Product Description
LINQBOND C401 is a single-component, low to medium viscosity ethyl cyanoacrylate adhesive formulated for rapid polymerization and high-strength bonding across different substrates, including fiberglass, wood, and leather. C401'S optimized rheological properties make it excellent for wicking and gap-filling applications for clearances up to 0.15 mm. LINQBOND C401 is ISO 10993-5 certified for biocompatibility.
Product Key Features
- Fast-curing — achieves fixture strength within seconds, minimizing clamping time and accelerating assembly processes.
- Low to medium viscosity — ideal for filling small gaps.
- Ambient temperature curing — does not require external heat source or curing equipment.
Applications
- Bonding of various components requiring biocompatible adhesive solutions.
- General industrial assembly
- Bonding of composite materials

Instructions for Use
- Ensure parts are clean, dry and free from contaminants such as oil and grease.
- Apply product to one side and hold parts until handling strength is achieved. Ensure there is adequate, even pressure between parts. A sufficient bond is formed in less than a minute and maximum strength is attained in 24 hours.
- Wipe off excess adhesive from the top of the container and recap. Avoid exposure to air as moisture may degrade the adhesive.
