Glass Pastes
These Glass Pastes are highly heat-resistant protective coating materials designed for thick-film processes. They are highly compatible with our copper pastes and resistive pastes, providing stable adhesion and uniform film quality.
The formed glass protective film securely covers the electrode layer and the resistance layer, and prevents oxygen and moisture from entering, thereby suppressing oxidation degradation of the conductor and resistor for a long time.
Even in applications where resistive elements are exposed to temperatures of 300°C to 400°C, such as ceramic heaters, these materials deliver excellent reliability by minimizing cracking, delamination, and property changes.
Features

Low Residue Formation Under Nitrogen Atmospheres
A clean and uniform protective film can be formed with very little residue during firing and minimal soot even under a nitrogen atmosphere.
