Fengfan OX-108 is a sulfonic ammonium salt anionic surfactant supplied as a light yellow to yellow viscous liquid that dissolves completely in water. In an acid zinc bath it fills the carrier and softener position: it keeps the brightener system evenly distributed through the electrolyte and carries brightness into the areas where a zinc deposit usually thins, dulls or burns.
Potassium chloride zinc plating is where it is used most, and the same grade also works in sodium zinc electrolytes. Rack work, barrel work and shops running both at once use the same softener level, so a single drum serves both lines.
It is designed to sit alongside the brighteners acid zinc shops already run. OCBA and BAR are both emulsified and dispersed by it, and it stays compatible with the other addition agents in the bath rather than competing with them. Where a line already doses OX-301 or OX-401, putting this product in the softener position gives the fullest result.
The liquid carries a slight odour and a solid content of at least 70%, so the dosing volume stays predictable from one batch to the next. For a potassium chloride line starting from scratch, it is one of the acid zinc plating chemicals that has to be specified at the beginning rather than added once the bath is already running.

Used as the softener, the product is dosed at 200–250 g/L. That is the figure to build the bath around; the point you work at inside the range is set by the brightness you need and by how much organic carrier the rest of the system already contributes.
Pairing changes the result more than pushing the dose does. Run with OX-301 at 30–50 g/L, or with OX-401 at the same 30–50 g/L, and the overall performance of the bath is better than either additive gives alone. The three together cover the current density curve from the recessed faces out to the edges.
Rack and barrel lines use the same softener figure. What changes between them is agitation and current density, not the carrier concentration.
Before a full changeover, run a hull cell on your own solution at your own temperature and confirm the panel. A trial bath will tell you more about the fit than any general recommendation, and it keeps the change reversible if the brightener system you run behaves differently from the one this grade was set against.
This product sits in one segment of a much wider range. Alongside acid zinc we supply alkaline zinc and zinc nickel plating processes, copper, bright and electroless nickel, tin, silver and gold for electronics, and the passivation and sealing stages that follow them. A plating shop can cover a whole sequence without splitting an order across several suppliers.
For a line running potassium chloride zinc, the acid zinc plating chemicals are the relevant part of that range: the carrier, the brightener system and the purifier, specified together so they are known to work in the same bath rather than being matched by trial and error.
We also support industrial metal plating outside the zinc segment. Barrel lines, rack lines, continuous lines and job shops all draw on the same catalogue, and the technical contact who answers a dosing question on this product can answer the same question for the next stage of the process. Electroless nickel plating has to deliver a uniform coating without any electrical current, which is where bath control matters most. Fengfan's surfactant aids the dispersion of nickel particles through the bath, so the deposit builds up smooth and even and the plated items gain both durability and appearance. Better dispersion also means less waste and higher throughput, which makes the process more cost effective for clients weighing it against electro plating options.
Nickel work is a separate part of the range, and the chemistry behind it is not the same as a zinc bath. An electroless process depends on a reducer system and a controlled nickel concentration rather than on a zinc carrier, so the additives are chosen for a different job entirely. We supply FF-6000 for a medium-phosphorus deposit, Nickel Purify P3 for keeping a bright nickel bath clear of accumulated metal ions, and Nickel Guard 71 for post-plating surface protection.
Where the two worlds touch is the way a solution wets the work. Dispersion and even thickness come from the same interfacial behaviour a carrier provides in acid zinc, which is why shops that run both processes tend to buy their addition agents from a single source.
What this product cannot do is act as a nickel additive. Keep it in the zinc bath and use the nickel-specific products on nickel lines; substituting one for the other is the fastest way to lose a bath that was previously running well.
The surfactant side of the catalogue is broader than one grade. OX-401 is a low-foam grade used as a brightener or softener in acid zinc; OX-608 is a low-foaming nonionic with a high cloud point for acid zinc baths; OS-8 is an emulsifier for potassium chloride zinc. The C10 and C13 alcohol ethoxylate series, JC-660 and TL-110 cover wetting, emulsifying and defoaming duties outside the plating tank as well.
This product is the sulfonic ammonium salt anionic surfactant in that family. It is the one to specify when the job is a carrier for a potassium chloride bath rather than a low-foam wetter or a general emulsifier.
Read the family as a set of surface active agent options, not as substitutes for one another. Each is dosed at its own level and does its own job, and an electroless nickel plating line draws its wetting agents from a different part of the range again.
A bath is only half of what a line needs. Tanks, barrels, racks, filtration and the ancillary hardware that keeps a solution in condition appear in the same catalogue as the chemistry, so a new line can be specified in one conversation rather than three.
Matching hardware to the process matters more in acid zinc than it looks. Agitation, filtration and temperature control all change how a carrier behaves, and a softener that performs well in one tank can under-perform in another simply because the solution is not moving properly. When a customer describes brightness falling away at the top of the current range, the answer is sometimes in the pump rather than the drum.
We quote the equipment alongside the chemical so the two arrive specified for each other, and spare barrels, racks and filter media can be added to a chemical order to keep consumables and chemistry on one delivery schedule.

Wuhan Fengfan International Trade Co., Ltd. is the international trading arm of Wuhan Fengfan Electrochemical Technology Co., Ltd., a company founded in 1984 and part of the Chinese surface finishing industry ever since. More than four decades in the field is why the catalogue runs from a single carrier like this one through to a complete anodizing line.
The group's site in Dongxihu District, Wuhan, handles the surface treatment additives, and a dedicated pilot laboratory supports process development, green electroplating processes in particular. That laboratory is also where a customer's bath problem can be reproduced under controlled conditions instead of guessed at over the phone.
For a buyer the practical effect is simple: the person quoting a drum of carrier is backed by an organisation that has been formulating for plating shops for decades. Batch records and technical answers come from the same place as the product.
As an experienced surfactants manufacturer, we build a diverse range of products for the different jobs a production line asks of them. The range includes Fengfan OX-108, a sulfonic ammonium salt anionic surfactant engineered to hold up in demanding applications, and every grade is developed to improve efficiency and performance rather than simply fill a drum. Formulation work and testing sit behind each product, so what you specify is what you receive. Tell us the system you are running and we will point you to the grade that fits it.
Paint chemicals suppliers sit at the front of the finishing chain, and the surfactant they choose shapes how the finished coating behaves. Fengfan's surfactant improves the stability of paint chemical formulations and their application properties, which shows up on the substrate as better adhesion and a smoother finish. For industries working with anodized aluminum and other anodized metal surfaces, that difference is visible on the finished part. Suppliers who build it into their range can offer better performing products and, in turn, strengthen their position with existing customers.
Choosing the right match is where most sourcing decisions stall. As a trading supplier, we keep one point of contact from first enquiry to after-sales: tell us what you are making and the conditions you work under, and we shortlist the closest matches from our supplier network, compare specifications and arrange samples before you commit to a bulk order. If something does not behave as expected, we work with the supplying partner on the cause and a practical fix, and stay with the case until it is settled. Email, WeChat or WhatsApp enquiries get a reply within 24 hours.
It takes the carrier and softener position. As a sulfonic ammonium salt anionic surfactant it keeps the brightener distributed through the electrolyte and pushes brightness into the high and middle current density areas, which is where acid zinc deposits most often burn or dull. Recessed faces and the low-current side of a part fill out rather than staying grey.
200–250 g/L is the working figure. If the line already runs OX-301 or OX-401, dose those at 30–50 g/L alongside it and the overall performance of the bath is better than the carrier gives on its own. Confirm the final point with a hull cell on your own solution before a full changeover — the brightener you use and the shape of your work will move it inside that range.
Yes. The same grade runs on rack and barrel equipment and the softener figure does not change between them; what differs is agitation and current density. Barrel work benefits from the dispersing behaviour in particular, because a turning load has to plate evenly on faces that keep presenting themselves to the solution.
It does. Both o-chlorobenzaldehyde and benzalacetone are emulsified and dispersed by the carrier, so the brightener stays distributed instead of separating or oiling out. That also keeps it compatible with the other addition agents in a metal plating process where the brightener is dosed separately from the carrier.
Sodium zinc, yes — the same product takes the carrier position there, so a shop moving between potassium chloride and sodium electrolytes does not need a second softener. Zinc nickel plating is a different system: the alloy bath uses its own coordination agents and a trivalent passivate afterwards, and substituting this carrier will not give you the same deposit.
The pH of 3.0–6.0 is measured on a 1% aqueous solution, so it describes the product as supplied rather than the working bath. Solid content is at least 70%, which is what keeps the dosing volume predictable, and the quoted cloud point is >1.1 °C. As with any surface active agent, dose against the specification by weight or volume rather than by eye.
No. Anodizing lines and electroless nickel plating lines use their own addition agents, and this carrier belongs in a zinc electrolyte. If you are looking for a wetting agent for a nickel bath or an additive for an anodizing tank, we supply those from other parts of the range and will point you to the right one rather than the closest one.
We can work around your line rather than the other way round. Tell the sales team your bath volume, the brightener system you run and the pack size you want, and they will confirm what is possible for your order, including whether a trial quantity makes sense before a full drum goes on the tank. For metal plating services running several lines, the same conversation can cover the whole addition set.
