Electroloc®

Overview

Electroloc is a pre-applied process in which low halogen micro-encapsulated epoxy based adhesives are coated onto customer fasteners in bulk. Once applied to either internal or external threads, Electroloc remains inert on the fastener until assembly. Electroloc has a halogen content of of less than 500ppm making it a great choice for fasteners in electronic components.

How it Works

After choosing Electroloc processing, have your parts sent to one of ND’s service centers. ND will then apply a microencapsulated epoxy resin suspended in a hardener to fasteners. After drying, parts are shipped back to the customer ready for use. When installed, the forces of engagement crush the microscopic capsules of epoxy resin, mix the separate reactant components, and initiate a chemical reaction which locks the parts together.

Features

Versatile

Electroloc processing is compatible with most fastener sizes, configurations, materials and finishes.

Exceptional Locking

Extensive testing indicates that Electroloc processed fasteners provide two to four times greater breakaway torque than conventional ``plastic`` thread locking devices.

Resists Chemicals

Processed parts resist and seal against most automotive fluids. Oil, water, antifreeze, and gasoline have virtually no effect on performance once the final cure has been achieved.

Low Prevailing On Torque

Compared to patch threadlockers, Electroloc fasteners have a lower on torque and assemble easily with common hand tools.

Long Shelf Life

Materials used for Electroloc processing have an on part life of 2 years and will remain inert until a cure is activated by thread engagement.

Surpasses IFI Standards

Electroloc processed parts meet or exceed all torque requirements of IFI 125, IFI 525, as well as automotive adhesive coated fastener performance specifications.

Benefits

Saves Time: Processed fasteners can be automatically fed through standard feeding devices – speeding up your workflow and improving productivity.
Saves Money: Electroloc processing is less expensive than hand applying bottled thread locking compounds at the point of assembly. It also eliminates the need for costly lock washers, cotter pins or castellated nuts.
Quality Control: Pre-Applied Electroloc fasteners are coated to specification, ensuring consistent performance, unlike the variation from hand applying bottled products.
Reliability: Under most operating conditions, processed parts are unaffected by vibration or reversal of stress and greatly reduces the need to re-tighten fasteners.

Notes

Under typical conditions, have a fixture time of 4 hours with a full cure in 72 hours.
It is recommended that Electroloc processed parts are not reused.
Typically the first one to three threads from the end of the fasteners are left free of material to assure ease of starting.
Shelf life of un-activated part is 2 years when stored in a dry, cool environment.

Please note that breakaway torque data is from test results conducted on an M-4 x 0.7 zinc finish bolts and M-4 x 0.7 zinc nuts. Performance may vary depending on fastener finish.
