Description

Cyanoacrylic Acid Methyl Ester is a highly reactive monomer and a key intermediate in organic synthesis. This compound is valued for its ability to rapidly polymerize, forming strong, clear bonds, which is critical for high-performance industrial applications. It is essential for manufacturers in the adhesives, specialty polymers, and fine chemical synthesis sectors seeking reliable, high-purity raw materials.

Application

• Instant Adhesive Formulation: Primary monomer for the production of cyanoacrylate-based "super glues" and rapid-bonding adhesives.
• Specialty Polymer Synthesis: Key intermediate for manufacturing acrylic resins, impact modifiers, and other advanced polymeric materials.
• Medical Device Assembly: Used in formulating medical-grade cyanoacrylate adhesives for wound closure and device bonding.
• Electronics & Micro-optics: Employed in precision bonding applications for delicate electronic components and optical elements.
• Automotive & Industrial Repair: Base component for high-strength, fast-curing repair compounds and thread-locking fluids.
• Chemical Intermediate: Serves as a versatile building block in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals.

Quality Control

Our Cyanoacrylic Acid Methyl Ester is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, purity profiling, and stability checks. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize polymerization and maintain stability. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and open flame.
