PARFIX® 3420 Very Low Viscosity Ethyl Super Glue – 1oz, 2oz & 1lb Bottles

PARFIX® 3420 is part of Parson Adhesives' industrial cyanoacrylate system for fast assembly and fabrication. PARFIX grades are selected by viscosity, substrate, gap and cure behavior, so the correct grade matters when bonding plastics, sign components and other close-fitting parts.

Choosing a PARFIX Grade

Low-viscosity grades flow readily into close-fitting joints, while higher-viscosity and surface-insensitive grades are selected for different gaps and substrate conditions. Do not choose solely by bottle size. Match the adhesive chemistry and viscosity to the materials and joint design.

Application Guidance

Use on clean, properly prepared compatible surfaces. Cyanoacrylates cure rapidly in thin bond lines; production parts should be test bonded before full assembly. PARFIX activators can be used where the manufacturer recommends faster cure or improved gap-filling behavior. Follow the current technical data and safety documentation for the exact grade.

Frequently Asked Questions

Is PARFIX the same as ordinary household super glue?
PARFIX is an industrial cyanoacrylate family with multiple grades engineered around specific viscosity, substrate and cure requirements.

Does more adhesive make a stronger CA joint?
Not automatically. Cyanoacrylates generally perform best in appropriately fitted joints; excessive gaps or incompatible surfaces can reduce performance.
