- Product Description
Airport Runway Solid Potassium Formate — High-Purity Non-Chloride Deicer for Aviation Safety
Airport Runway Solid Potassium Formate (HCOOK, CAS No. 590-29-4) is a professional-grade, non-chloride deicing and anti-icing agent engineered for the demanding safety and environmental standards of civil aviation. Manufactured by Shanxi Zhaoyi Chemical Co., Ltd., this product delivers a purity of ≥98%, a freezing point of ≤−35°C, and the snow melts at a rate of 90% in 30 minutes at -20°C. 1.9100 g/cm³ by weight Very good at absorbing water, and it melts easily for mechanical spreading. It is the trusted potassium formate deicer for airport runways and is the choice of large international airports and institutions in cold climates that want to keep their runways in good shape all winter.

What Is Airport Runway Solid Potassium Formate and Why Does It Matter?
Traditional runway deicers, chloride salts and urea, have major problems. Chloride salts can damage carbon brakes, cadmium-plated parts, and aircraft landing gear. Urea adds a lot of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), which makes it hard to follow rules for stormwater discharge.
The product answers both problems. It is a white crystal potassium salt of formic acid and is non-toxic and non-corrosive to aviation infrastructure. It substitutes ecologically dangerous alternatives while providing excellent low temperature performance down to -25°C to -30°C.
This implies less compliance risk, more runway protection and no compromise on airplane safety for airport procurement managers and ground operations teams.
Key Performance Advantages
Non-corrosive to aircraft and structures
Corrosion rate to carbon steel < 0.03 g/m2.h. No corrosion to aviation aluminum alloy materials. This protects landing gear, runway steel structures and terminal infrastructure against long-term harm.
Outstanding low temperature performance
This anti-icing product for airports is a potassium formate with a freezing point of ≤-35°C, therefore it will work in the most severe winter circumstances. It’s especially well-suited for extreme cold areas at airports where traditional glycol-based fluids lose effectiveness.
Rapid snow-melting speed
Within 30 minutes at -20°C, the product melts at least 90% of the snow. This quick activation time is very important for keeping safe flight schedules and minimising runway downtime.
Good movement — no caking
The solid granule form maintains excellent flowability, making it compatible with large-scale mechanical spreaders. Operational efficiency is maintained even during heavy snowfall events needing quick deployment.
Environmentally responsible
With a significantly lower BOD and COD profile compared to urea, it supports compliance with modern stormwater runoff regulations — an increasingly important factor for airport environmental audits.
Core Application Scenarios
The primary use case for Airport Runway Solid Potassium Formate is deicing and anti-icing of airport runways, taxiways, and aprons during winter operations. It is especially suitable for:
- Large international airports with strict environmental and safety compliance requirements
- Airports in severe cold regions where temperatures drop below −20°C regularly
- Airport bridges, access passages, and surrounding infrastructure requiring anti-icing treatment
Beyond aviation, the product's high-purity potassium formate formulation also finds application in oilfield drilling fluids, the leather industry as a masking acid, print and dyeing as a reducing agent, and in cement early-strength and leaf fertilizer applications.

FAQ
Q: Does this product meet international civil aviation organization standards?
A: Yes. The product is made to meet international standards for deicing in civil aviation. For example, it meets the requirements of SAE AMS 1431 for solid runway deicers. If you ask, you can get supporting documents and test results from a third party.
Q: What is the corrosion resistance of aircraft parts?
A: As for A, the rate of rust to carbon steel is 0.033 g/m³h, and the product doesn't corrode aircraft aluminium alloys. This means it is safe to use near brakes, landing gear and other sensitive parts of an aeroplane.
Q: How well does it work when it's very cold, like −35°C?
A: This potassium formate deicer for airport runways doesn't freeze at temperatures below 35°C, so it can still be used in very cold weather. It works especially well for airports in places with very cold weather.
Q: Can you offer a lot of items when demand is high in the winter?
A: Yes. We can meet your needs for big quantities and bulk purchases because we can produce 150,000 tonnes per year and have stable upstream supply chains for raw materials. Most of the time, emergency stock orders can be made within 24 hours.
Q: Is there expert help after I buy something?
A: Sure thing. We offer technical help, application guidance, and suggestions for improving usage 24 hours a day, seven days a week. Our team can help with questions about on-site operations, motorised spreading factors, and dose suggestions.
Q: What proof can you give to make sure airport procurement rules are followed?
A: We offer COAs, MSDSs, conformity certificates, ISO certification documents, and test reports in multiple languages. We can also help customers who have strict requirements for supply chain verification with factory audits.
