VIKING V1380FC is a faster curing version of
V1380 low viscosity electrical insulating varnish.
It is a solvented, alkyd resin based, heat curing,
Class ‘180°C’ varnish (MW35 wire) with
excellent electrical properties, good tank
The following cure schedule is recommended
for conventional VPI:
Heat component to drive off moisture and
cure electrical tapes and other
thermosetting materials: 250°F (120°C) to
275° (135°C) is typical. excellent electrical properties, good tank
stability and anti-tracking qualities.
V1380FC cures to give a tough, bright surface
finish, excellent protection against leakage
currents and is particularly useful for protecting
metal surfaces against oxidation.
It is compatible with most wire enamels and
tapes used in transformers and motors.
Having the same resin and solvent base,
V1380 can also be supplied in a black version,
Viking V1380FC Black for applications where
resin visibility / aesthetic finishes are required.
Permit to cool to about 105°F (40°C).
Immerse partly cooled transformers in
vacuum tank containing varnish. Where
necessary “dry vacuum” may be used first
(see note 1 below).
Apply vacuum for 10 to 15 minutes, then
release vacuum.
Permit units to soak in V1380 for 15
minutes after release of the vacuum.
If needed for better impregnation, apply
pressure of 15 psi for 10 to 15 minutes after
soaking. Release pressure, then open
tank.
Drain excess varnish over the tank or over
The preferred applications for V1380FC series
are via conventional dip and bake / VPI and / or
trickle application for:
Stators
Transformers
Coils
Please note that this product is not
recommended for the impregnation of deep
section windings.
a drain board.
Place in preheated oven for the following
times at temperature (cure times listed
below are after units reach listed
temperature.
135°C/ 275°F 25 minutes
120°C/ 248°F 50 minutes
110°C/ 230°F 2 hours
100°C/ 212°F 3-4 hours
90°C/194°F 6-8 hours
1. For “dry vacuum” – place units in vacuum V1380FC is UL recognised in file number
E73071 and has the many associated
insulation systems. Please contact Elantas
Zhuhai Technical Service for more information.
Application methods are by conventional dip
and bake / VPI and / or trickle.
When using V1380FC based resins care should
be taken to ensure that the resin is not exposed
to components with surface temperatures in
excess of 40°C to minimise solvent loss and
that the resin stock does not exceed 25°C.
tank with no varnish. Vacuum at 29" to 30"
vacuum for 5 minutes. Break vacuum to
15" or 20" by admitting air. Admit varnish
through a control valve to vacuum tank.
Increase vacuum to desired level and hold
for 15 to 20 minutes, then release vacuum
and continue steps 5 to 8 above.
V1380FC is currently sold in 16.4 kg & 177kg
containers for ease of use.
Note must be made that the component
temperature will lag significantly behind
indicated oven air temperature, to a degree that
will depend on the machine size and oven
efficiency.
