Abstract

A printing paste suitable for application by an elastically deformable stamp on a substrate and method for said application. The paste comprises a powdered solid component in an organic carrier with a weight ratio of between 6:4 and 8:2. The organic carrier comprises 4-9% by weight ethyl cellulose, 74-82% alpha-terpineol, and 8-17% benzyl alcohol. The paste may also contain up to 20% by weight of polyethylene glycol. The solid component of the paste is preferably a mixture of platinum and zirconium dioxide which can be applied as an electrically conductive paste to form a conductive coating on a substrate, preferably a tubular or other substrate having a non-planar surface. The paste has a viscosity of between 6 and 8.5 pascal seconds.
