Overcoat Protective Paste

This overcoat protective paste is used to provide an additional protective layer over electronic components, ensuring enhanced insulation and shielding against environmental factors such as dust, moisture, and mechanical stress. It is commonly applied in high-voltage circuits and sensitive electronic assemblies.

It adheres to substrates like metals,  ceramics, etc. Key properties include adjustable viscosity, thermal conductivity (for heat dissipation), low shrinkage, and resistance to thermal degradation.

High Temperature Firing Overcoat Paste

OP850 series is an environmental friendly high temperature overglaze paste designed as overlay or interbedded insulation. It has good compatibility with various ceramic substrates and applied to hybrid circuit, resistor plate, heating element, and sensitivity element.
