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 components.It may also be used as a general purpose insulating varnish in applications where irs significantly lower cure
temperature o* **ster curing cycle would be en advantage. Designed for conventional dip and bake applications. ISONELR885 cures to a clear,tough,seni-rigid film for use in Cl* A(105℃) through Cl* H (180℃)systems.
RECOMMENDED US*:
ISONELR885 is recommended for use on transformers,stators and rotating parts,especially those with temperature sensitive components.
PHYSICAL PROPERTI*
viscosity@77℉zahn#2(seconds) 110-150
Centipoises 200-400
Specific Gravity 0.930-0.960
Solids Content, %48-52
Flash Point(ASTM D56-70, ℉/℃) 81/29
Viscosity Reducer BS-107
CURE CYCLE ISONELR885 cures in one (1)to four(4)hours at 250-300℉(121-149℃),the actual cycle depending on oven efficiency and the weight and shape of the treated unit.
