ISONEL 885 Solvent Impregnating Varnish Electrical Insulation System Dip & Bake
Product Description
ISONEL 885 is a fast curing, modified polyester
varnish designed for use in systems containing
PVC lead wires or other temperature sensitive
components. It may also be used as a general
purpose insulating varnish in applications
where its significantly lower cure temperature or
faster curing cycle would be en advantage.
Designed for conventional dip and bake
applications. ISONEL 885 cures to a clear,
tough, semi-rigid film for use in Class A (105°C)
through Class H (180°C) systems.
Areas of Application
ISONEL 885 is recommended for use on
transformers, stators and rotating parts,
especially those with temperature sensitive
components.
Approvals
ISONEL 885 have got UL recognition, its UL
OBOR file number is E314793.
Processing
ISONEL 885’s cure cycle is recommended
as below:
230-300°F (110-149°C), cure for 1-4 hours
The actual cycle depending on oven efficiency
and the weight and shape of the treated unit.
MAINTENANCE
ISONEL® 885 exhibits excellent storage
stability. Its viscosity may increase as solvent
evaporates from the dip tank. X2 is the thinner
of ISONEL 885. Viscosity may be reduced or
maintained by the addition of X2.
Packaging
ISONEL 885 is currently sold in 15kg & 180kg
containers for ease of use.
Health & Safety

Sheet (MSDS) for ISONEL 885.
Shelf life
Isonel 885 has a shelf life of twelve months
when stored at 25ºC or below.
It is unaffected by freezing temperatures.
Varnish stored for longer than 12 months of
exposure to temperatures over 25ºC for long
periods of time may increase in viscosity. If this
occurs, additional thinner (X2 or mineral spirits)
may be added to reduce the varnish and make
it usable. Varnish so treated may not meet
original solids/viscosity specifications.
This product can be stored in unlined steel
containers for storage up to twelve months.
