approximately $20-$50 per kilogram, depending on quantity and purity.
