Description

Decyl 2-Cyanoacrylate is a long-chain alkyl cyanoacrylate monomer, a specialized adhesive precursor known for its unique balance of flexibility and high-strength bonding. This compound matters for industrial applications requiring durable, moisture-curing adhesives with enhanced resistance to thermal and mechanical stress compared to shorter-chain homologs. It is primarily needed by manufacturers in the electronics, automotive, and medical device assembly sectors for potting, sealing, and precision bonding of dissimilar materials.

Application

• Electronics Potting and Encapsulation: Used to protect sensitive electronic components from moisture, vibration, and environmental contaminants.
• Medical Device Assembly: Employed in the manufacture of certain medical tools and disposable devices where a flexible, biocompatible (once cured) adhesive is required.
• Automotive Component Bonding: Ideal for bonding gaskets, trim, and sensors where tolerance to temperature fluctuations and oils is necessary.
• Optical Instrument Manufacturing: Used in the assembly of lenses and prisms due to its clarity and refractive index properties upon curing.
• Industrial Repair & Maintenance: Serves as a high-performance, instant adhesive for on-site repairs of machinery, rubber parts, and composites.
• Specialty Adhesive Formulation: A key raw material for formulators developing advanced cyanoacrylate adhesives with tailored viscosity, set time, and bond strength.

Quality Control

Our Decyl 2-Cyanoacrylate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by HPLC and impurity profile analysis, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all relevant specifications 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) and light-sensitive; exposure to atmospheric moisture or prolonged light will initiate polymerization and degrade the product.
