Conductive Pastes PP for Manufacturing Resistors and Hybrid Circuits

PP series pastes are designed for manufacturing contacts of resistive elements of variable tuning resistors, sets of permanent resistors, hybrid microcircuits, chip resistors using corundum ceramics with aluminium oxide content not less than 94%. Paste is a homogeneous viscous mass of dark grey colour without foreign inclusions. The strength of adhesion to the surface of the base, kg/sq.cm, is not less than 60 for pastes PP-1, PP-3, PP-3OP. For other pastes of the series: PP-2, PP-4 and PP-5 this parameter is not normalised.
