Description

Hexyl 2-Cyanoacrylate is a high-purity, fast-curing monomer belonging to the cyanoacrylate ester family. This compound is valued for its strong, rapid adhesive properties and excellent bonding performance on a variety of substrates, including plastics, metals, and rubbers. It is an essential raw material for manufacturers in the medical device, electronics assembly, and specialty adhesive industries seeking reliable, high-performance bonding solutions.

Application

• Medical Device Assembly: Used in the precise bonding of components for disposable medical tools, catheters, and diagnostic equipment.
• Electronics Manufacturing: Ideal for securing small components, potting, and strain relief in circuit boards and sensors.
• Specialty Industrial Adhesives: Serves as a key ingredient in formulating instant adhesives (super glues) for industrial and consumer use.
• Automotive Part Bonding: Applied for bonding trim, gaskets, and lightweight composite materials where fast fixture time is critical.
• Optical Instrumentation: Used in the assembly of lenses and prisms due to its clarity and strong bond strength.
• Rubber & Plastic Repair: Effective for on-site repairs and prototyping of elastomeric and plastic components.

Quality Control

Our Hexyl 2-Cyanoacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC/HPLC, moisture content (Karl Fischer), and viscosity measurement, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are available upon request.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent polymerization due to atmospheric moisture.
