PARFIX® 3420 is a very low viscosity, wicking-grade ethyl cyanoacrylate adhesive engineered for ultra-fast bonding in precision and industrial applications. Manufactured by Parson Adhesives under the Parfix line, this super-thin adhesive is designed to penetrate tight gaps and pre-assembled components where thicker CA glues cannot flow. With an extremely fast cure speed and excellent adhesion to a wide variety of substrates, PARFIX 3420 is ideal for repairs, reinforcement, and post-assembly bonding. Available in 1oz, 2oz, and 1lb bottles, it supports everything from bench-top precision work to high-volume industrial use.

What Is PARFIX® 3420?

PARFIX® 3420 is a very low viscosity ethyl cyanoacrylate (CA) adhesive formulated for capillary action and rapid fixture. With a viscosity of just 2–5 cps, it readily wicks into hairline cracks, tight joints, and porous surfaces, curing quickly upon contact with ambient moisture. This makes it especially effective for reinforcing assembled parts, bonding fine components, and stabilizing materials without disassembly.
