Positive Photomask Cleaners

PPC 1-1, PPC 593 and CA-40

Transene Positive Photomask Cleaners are aqueous, water miscible cleaners for critical photomask cleaning applications. PPC 1-1 Positive Photomask Cleaner may be used on a variety of delicate mask substrates including iron oxide, chrome, or emulsion without damaging the surface. PPC 593 is a high pH (> 12) cleaner containing non-PFOS surfactant and suitable for glass, quartz, and other substrates. CA-40 is the traditional Cyantek formulation with room temperature operation.
