Cupbradip

Chromate-free, liquid chemical polish for brightening

Copper, brass and bronze by immersion application

 

Cupbradip is a chromate-free, highly acidic liquid chemical polish, used for brightening old and tarnished copper, brass and bronze parts. It can be used to brighten all kinds of copper and copper-alloyed parts Including light fixtures, copper contact terminals, brass fittings and valves, meters, gauges, regulator parts and building hardware.

 

Cupbradip eliminates time-consuming, tiresome, manual polishing and buffing of intricately and irregularly shaped parts with “nooks and corners”. When the metal surfaces that have been thoroughly precleaned of all contaminants is immersed in the Cupbradip at room temperature, the acidic liquid polish chemically dissolves and removes oxides, stains, tarnish and discolorations, from copper or brass and its alloys and a clear, metallic brightness is restored. After thorough fresh water rinse, it leaves the bare-metal clean and shiny bright. Then, to give the surfaces long-term indoor protection from retarnishing, the metal parts are rinsed and then immediately dipped in Cupbradip-F.

 

Cupbradip-Finhibitor is a mildly alkaline liquid tarnish - preventing agent that is specially formulated to provide longterm protection. The special blend organic salts guards copper, brass and bronze parts against tarnishing, oxidation and corrosion after they have been chemically polished by Cupbradip.

 

 

Application procedure:

 

First remove all oil, grease, paint and lacquer from parts by precleaning them with a suitable alkaline cleaner such asThelnikal LD. If parts are covered with hard water scale, they should be descaled with a suitable descalant, such asKWIKSHOT, and thoroughly rinsed.

Once the contaminanats are removed, the parts are immersed in Cupbradip, as supplied, at room temperature. The durtion of dip depends on the amount of stain and tarnish to be removed and surface finish. Follow with thorough fresh water rinse.

 Then, to give parts long-term indoor protection from retarnishing, oxidation and corrosion, they should be immediately immersed in a solution of Cupbradip-F at 10% by volume for 30 seconds at room temperature. Follow with thorough water rinse and air dry.
