2-Diazo-1-naphthol-4-sulphonic Acid Sodium Salt (CAS 64173-96-2)
The core water-soluble DNQ salt — a main component for DNQ-based coating solutions used to manufacture UV CtCP offset printing plates and electronic photoresists. It is converted into its sulphonyl chloride for further processing.
Built for consistent qualification into your process.
Where Orion Freedom 2-1-4 is used.
UV CtCP offset printing plates
Used as the primary DNQ active in coating solutions for computer-to-conventional-plate systems imaged at 360–375 nm. UV CtCP offset printing applications.
Electronic photoresists
Supplied as a diazonaphthoquinone active for positive photoresist formulations where resolution and clean development matter. DNQ one-pack ester for photoresists.
