Since 1995, Ronatec C2C has been a pioneer in the Trivalent Chrome Plating market. While many trivalent chromium systems are associated with certain color problems, notably darkness and a noticeable lack of shininess, Ronatec has worked to develop both liquid and powdered versions which all but eliminate these issues.
An alternative to hexavalent chromium, trivalent chromium appears to hold the most promise. Trivalent chrome plating provides a safer and environmentally acceptable alternative. It decreases health hazards from airborne chromium. Waste treatment and disposal costs are reduced because the process uses no hexavalent chromium.
Trivalent systems can save an electroplating shop money in a number of ways They include lower metal concentrations and current density, and reduced dragout, fumes, and liability. By installing a trivalent system, you avoid the need to reduce hexavalent chromium wastes to their trivalent state.
Trivalent Chrome Plating Processes
Trionyx
A RoHS and ELV compliant, and automotive approved black trivalent chromium process.
Aluminescent
Aluminescent is a powdered product used to form a chromate conversion coating on aluminum surfaces without the use of hexavalent chromium. The process provides excellent corrosion protection at low cost and forms a base for paint, lacquer, or rubber bonding. The chromate can be applied by dip, spray, brush, swab, or roll coating, requires no electric current, cooling or exhaust. Aluminescent yields clear, slightly iridescent films while forming a protective surface with lower electrical resistance than anodizing. Aluminescent is suitable for both wrought and cast aluminum alloys and is designed for ease of operation with minimum control.
TC-920 PROCESS
A new generation high performance chloride-based trivalent chrome process that is effective and easy to use. It has the ability to provide uniform performance over a wide range of current densities and operating conditions easily and economically. It is unaffected by current interruptions, and provides much better throwing power and coverage than hex chrome. The formulation performs better in presence of copper, zinc, iron, and nickel, the metallic impurities that most seriously affect deposit color and low current density performance. TC-920 provides a uniform, blue-bright deposit appearance that closely resembles hexavalent chrome coatings.
