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.
