CHKO₂ Potassium Formate | High-Performance Formate Solution for Drilling & Deicing Applications
Shanxi Zhaoyi Chemical Co., Ltd. was founded in 1988. We are a formate chemical manufacturer, and more than 35 years of R&D and production experience sit behind us. Our plant is standardized and covers 27,000 m². Steady output reaches 150,000 tons a year. Out of that base we supply industrial chemical solutions to clients around the world. CHKO₂ Potassium Formate (CAS NO.: 590-29-4) is one of our products, and it comes in industrial grade. Buyers can order it as a white crystalline powder or as a colorless transparent liquid. Water solubility is excellent, and the product resists extremely low temperatures, down to -50°C. ISO, KOSHER and HALAL certifications back it up. Oilfield drilling fluid preparation is one job it handles well. Roads and airports use it for deicing. It fits other industrial processing work too, with stable and reliable results. Clients in Europe, America, Asia and other global markets buy from us.

Key Features & Benefits
This product fits many different industries. It stands up to the tough conditions those sectors work in, and the performance advantages add up. Companies that use it spend less on operations and keep their processes running more steadily:
Eco-Friendly & Low-Corrosion Performance: Traditional chloride-based chemicals act in a different way. This formate solution breaks down well in nature, so the damage to the environment stays tiny. It also cuts the risk of corrosion on industrial equipment. The same holds for roads, bridges and airport infrastructure. Over the long run, companies put less money into maintenance.
Ultra-Wide Temperature Adaptability: It keeps working in very hot drilling conditions, even above 200°C. At the other end, deicing still works well when temperatures drop to -50°C. This mix of heat and cold resistance lets your industrial operations stay flexible and run with fewer breaks.
High Solubility & Stable Fluid State: The product dissolves fully in water. No solids float in it, and no precipitation forms. A brine made with it can reach a top density of 1.57 g/cm³. Fluid systems then run in a stable way over time, so equipment blockage and fluid failure are avoided.
Strong Multi-Scenario Compatibility: With stable chemical properties and moderate molecular weight of 84.12, it adapts to diversified application scenarios including oilfield exploitation, winter road deicing, leather processing and industrial manufacturing, meeting differentiated production demands of various industries.

How It Works
Relying on molecular structure characteristics, this product forms a stable and efficient working mechanism after dissolution, solving multiple industry pain points such as wellbore instability, infrastructure corrosion and inefficient industrial reaction:
Oilfield Drilling Stabilization Mechanism: Drop the product in water and it comes apart. You end up with potassium ions and formate ions. At the shale surface, those potassium ions swap places with sodium ions. Clay then stops taking on water and stops swelling. That is what keeps the wellbore steady. The brine holds no solids and carries a high density, so the reservoir formation takes no damage at all. Long-cycle HPHT drilling jobs are a good fit for it.
Low-Temperature Deicing, How It Works: Formate ions do a specific job in deicing work. They break apart the hydrogen bond structure inside ice crystals. Water's freezing point then drops fast. The result? Ice and snow melt quickly. Nothing corrodes. Metal equipment and concrete facilities stay free of structural damage. Infrastructure keeps working safely and stays intact all winter.
Help in Industrial Processes: In factory production lines, this substance works as a steady pH buffer. It also keeps catalysts stable. Chemical reactions run more efficiently. System pH stays in range. Corrosive substances get isolated. Production equipment is protected as a result, and less waste is discharged.
Applications
With ultra-wide temperature resistance, zero formation damage, low corrosion and environmental protection advantages, this product covers oilfield exploitation, infrastructure maintenance, light industry processing and industrial manufacturing, with mature and reliable industrial application schemes:
Oilfield Drilling & Completion: High-density drilling and completion fluids with no solids are where this product fits. HPHT deep wells are a good match too. Shale swelling gets held back. Damage to the reservoir formation goes down. Even under extreme downhole heat, fluid performance stays steady. Drilling then runs in a safe and efficient way.
Snow & Ice Management: Airports count on it to melt ice and clear snow off runways. Bridge decks get the same treatment. City roads and other busy traffic spots use it too. Old chloride deicers rust metal and make concrete flake away. This one does not. Even winters that drop to extreme lows are no problem for it.
Leather Processing: It works as a pH buffering agent during tanning and finishing. Once it goes in, the solution pH holds steady. Tanning results come out better. Less chemical waste leaves the plant. That puts manufacturers closer to green production.
Industrial Manufacturing: Cement prep work uses it. Printing dye processing does as well. So does fine chemical synthesis. Catalytic performance stays steady with it, and so does behavior under heat. Quality stays even across long, nonstop production runs.
Heat Transfer Systems: The product works here as an antifreeze that does not corrode metal. It goes into circulating systems for industrial heating and cooling. Pipes and equipment are protected from frost damage and corrosion. So the heat transfer equipment lasts longer.

Packaging Options
Solid products and liquids both come in our packaging. Standard formats are what we use, and we can change them to suit your order. Small runs are fine, and so are big ones. The shipping method matters, and so does how the product, CHKO₂ Potassium Formate, is used on site:
Solid Product Packaging: Our standard bag is a woven one that holds 25kg. Inside sits a polyethylene liner, which keeps moisture out. Carrying these by hand is simple, and they suit small batches. Bulk orders can arrive in 1000kg ton-bags. Warehouse storage gets easier too. Mechanical handling also runs faster.
Liquid Product Packaging: Medium batches and on-site dosing call for our 1000L standard IBC tanks. When large volumes cross borders in containers, they ship in custom flexibag packaging. That keeps international logistics costs down.
Every package we ship meets international shipping standards. Moisture protection holds up well. Anti-pollution performance does too. Each package shows clear product specs, plus batch numbers and safety notes. Full traceability comes with that.

Manufacturing Process
Precision equipment drives how we run the synthesis. The raw materials we pick are high-purity. During reactions, the temperature stays fixed. That lets us get purity and yield up to their top levels. Temperature and concentration stay tightly controlled at the crystallization step. The result is particles that come out the same size. They also dissolve and handle more easily.
Several purification stages are part of the production line. Filtration and washing are built in too. Trace impurities come out completely. During the last drying step, moisture content stays tightly controlled. This keeps the product from breaking down in heat. It also stops performance loss.
A technical and quality control team of 60 people watches every production node in real time and pulls samples for inspection. Testing of performance and composition is strict. Each batch has to meet industrial premium standards.

FAQ
Q: Can this product be used safely in drinking water system projects?
A: A1: The product carries a food-grade certification. Rules differ from region to region, though, and each potable water project still has to meet the ones where it goes in. Get in touch with our team. We will walk you through the compliance steps and send the documents you need.
Q: Which storage method stops the product from spoiling?
A: A2: Store it in a cool, dry place with good airflow. Keep heat away from it. Air that holds moisture is a problem as well. Solid grades need to be sealed tight. If moisture gets in, the powder soaks it up and turns lumpy.
Q: When it comes to oilfield drilling, how does it stack up against potassium chloride?
A: A3: Shale inhibition comes out stronger, and the wellbore holds up better. No chloride sits in the formula. So the corrosion issues tied to traditional potassium chloride never show up. Because of that, downhole equipment loss drops a lot. Maintenance costs fall too.
Q: Is it safe to blend this product with other industrial chemicals?
A: A4: Whether chemicals work well together comes down to the application. Talk to our technical team before any big mixing job. They can test how the chemicals react and pass on their advice. That keeps the work safe, and results stay steady.
Q: How small can my order be?
A: A5: Order sizes stay flexible with us. You can start with 25kg. Booking a full container is fine too. Tell us your figures and we will build a supply plan that suits you.
