Laserguard HFP is a chrome-free, liquid product that is added to a water rinse to prevent tarnishing, staining, green salt formation, pit corrosion, finger marking and spotting-out of copper surfaces. It is used in conjunction with the laser pickling system in copper and brass milling applications.
Laserguard HFP is ideally suited for application in the final water rinse (still) following the copper plating or pickling process because it will preserve the fresh appearance for weeks, even under high humidity storage conditions.
Laserguard HFP solutions may be used to protect copper, brass or their alloys.
The barrier film produced by this solution is completely invisible and has many times the corrosion resistance of bare copper. It will withstand 200 hours exposure to tropical humidity conditions without discoloration, whereas bare copper will start to corrode after one hour.
Note: Laserguard HFP is not recommended for protecting copper surfaces against outdoor exposure. It should only be used on work that is stored indoors.
