- Product Description
HCO₂K Potassium Formate – Premium Grade Industrial Chemical for Drilling, Deicing & Multi-Industry Applications
Founded in 1988, SHANXI ZHAOYI CHEMICAL CO., LTD. is a professional industrial chemical manufacturer with mature production and export experience. Operating a 27,000 m² standardized production base with a stable annual output of 150,000 tons, we specialize in supplying high-purity industrial chemicals for global multi-industry scenarios. Our HCO₂K Potassium Formate (CAS 590-29-4) boasts a minimum purity of 97%, available in white crystalline powder and clear liquid forms. Tailored for core industrial applications, it supports high-density oilfield drilling fluid preparation with a maximum density of 1.57 g/cm³, ultra-low temperature deicing down to -50°C, and various industrial processing processes. Certified by ISO, KOSHER and HALAL, our products deliver stable and compliant quality, serving mainstream markets across Europe, America and Asia for decades.

Key Features & Benefits
Our this product is optimized for complex industrial working conditions, with multiple practical performance advantages to help enterprises improve operational efficiency, reduce equipment loss and meet environmental compliance requirements:
Dissolves Fast & Keeps the Solution Stable: Its water solubility is very high, so the product goes into solution quickly. The brine that forms is clear, with no suspended solids, and nothing settles out of it. During non-stop industrial work, that means steady, repeatable performance.
Stable at High Temperatures: Above 200°C, its physical and chemical properties hold up. The fluid does not fail, and performance does not drop, even under high heat and high pressure. Rough industrial conditions are not a problem for it.
Does Not Corrode & Is Kind to Equipment: The formula contains no chloride. That removes the corrosion risk that old chloride raw materials bring to equipment and infrastructure. Downhole tools, airport facilities, and road infrastructure last longer, so the company spends less on maintenance.
Dual Forms & Flexible Application: You can order it as a solid powder or as a liquid. Either way, it fits the equipment and the process you already run on site. Shale inhibition comes from potassium ion exchange, and that performance is reliable. Wellbore structures stay stable, so drilling continues safely and without trouble.
Eco-Friendly & Compliant: This product breaks down in nature on its own. It also holds PLONOR certification. Chloride-based chemicals of the old type cause ecological damage and pollution. That problem does not come up here. The strict environmental rules used by industry around the world are met as well.

How It Works
The chemical structure is built on the formate ion, so this product takes on several common industry problems at the same time. Wellbore instability is one of them. Equipment corrosion is another. So is failure at low temperatures. Every industrial setting gets its own targeted performance gain:
Shale Stabilization for Drilling: During oil and gas drilling, the potassium ions inside trade places with clay minerals. That ion exchange pulls water out of active shale and firms it up. The wellbore will not cave in, and rock will not swell. Extended-reach drilling then stays stable.
High-Density Solids-Free Brine System: The product dissolves all the way, so no solid bits are left behind. Reservoir and formation damage will not happen. Polymer materials hold up in HPHT conditions because of its thermal stability. They do not break down, which keeps the drilling fluid system stable over the long term.
Efficient Low-Temperature Deicing Mechanism: For deicing on infrastructure and aircraft, the organic salt structure drives the freezing point of water down fast. Heat comes out as it dissolves, and the material spreads well. Ice layers get soaked through and melt in a short time. Metal and concrete also face a lower corrosion risk. Deicing work then stays safe and efficient.
Applications
This product is dense. It resists high heat and causes little corrosion. Safety for the environment is another plus. Those traits explain its wide use. Oil and gas extraction is one field that depends on it. Aviation infrastructure upkeep is another. Industrial processing and catalyst manufacturing also rely on it. The application solutions for them are mature and stable:
Oil & Gas Operations: It goes into solids-free drilling fluids and completion brines for HPHT deep wells. In water-based mud systems, it works as an efficient shale stabilizer. That cuts down formation damage. Drilling also gets safer and more efficient.
Aviation & Infrastructure Deicing: This product fits aircraft deicing and airport runway deicing. Aluminum alloy equipment and carbon-composite brakes take no damage from it. It also does a good job of stopping scaling and corrosion in highway and bridge concrete structures.
Industrial Processing: In chemical synthesis it works as a reducing agent that gets the job done fast. Leather processing relies on it as an auxiliary agent. When concrete is poured in cold weather, it acts as an early-strength accelerator, so the mix sets and hardens sooner.
Catalyst Applications: It works as a main raw material and a chemical intermediate when industrial catalysts are made. Downstream fine chemical plants get a steady supply of raw material with a high purity level.

The product HCO₂K Potassium Formate holds valid KOSHER and HALAL certifications, meeting the raw material standards for food and pharmaceutical auxiliary applications. In addition, it complies with North Sea PLONOR environmental protection specifications for offshore drilling, fully satisfying the strict discharge and environmental assessment requirements of sensitive marine working environments, supporting global offshore project compliance operations.

Packaging Options
We provide differentiated packaging solutions for solid and liquid products, adapting to different transportation, storage and on-site use scenarios of industrial customers:
Solid Form Packaging: The standard pack is a 25kg woven plastic bag. Inside sits a polyethylene liner that keeps moisture out, which stops the product from spoiling. For bulk industrial orders, 1000kg ton-bags are available. They are easy to move with mechanical handling and handy for storage in one place.
Liquid Form Packaging: Our 1000L standard IBC tanks support automatic pumping and exact dosing. Large-volume cross-border orders can also get custom flexibag packaging. That lowers logistics costs and makes transport more efficient.
All our packaging materials meet international shipping standards. They protect product stability on long hauls. Moisture and contamination stay out along the way.

Manufacturing Process
We run a precise neutralization reaction. Formic acid plus potassium hydroxide or potassium carbonate serve as high-purity raw materials for the synthesis. Continuous crystallization gives solid products an even particle size and steady purity.
The production line runs several rounds of precision filtration. That step clears out trace impurities and tiny particles. Every finished batch then goes to the lab. There, technicians check purity levels, measure moisture and screen for impurities. Only then does a batch count as fully compliant with industrial standards.
Supported by 150,000 tons of stable annual production capacity, we can realize continuous and mass production, providing sufficient and stable supply guarantee for global customers' long-term industrial projects.

FAQ
Q: What is the highest drilling fluid density this product can reach?
A: A1: We can build our products into high-purity clear brines. The top density they hit is 1.57 g/cm³ (13.1 lb/gal). That level works well for pressure control in deep oil and gas wells, and in high-pressure ones too.
Q: For shale inhibition, how does it compare with potassium chloride?
A: A2: Shale stabilization and clay dehydration both get much better results with it. The formula has no chloride. So downhole tubulars and drilling equipment do not corrode. Drilling systems can run safely for a long time.
Q: What are the usual storage rules?
A: A3: The product takes in moisture, so keep it in a dry warehouse with good airflow. It must stay sealed and protected from damp. Do not store it together with chemicals it cannot mix with.
Q: Can it handle deicing when temperatures are very low?
A: A4: Yes. The prepared formate solution maintains stable deicing activity at temperatures as low as -50°C, with far better low-temperature resistance than urea and traditional chloride deicing agents.
Q: Can solid and liquid specifications be used interchangeably?
A: A5: Yes. Core performance stays the same across both specs. Use solid products for mechanical spreading. Liquid products are for spray systems and pre-wetting operations. Which one you pick comes down to your on-site equipment and processes.
