Kind of lacquer for masking parts for hard chrome


Q. Dear sirs:

I would appreciate if someone can indicate me what kind of lacquer I can use to mask parts before they are hard chrome plated. Also what kind of pigment I must add to it to give it a colour in order to visually inspect the application before the chrome process.

Thanks in advance.

A. Dear Oscar,

These masking lacquers are usually called "stop-off" lacquers. They are usually nitrocellulose based, and a little thicker than spraying viscosities. You can mill any pigment you want, most common I see are orange and green. If you don't want any color, you can add an ultra-violet pigment, and inspect the coating under a UV light.

Good luck

Q. Dear Jake:

Thanks very much for your advise, only one question, by nitro lacquer you mean the kind that are usually applied over wood?

Best regards,

A. Hello Oscar,

Yes, many wood lacquers are made from nitrocellulose, as well as many metal lacquers. This is a cheaper coating to make, you might be able to use a wood lacquer to stop the conductivity on your piece, just need to make sure it adheres well to the metal.

Good luck.
