High Temperature Black Insulation Paste , Overglaze Ceramic Thermal Paste

Black Color Good Insulation Overglaze Thick Film Paste for Stainless Steel and Ceramic


FG8503 series is a black color environmental friendly high temperature overglaze 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 paste FG850X series including FG8503 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.

Feature Advantage

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. Low thermal expansion coefficient, small distortion

The thermal expansion coefficient of the overglaze insulating paste FG850X series matches perfectly with the stainless steel plate.

3. 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.

4. Smooth and fine surface

The fired dielectric surface is with uniform color, and flatness and smooth.

5. Good process stability

The overglaze dielectric paste FG850X series is fired at 850℃, and can endure several times of printing, drying and firing process without change.

6. Environmental friendly, up to RoHS regulation

This overglaze dielectric paste contains no toxic materials and heavy metal ions such as lead, Cadmium, nickel, and it is environmental friendly and meet environmental standard of RoHS regulation.

7. Perfectly match with the resistor paste, dielectric paste and conductor paste

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%.
