SF-8300 Cyanide-free Zinc deposition Agent can produce a uniform and dense zinc deposition layer on the aluminum alloy surface, providing good adhesion for subsequent processes such as direct copper plating, nickel plating, tin plating, electroless nickel deposition, etc. The solution does not contain harmful substances such as cyanide, and the complex can biodegrade, which is suitable for plating aluminum alloy cavities.

Tele Aluminum Housing Production Line 2

Used for electroless nickel treatment before plating on aluminum alloys. Specially formulated to remove a small amount of zinc from aluminum. This aluminum alloy with only a thin zinc barrier layer can prevent re-oxidation.

Used to replace cyanide flash copper plating on aluminum after zinc deposition. This process can reduce the need for cyanide and significantly improve the coverage of the flash coating.

1. SF-811 Alkaline Pre-plating Electroless Nickel is a chemical flash nickel plating solution. This alkaline electroless nickel process can deposit a very thin, uniform, and active nickel coating, which can be used for electroless nickel or electroless copper plating and bright nickel plating with good adhesion.

2. As part of the double-layer barrier layer system, the SF-811 process is the second part of the two-step process of zinc plating and nickel double-layer barriers on aluminum alloys before electroless nickel plating. The first step is to plate a Zinc layer on the clean and deoxidized aluminum surface. This layer of zinc prevents aluminum from re-oxidizing, ensuring good adhesion of the final plating layer.

3.  SF-811 Alkaline Pre-plating Electroless Nickel is supplied in four concentrated liquids: SF-811A Alkaline Pre-plating Electroless Nickel Make-up Agent and SF-811C Alkaline Pre-plating Electroless Nickel Reducing Agent for make-up agents; SF-811B Alkaline Pre-plating Electroless Nickel replenisher and SF-811C Alkaline Pre-plating Electroless Nickel Reducing Agent for replenishment. SF-811D Alkaline Pre-plating Electroless Nickel Stabilizer is an additive for the SF-811 Alkaline Pre-plating Electroless Nickel barrier layer. It is used when higher stability of the working solution is required, especially when SF-811 Alkaline Pre-plating Electroless Nickel is not used regularly, and will help prevent metal precipitation and spontaneous decomposition.
