Laser EX 50 is a peroxide -based chemical polishing product that will provide a high luster on brass and most copper alloys. In many cases the Laser EX 50 will give a chemical alternative to buffing. Parts processed in the laser system can subsequently be plated, oxidized, soldered, or lacquered. The high luster produced by Laser EX 50 is superior to that obtained in the conventional chromic or nitric acid based bright -dips. It is not a direct replacement for these solutions, longer immersion times and extra process tanks are required for optimum results of the Laser EX 50 process.
