Magnesium Substrate Preparation
Plating on Plastics -
Substrate Preparation
The UDIQUE® colloidal pre-treatment process is designed to prepare
plastic substrates for subsequent copper, nickel, chromium, or gold
electroplating. It is the preferred pretreatment in a broad range of
automotive, appliance, jewelry, and consumer hardware applications.
The UDIQUE process consists of the following steps: etching to render
the plastic surface hydrophilic and create a bonding surface;
neutralization to eliminate hexavalent chromium; activation to provide
catalytic sites for subsequent electroless deposition; acceleration to
further enhance catalytic activity; and electroless plating to deposit a
continuous, conductive coating that is well-bonded to the plastic
surface. Because UDIQUE is a system, the entire pretreatment process
delivers performance superior to "home brews" and mix-and-match
formulations. This also makes conversion to the UDIQUE process fast and
economical.
UDIQUE operates with a very wide operating window. This makes the
process easy to control. It also minimizes "skips" in the pre-plate and
eliminates high current density "burns" for fewer rejects. UDIQUE users
also report reduced plating costs, increased production, and lower rack
maintenance costs.
