3270R is a silver conductor paste designed for screenprint application of a fired conductive electrode. 3270R forms a highly adherent bond to many compositions including alumina. The paste has good rheological properties and long screen life. The film has good initial and aged adhesion and is readily solderable.
Key Features
Excellent solderability Good initial and aged adhesion Long working lifetime on the screen
