How to apply

Make sure that all cable glands are tight, and apply the encapsulant being careful to cover all
electrical componets and avoiding air entrapment.
Start filling from a corner or through a hole so that the electrical printed circuit board and its
terminals are covered with gel from below, and the MJK cable and its wires are completely
entrapped in gel. The full amount of mixed gel should be used for correct MagFlux

protection.

For information on appropriate dispensing equipment for your application, please contact an
authorized MJK sales or service representative.

Curing

The junction box filled with MJK dielectric gel must be held horizontal for at least 5 hours at
approx. 25 degrees Celsius (75 degrees Fahrenheit). Expect full curing to be completed in
about 3 days depending on the ambient temperature.

Compatibility

In some cases MJK dielectric gel may fail to cure to optimum properties when in contact with
certain plastics or rubbers. Cleaning the substrate with solvent or baking slightly above the
cure temperature can eliminate the problem.
Certain chemicals, curing agents and plasticisers can inhibit cure. These include:
- Organo-tin compounds and silicone rubber containing organo-tin catalysts
- Sulphur, polysulphides, polysulphones and other sulphur containing materials
- Amines, amides and azides

Repairability

When cured in place, MJK dielectric gel can be removed with reletive ease, repairs or chang-
es made and protected with additional gel. Since this gel develops a good adhesion to itself,
the repaired region will become an integral part of the original material.
