Hernon primers & surface preparation agents

Hernon
primers and surface preparation agents
for anaerobic adhesives

Hernon Primers are surface preparation agents for all Hernon anaerobic adhesives and sealants. Primers are optimized for each family of anaerobic products: Nuts N' Bolts, Cylinlok, Dripstop, Gasket Replacer, HASA, and Ultrabond UV cure systems. Please refer to the appropriate catalog section or technical data sheet (TDS) for specific recommendations.

Primers provide the necessary chemistry to initiate polymer formation at the part surface. This action is initiated by catalysts contained in the formulation. The solvent in the primer formulation evaporates leaving a thin film of the catalyst.

INACTIVE SURFACES:

Primers provide the anaerobic adhesives the needed ions to cure with predictability on "inactive" or "Passive" surfaces: -Aluminum -Anodic Coatings - Cadmium -Ceramics - Gold - High Alloy Steels - Passivation Coatings -Plated Surfaces - Silver - Stainless Steel -Thermoset Plastics -Titanium - Zinc

Temperature has a direct effect on the cure rate of anaerobic adhesives. Higher temperatures promote faster cure times. Primers restore predictability to adhesive cures when temperatures are less than normal room temperature levels, 70*F. Without priming, cures in very cold temperatures extend into days, not hours.

Each Primer formulation offers additional processing flexibilities with its "on-part life." Depending on theprimer, you can prime parts a week or more ahead of time, before assembly. Long on-part life allows batch treating of sub-assemblies ahead of time. Baskets of parts can be dunked or bond areas preprimed to speed assembly with less assembly line integration needed.

To apply primers - spray, dip, brush, dispense, or drip on part. Allow solvent (if present) to flash-off (evaporate) fully. Apply adhesive to mating surface and assemble parts.
