Potassium Formate Technical Data Sheet: What Industrial Buyers Should Check

A potassium formate technical data sheet, usually called a TDS, is one of the first documents an industrial buyer should review before approving a new potassium formate supplier.

It gives you the basic technical picture of the product: what it is, what concentration or purity is available, what the material looks like, its physical properties, typical applications, storage recommendations and sometimes important impurity limits.

But there is one thing worth clearing up from the beginning.

A TDS is not the same as a batch certificate.

It tells you what the product is normally designed to meet. It does not necessarily tell you the exact laboratory result of the drum, IBC or bag sitting in your warehouse.

For that, you need the COA.

Understanding this difference makes potassium formate purchasing much easier, especially for oilfield, refrigeration, heat-transfer and other technical applications.

What Is a Potassium Formate TDS?

A Technical Data Sheet is a product-level technical document provided by a manufacturer or supplier.

For potassium formate, it normally includes information such as:

• Chemical name
• CAS number
• Molecular formula
• Molecular weight
• Product concentration or purity
• Appearance
• Density for liquid grades
• pH
• Solubility
• Important impurity limits
• Recommended applications
• Packaging
• Storage information

A good TDS should allow a technical or procurement team to make an initial decision about whether the product is worth testing.

It doesn't have to be 20 pages long.

Actually, for a fairly straightforward chemical like potassium formate, a clear two- or three-page TDS can often be more useful than a very long marketing brochure.

Basic Chemical Information

The first section of a potassium formate technical data sheet usually contains product identification.

Typical information includes:

Item	Typical Information
Chemical Name	Potassium Formate
Molecular Formula	HCOOK
CAS Number	590-29-4
Molecular Weight	Approx. 84.12 g/mol
Product Forms	Concentrated liquid / crystalline solid
Common Liquid Grade	Approx. 75% solution
Common Solid Grade	Approx. 96% or higher
Solubility	Highly soluble in water

This section sounds basic, but it matters when documents are being reviewed by purchasing, laboratory, warehouse and regulatory teams in different countries.

Correct product identification avoids a surprising amount of confusion.

What Should a 75% Potassium Formate TDS Include?

For liquid potassium formate, concentration is only one part of the technical picture.

A typical TDS may include the following information:

Concentration

The product may be specified as approximately 75% potassium formate by weight.

This means 100 kg of solution contains roughly 75 kg of potassium formate, with the remaining mass mainly being water.

Appearance

Commercial potassium formate solution is normally described as a clear, colorless or slightly colored liquid.

Unexpected haze, sediment or contamination may require further investigation.

Density

Density is especially useful for liquid potassium formate because it can help with receiving inspection and formulation calculations.

A meaningful density value should always state the measurement temperature.

Writing:

Density: 1.57 g/cm³

is less useful than:

Density at 25°C: approximately 1.57–1.58 g/cm³

Temperature matters when comparing liquid-density data.

pH

Potassium formate solutions are normally mildly alkaline.

The pH may be relevant to formulation compatibility, corrosion-control programs and downstream processing.

Solubility

Potassium formate is highly soluble in water, which is one reason concentrated liquid grades can be produced and easily diluted.

What Should a Solid Potassium Formate TDS Include?

The emphasis changes a little for solid grades.

For a 96% or higher solid potassium formate, the TDS may focus more on:

• Potassium formate assay
• Appearance
• Moisture
• Chloride
• Carbonate
• Insoluble matter
• Solubility
• Storage conditions

Density of the dry product is generally less important than it is for a finished brine.

The buyer is usually going to dissolve the material and prepare the required concentration locally.

Liquid vs Solid TDS Parameters

Parameter	75% Liquid	96% Solid
Potassium Formate Content	Important	Important
Appearance	Clear liquid	White crystalline solid
Density	Very important	Normally secondary
pH	Commonly listed	May be tested in solution
Moisture	Not a main parameter	Important
Chloride	Important	Important
Carbonate	May be controlled	May be controlled
Insoluble Matter	Important for clear fluids	Important after dissolution
Storage	Temperature / contamination	Moisture protection
Handling	Pumps, tanks, IBCs	Bags, dry handling

This is why one generic potassium formate TDS should not simply be copied for every physical form.

Why Chloride May Appear on the TDS

Potassium formate itself does not contain chloride in its molecular formula.

However, commercial industrial products may contain trace chloride from raw materials or manufacturing processes.

For some applications this doesn't matter very much.

For others, particularly corrosion-sensitive oilfield or heat-transfer systems, the chloride limit can be more important.

Buyers should also check how the supplier reports chloride.

It may be listed as:

• Cl⁻
• Chloride
• KCl equivalent

Those values should not be compared blindly without understanding the reporting basis.

This is one of those small technical details that can create a lot of unnecessary discussion later.

Carbonate and Alkalinity

Potassium carbonate or related alkalinity may also appear on a technical data sheet.

These parameters can influence:

• pH
• Fluid chemistry
• Compatibility with other additives
• Final formulation performance

For general industrial use, relatively small differences may not matter.

For a carefully controlled drilling or completion fluid, the technical team may choose to set tighter limits.

Again, application comes first.

There is no point demanding an ultra-tight specification if the finished process receives no benefit from it.

TDS vs COA vs SDS

These three documents are frequently requested together, but they do very different jobs.

Document	Main Purpose	What It Tells You
TDS	Product technical information	Standard or typical properties
COA	Batch quality verification	Actual analytical results
SDS	Safety and handling	Hazards, PPE, storage and emergency information

Technical Data Sheet

The TDS helps you understand the product before purchasing.

Certificate of Analysis

The COA helps you verify the batch being supplied.

If the TDS says:

Potassium Formate ≥96%

the COA might show:

Potassium Formate 97.0%

That actual number is the result from the tested batch.

Safety Data Sheet

The SDS is primarily about safe use.

It covers areas such as:

• Personal protective equipment
• Handling precautions
• Storage
• Spill procedures
• First aid
• Transport information

The SDS is important, but it is not a replacement for the TDS.

Why Oilfield Buyers Need More Than a Generic TDS

Oilfield applications usually require a closer technical review.

Potassium formate can be used in:

• Drilling fluids
• Drill-in fluids
• Completion fluids
• Workover fluids
• Clear brines
• Shale-control systems

For these applications, the standard commercial TDS may only be the starting point.

A completion-fluid company may also want information about:

• Chloride
• Iron
• Insoluble matter
• Turbidity
• Density-concentration relationship
• Crystallization behavior
• Batch consistency

Some of these parameters may be provided separately rather than on the standard TDS.

If your project needs the information, ask for it.

Suppliers cannot guess every technical requirement from the words “oilfield grade.”

Reading the Density Data Correctly

For potassium formate solution, density deserves special attention.

A concentrated potassium formate solution may be used to formulate higher-density clear brines.

As potassium formate concentration changes, density also changes.

But concentration is not the only variable.

Density can also be affected by:

• Temperature
• Product purity
• Dissolved impurities
• Measurement method

So if you are preparing an oilfield fluid, don't take one density number from a TDS and assume it applies to every concentration.

Ask for density-concentration data if needed.

For serious brine engineering, one number isn't enough.

What About Crystallization Temperature?

This becomes more important as potassium formate concentration increases.

Concentrated salt solutions can crystallize if exposed to unsuitable temperatures.

For customers operating in:

• Canada
• Northern Europe
• Central Asia
• Offshore winter environments
• Cold-storage facilities

this may be a very practical issue.

A good technical discussion should therefore consider the minimum expected storage and operating temperature.

If crystallization data is important for the project but isn't shown on the standard TDS, request additional technical information.

Don't wait until the IBC is sitting outside in January.

Using the TDS for Supplier Comparison

One of the best uses of a potassium formate TDS is supplier comparison.

Instead of comparing only:

Supplier A: $X/MT
Supplier B: $Y/MT

compare technical data first.

Supplier Qualification Checklist

Question	What to Check
Same product form?	Liquid vs solid
Same concentration?	70%, 75%, 96%, etc.
Same assay basis?	Confirm testing method
Same chloride limit?	Check reporting basis
Same impurity control?	Carbonate, iron, insolubles
Same density condition?	Check temperature
COA available?	Confirm recent batch data
SDS available?	Verify current safety document
Packaging suitable?	IBC, bag, jumbo bag
Storage requirement acceptable?	Especially cold or humid conditions

This makes the purchasing comparison much more meaningful.

A cheaper product with a different specification is not really a cheaper version of the same thing.

It may simply be a different product.

Can a TDS Be Customized?

The standard TDS normally describes the supplier's regular commercial grade.

For large industrial projects, however, customers may have their own technical specification.

For example, a buyer may require:

• Lower chloride
• Tighter concentration tolerance
• Controlled insoluble matter
• Specific packaging
• Additional testing

In that case, the customer specification and purchase agreement become more important than the supplier's generic TDS.

Before promising custom limits, the supplier should confirm whether production and quality control can consistently meet them.

One special batch is not enough for a long-term supply program.

How to Request a Potassium Formate TDS

A practical inquiry can be very short:

Please provide the latest Technical Data Sheet for Potassium Formate 75% Solution, together with a recent COA and SDS.
Application: Completion Brine
Estimated Quantity: 40 MT
Please also confirm density, chloride, insoluble matter and available packaging.

For a solid grade:

Please provide the current TDS for Potassium Formate 96% Solid, including assay, moisture, chloride, carbonate and packaging details.

This tells the supplier exactly what your technical team needs.

Vanchor supplies potassium formate in concentrated liquid and solid forms for oilfield, heat-transfer, refrigeration, deicing and other industrial applications. Buyers can request the current TDS, COA, SDS and commercial quotation according to their required product form and project specification.

Final Thoughts

A potassium formate technical data sheet is not just paperwork attached to a chemical quotation.

It is the first technical filter between a product name and a real industrial purchase.

The TDS should help you understand concentration, physical form, density, pH, solubility, impurities, storage and intended application.

But don't stop there.

Use the TDS to select the product, the COA to confirm the batch, and the SDS to manage safety and handling.

For technical applications such as drilling or completion fluids, request additional data if the standard sheet does not cover the parameters your project needs.

A good potassium formate supplier should not only be able to send a TDS.

They should be able to explain what the numbers on that TDS actually mean.

FAQ

What is a potassium formate technical data sheet?

It is a product document describing the standard or typical technical properties of potassium formate, including concentration, physical properties and relevant specifications.

Is a TDS the same as a COA?

No. A TDS describes the standard product, while a COA reports analytical results for a specific or representative production batch.

What should a potassium formate 75% TDS include?

It commonly includes concentration, appearance, density, pH, solubility and relevant impurity information.

What should a potassium formate solid TDS include?

Important information may include assay, appearance, moisture, chloride, carbonate, insoluble matter, solubility and storage recommendations.

Do I also need an SDS?

Yes. The SDS provides safety, handling, storage and emergency-response information that is not the main purpose of the TDS.

Can I request additional technical parameters?

Yes. Industrial buyers can request additional data or customized specifications when their application requires tighter impurity or performance limits.
