Positiv 20 photosensitive lacquer is designed for use in the production of printed circuit boards (PCBs) and the creation of hliogravure images (a process by which a photograph is etched onto the surface of a copper plate to produce high-quality image prints). The photo-resist formula directly transfers the positive pattern of a circuit diagram onto working materials and is resistant to acidic etching fluids to produce high quality results. Features and Benefits Facilitates the manufacture of all circuit board formats Has a high degree of tolerance to acidic fluids to produce high resolution results Easily removed using solvents containing ester or ketone, or aqueous alkaline products Lacquer can be temperature treated at 190C to improve inscription durability Typical Applications Glass Acrylics Aluminium Copper Brass Steel Standards ISO 9001:2015
