SEM Analysis at 1000x and 5000x SF-6331 Roughening Wetting Agent can be used for plastic workpieces that require chromic acid and sulfuric acid micro etching. This product can reduce the surface tension of micro etching, uniformly micro etch the plastic surface, and promote the rapid detachment of the solution from the workpiece.

The main function of SF-6351CR reducing agent is to reduce hexavalent chromium (from the etching solution) to trivalent chromium, preventing the subsequent process solutions, especially the activator, from being contaminated and functionally impaired by hexavalent chromium. This product causes minimal damage when carried into the activator, effectively protecting the activator and extending its lifespan. Furthermore, it has no irritating odor during operation, which helps improve the factory environment.

SF-6391A plating on plastic de-gelling agent is an accelerator used in the pretreatment of plating on plastic, following the colloidal palladium activation step. During the activation step, both tin and palladium are adsorbed onto the plastic surface. The plastic electroplating de-gelling agent can highly selectively remove tin, effectively promoting the activity of palladium. It features a stable working solution, long service life, a single-component system, and simple operation.

SF-6501 Electroless Nickel for Plastics can deposit a smooth, continuous, and highly adhesive nickel layer on the activated plastics surface. It has the characteristics of resistance to contact sintering, low operation temperature, and low cost.

SF-481 Semi-bright Nickel Plating Additive is suitable for multi-layer nickel plating on plastic products, automobiles, motorcycles, sanitary parts, and metal furniture. Its function is to produce a semi-bright nickel coating with excellent ductility and leveling force. The coating does not contain sulfur and has a columnar structure. It has the characteristics of good coating adhesion, stable potential difference, excellent corrosion resistance, good dispersion ability of plating solution, strong coverage ability, low consumption, few decomposition products, no need for rinsing, and easy maintenance.

Sanfu bright nickel plating additives are suitable for rack plating nickel on high-end products such as plating on plastic. According to customer processes and product requirements, they are including SF-8861 bright nickel plating process, SF-8863 bright nickel plating process, and SF-921 pearl nickel electroplating process.

SF-8861 Bright Nickel Plating Process Features rapid brightening and leveling capabilities, with a fast deposition rate. Produces a complete coating with good ductility and leveling properties. Demonstrates good performance in CASS (Copper Accelerated Acetic Acid Salt Spray) tests and corrosion resistance tests. Offers a wide operating range, is easy to control, and has low cost.

SF-8863 Bright Nickel Plating Process 1, The SF-8863 bright nickel process can produce a white nickel coating with good leveling, uniform flexibility, and a mirror-like brightness. 2, The plating solution has excellent throwing power. SF-921 Pearl Nickel Electroplating Process

The SF-921 pearl nickel electroplating process can deposit a decorative nickel coating with excellent fineness and uniformity, and a matte finish on the substrate. The surface has almost no gloss and exhibits excellent resistance to touch and scratches. The pearl nickel coating can be subsequently plated with chromium and other decorative coatings.

Sanfu bright nickel plating additives are suitable for rack plating nickel on high-end products such as plating on plastic. According to customer processes and product requirements, they are including SF-8861 bright nickel plating process, SF-8863 bright nickel plating process, and SF-921 pearl nickel electroplating process.

SF-3511 nickel sealing electroplating process is suitable for high-decoration, high-corrosion resistance products such as plating on plastic and high-end products like sanitary ware for multilayer nickel electroplating. Its function is to plate a thin, bright flash nickel layer (approximately 1.5-2.5 microns thick) on top of the bright nickel-plated layer, and subsequently generate micropores in the chromium plating layer. This improves the corrosion resistance of the composite coating and features stable plating solution, wide process range, and convenient solution maintenance.

SF-8681 High-performance Decorative Chromium Plating is applied to decorative bright chromium coatings. It has the characteristics of wide current density range, strong coverage ability, high chromic acid concentration, strong conductivity and resistance to impurity contamination, and promoting the stability of plating solution components.

SF-112 anode electrolytic stripping agent is used for rack stripping. Under a current density of 50 amperes per square decimeter, it can remove a coating thickness of 10 microns per minute. It can simultaneously strip copper, nickel, and chromium coatings. It features operational safety, easy cleaning of treated racks, no damage to green hook colloid, no damage to stainless steel substrate hooks, extended service life of racks, and is beneficial for controlling cost-effectiveness.
