Good Insulation Overglaze Non Conductive Paste for 430 Type
Stainless Steel Heaters
FG850X series is an environmental friendly high temperature
overglaze non conductive paste designed as overlay or interbedded
insulation. It is non-toxic element up to European RoHS
environmental regulation (2002/95/EC), and has good compatibility
with various ceramic substrates.
Also, if a protective insulation is required for the heating
element, the same dielectric paste that has been used to insulate
the steel also could be chosen.
The overglaze non conductive paste FG850X series could be screen
printed on ceramics and stainless steel substrates for applications
such as resistor networks, resistor plate, heating element,
sensitivity element for protective insulation purposes.
It is dried at 125℃ and fired using a one hour 850℃ profile in a
belt furnace with 15 minutes at peak temperature.

1. Excellent insulating resistance
The overglaze insulating paste FG850X series is with excellent
insulating resistance. The high breakdown voltage could be up to
2000 VAC/min (fired thickness >80μm, 25℃).
2. Strong adhesion
The overglaze insulating paste FG850X series is with strong
adhesion. Place the heating plate on a round tube of 40mm diameter,
and bend it at 90 degrees with uniform force, no crack on the
dielectric layer of the stainless steel plate.
3. Excellent printing characteristics
The paste is with proper viscosity, good thixotropy and levelling
properties which enables excellent printing properties. After
screen printing, the film is well-distributed, compact, clear and
4. Smooth and fine surface
The fired dielectric surface is with uniform color, and flatness
5. Excellent thermal conductivity and heat resistance properties.
6. Good Compatibility
The overglaze paste is with good compatibility with resistor paste,
dielectric paste and conductor paste. After fired, there is no
bubbles, no obvious yellowing, and with smooth and dense surface.
The resistance re-fired drift is within 5%.
