Stannous Chloride (Tin(II) Chloride) Supplier in Malaysia
- Also known as
- tin(II) Chloride
- Tin Chloride
- Tin Dichloride
- SnCl2
Stannous chloride supplier for electroplating, glass, textile and laboratory buyers in Malaysia. Also called tin(II) chloride or tin dichloride, and traded loosely as tin chloride, it is a water-soluble white to off-white tin salt and a strong reducing agent.
The first choice is the hydrate state. Dihydrate crystals or flakes are the usual solid, while anhydrous powder is taken where water of crystallisation must be kept out of the reaction. Grade runs from technical and electroplating material through reagent purity to food grade E512, and stabilised aqueous solutions are supplied for lines that prefer liquid dosing.
Platers use it to sensitise plastics and circuit boards before metallisation and to make up tin plating baths. Mirror silvering, textile mordanting and discharge work, canned-food colour retention and laboratory reduction chemistry account for most of the remaining demand.
Only the +2 oxidation state is covered here: stannous chloride is the tin(II) compound, and stannic chloride, tin(IV), is a separate product ordered by name. Send the hydrate form, grade, quantity and delivery location with your enquiry, and availability, packing and documentation are confirmed with the quotation.

Stannous Chloride grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Stannous chloride dihydrate, technical grade | white to off-white crystals or flakes | — | Tin plating bath make-up and the sensitising step ahead of electroless metallisation on plastics and printed circuit substrates, where a soluble tin(II) source is charged into an acidic bath. | Confirm the required pack format with the quotation. |
| Anhydrous stannous chloride | white to off-white powder or crystalline solid | — | Synthesis, catalyst and intermediate chemistry where water of crystallisation has to be excluded and the tin charge is calculated on an anhydrous basis. | Confirm the required pack format with the quotation. |
| Reagent grade stannous chloride dihydrate | high-purity crystals | — | Laboratory reducing agent for colorimetric determinations, tin and molybdenum chemistry, and reduction steps in radiopharmaceutical preparation kits that call for a tin(II) source. | Confirm the required pack format with the quotation. |
| Food grade stannous chloride (E512) | white crystals | — | Antioxidant and colour-retention additive in canned vegetables and similar packed foods where E512 is named in the formulation. Supply is subject to applicable requirements. | Confirm the required pack format with the quotation. |
| Stabilised stannous chloride solution | clear acidic aqueous solution | — | Ready liquid dosing for plating pretreatment lines that would rather not dissolve crystals on site. State the target tin concentration and acidity with the enquiry. | Confirm the required pack format with the quotation. |

Stannous Chloride applications
Safety and handling
- Classification
- irritant
Keep containers tightly closed in a cool, dry place away from oxidising agents, since tin(II) oxidises to tin(IV) in air and moisture, and the dihydrate takes up water. Solutions are acidic, attack many metals and lose strength as they age, so make them up in resistant equipment and use gloves and eye protection. Follow the safety information for the grade quoted.
Common questions about stannous chloride
Is stannous chloride the same as tin(II) chloride?
Yes. Tin(II) chloride is the systematic name, tin dichloride and SnCl2 refer to the same compound, and much of the trade simply says tin chloride. E512 is the additive number used when the material is supplied for food use.
What is the difference between stannous chloride and stannic chloride?
They are different products. Stannous chloride carries tin in the +2 oxidation state and behaves as a reducing agent, while stannic chloride is the tin(IV) compound with its own formula, physical state and handling. If a process calls for the tin(IV) material, order stannic chloride by name.
Should I order the dihydrate or the anhydrous form?
The dihydrate is the crystal or flake form usually traded and it dissolves readily for plating and analytical work. Anhydrous powder is chosen where water of crystallisation interferes with the reaction or where the charge is calculated on a strict anhydrous basis. State which basis your dosage figures assume.
Why do stannous chloride solutions go cloudy and lose strength?
Tin(II) oxidises to tin(IV) on contact with air and dilute solutions also hydrolyse, so a stored solution slowly turns hazy and reduces less. Working solutions are commonly acidified and made up close to the point of use, and a stabilised solution can be requested instead of crystals.
Which grade suits electroplating and electroless plating pretreatment?
Technical or electroplating grade dihydrate is the usual choice for tin plating baths and for sensitising boards and plastics before metallisation. Send the bath specification, including any limits on tin(IV), free acid or iron, so the grade can be matched to the line.
What details are needed for a stannous chloride price enquiry?
Provide the hydrate form, grade, target assay or impurity limits, intended process, quantity and delivery location. Mention any documentation you need and the timing you are working towards so the quotation covers the whole requirement.
