Protection for Patina Finishes on Brass Watch Dials
We are one of the leading manufactures of watch dials and hands in India. We are carrying out various types of electroplating processes and also some patina finishes on brass. In patina finish we are facing some problem that is we are not able to give protection for the finished surface as the colour discolours after some time. I would like to know any dip type water based clear lacquer is available for the process and also the manufacturer of water based dip lacquers. We need only dip type as our component watch hands very small in size.
