IP2109

Description

IP2109 is a lead free, screen printable, overglaze paste for different purposes, especially for protecting thick film resistors or conductors. Because of the high firing temperature it fires to a transparent green colour and very dense glaze layer which is highly passivated to withstand abrasion and aggressive media occurring in plating processes.

Key Features

Extremely resistant vs plating solutions eg. Ni baths with pH values of 4 – 5 and H2SO4 baths with pH values < 1. It is also resistant to alkaline solutions with pH value of ≤ 9 Excellent compatibility with different HERAEUS resistors and conductors on alumina and dielectrics
