Description

3-Methoxybutylcyanoacrylate is a specialized cyanoacrylate ester monomer known for its rapid polymerization and strong adhesive properties. This compound is particularly valued for its tailored reactivity and bond strength, making it a critical component in advanced industrial formulations. It is essential for manufacturers in the medical device, electronics, and specialty adhesive sectors seeking high-performance, fast-curing solutions.

Application

• Medical Device Assembly: Used as a key component in specialized tissue adhesives and for bonding medical-grade plastics and rubber.
• Electronics Manufacturing: Employed in potting compounds and for securing delicate micro-components where fast curing and low outgassing are required.
• Industrial Adhesives: Serves as a primary monomer in the formulation of high-strength, instant-bonding cyanoacrylate ("super glue") adhesives for metals, plastics, and ceramics.
• Automotive Repair: Utilized in quick-set adhesives for on-site repairs of interior trim, rubber seals, and certain plastic components.
• Optical Instrumentation: Applied in the assembly of lenses and prisms where clear, durable bonds are necessary.
• Consumer Product Assembly: Found in the manufacture of sports equipment, jewelry, and crafts requiring a strong, transparent bond.

Quality Control

Our 3-Methoxybutylcyanoacrylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, purity, and stability checks, to ensure it meets precise specifications for industrial and specialized applications. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize shelf life and maintain monomer stability. This product is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent polymerization from atmospheric moisture.
