Our functional processes for electroless nickel, tin and cadmium plating are used to give abrasion resistance, solderability or surface lubricity characteristics to the final finish. View our Functional Line Card here.
- Zinc Plating
We offer processes for acid and alkaline non-cyanide based solutions that plate bright zinc deposits that readily accept hexavalent chromates or trivalent passivations.
- Zinc Alloy Plating
Our COLLOY line of products are used for the electroplating of zinc-nickel, zinc-iron and tin-zinc alloy deposits. These processes are easily controlled and widely used in OEM and automotive plating applications.
- Phosphates
We offer a zinc phosphate with a heavy coating weight that has excellent absorption of subsequent applications of rust preventive oil or wax. The oil and wax retention abilities provide excellent corrosion resistance.
- Sealers/Topcoats & Rinse Aids
Our extensive line of sealers and topcoats help extend corrosion resistance or provide surface lubricity characteristics for torque-tension. Rinse aid products can accelerate the drying process and give temporary protection to un-plated areas. Click here to view our Zinc-Chro-SHIELD® Line Card.
- Electroless Nickel Plating
We offer high and mid phosphorous Electroless Nickel plating processes and ELV compliant processes to meet any application or needs. Our processes are characterized by their uniform thickness and hardness.

Our bright and matte tin processes are based on sulfuric acid electrolytes and have excellent solderability. Our cadmium plating brightener gives a deposit with excellent lubricity and is approved in certain aerospace applications.
- Trivalent Passivates
Columbia Chemical’s line of industry-leading trivalent passivates offers superior corrosion resistance, are hexavalent chromium-free, and comply with current ELV, RoHS, and REACH regulations. They consistently meet and exceed OEM standard for corrosion protection. These products offer a trivalent passivation layer that is clear, blue, yellow, black, or iridescent.
