ISONEL*885 **ST CURING INSULATING V ARNISH
DESCRIPTION:
ISONEL*885 **ST CURING INSULATNG V ARNISH is a fast curing,modified polyester varnish designed for use in systems containing PVC lead wires or other temperature sensitive may also be used as a general purpose insulating varnish in applicati*** where irs significantly lower cure
temperature o* **ster curing cycle would be en advantage. Designed for conventional dip and bake applicati***. ISONELR885 cures to a clear,tough,seni-rigid film for use in Class A(105℃) through Class H (180℃)systems.
RECOMMENDED USES:
ISONELR885 is recommended for use on transformers,stators and rotating parts,especially those with temperature sensitive components.

Isonel 885 Fast Curing Insulating Varnish
SHELF LIFE INFOMWATION
Isonel 885 has a shelf life of twelve months when stored at 25℃ or is unaffected by freezing temperatures.Varnish stored for longer than 12 months of exposure to temperatures over 25℃ for long
periods of time may incrase in viscosity. If this occurs,additional thinner (xy*** or mineral spirits)may be added to reduce the varnish and make it usable.Varnish so treated may not meet original solids/viscosity specificati***. This product can be stored in unlined containers for storage up to twelve months.
Longer storage in the presence of sreel may cause discoloration of the varmish.
