What Is AF-31?
AF-31 is a next-generation fire protection solution designed to meet the evolving demands of a world shifting toward electric mobility, sustainable infrastructure, and wildfire defense. Unlike traditional suppression systems that rely on toxic chemicals or leave behind damaging residues, AF-31 is a clean, water-based agent derived from food-safe components. It works by penetrating surfaces, disrupting combustion chemistry, and forming a barrier that prevents oxygen from fueling the fire. This makes it uniquely effective not only in extinguishing flames but in preventing reignition — a critical feature in lithium-ion battery scenarios. Backed by third-party testing, certified for environmental safety, and trusted in billions of dollars’ worth of development projects, AF-31 represents a technological and ecological leap forward in fire suppression and prevention.
1
Eco-Safe Chemistry |
AF-31 contains no PFAS or “forever chemicals” and is certified UL Greenguard Gold, ensuring it’s safe for humans, pets, and the environment.
2
Non-Corrosive, Water-Based Formula
Safe to use around electronics, equipment, and construction materials. Leaves no damaging residue behind after deployment.
3
Reignition Prevention
Unlike foam or blankets that only suppress the flame, AF-31 forms a persistent barrier that stops fires from reigniting — even after thermal runaway.
4
Flexible Deployment
Can be applied by certified spray teams, integrated into pre-treatment protocols, or used in emergencies as a direct suppressant.
5
Proven Track Record
Deployed across over $15 billion in development projects without a complete structural fire loss. Used by major builders, fire authorities, and municipalities.
Performance & Safety Assurance
AF-31 has been tested under extreme thermal conditions — maintaining suppression efficacy at temperatures exceeding 2500°C. Its chemical stability, non-toxicity, and water-based formulation make it safe for use in sensitive environments such as residential buildings, EVs, industrial sites, and public infrastructure. Unlike conventional foams or powders, AF-31 penetrates materials, prevents reignition, and leaves no harmful residue — ensuring continued protection long after the fire is extinguished.

QAI Laboratories
Independent third-party fire testing
Stops thermal runaway events at the source and prevents reignition. Used in electric vehicles, energy storage systems, scooters, telecom, and battery manufacturing.
Our fire inhibitor is professionally applied as a pre-treatment to homes, critical infrastructure, public buildings, and wildfire-prone zones—creating a long-lasting barrier against ignition. In addition to protecting properties, we strategically safeguard evacuation routes and community corridors to ensure safe passage during fire events. This proactive approach not only reduces wildfire impact but also mitigates insurance exposure and enhances public safety during peak fire seasons.
Why It Works
AF-31 doesn’t just put out flames — it interrupts the chemical chain reaction that makes modern fires so difficult to stop. From lithium-ion cells to wood-framed structures, AF-31 adapts to multiple fire classes without needing additives, extenders, or formulation changes.
Disrupts Thermal Runaway
Stops the self-sustaining heat cycle that accelerates fire growth—critical in halting lithium-ion battery failures and other high-intensity fire scenarios.
Neutralizes Fuel Sources
Penetrates and treats combustible materials at the source, disrupting the fire’s ability to ignite or spread by removing heat transfer and ignition potential.
Versatile Across All Surfaces and Environments
Engineered for use on wood, insulation, metal, lithium batteries, and composite materials—while also effective on vegetation, open spaces, and wildland areas. AF-31 delivers clean, corrosion-free protection across manmade built and natural environments.
Enduring Fire Resistance
Once applied, AF-31 remains effective through extreme heat, weather exposure, and time—delivering reliable, long-term protection when and where it’s needed most.
