Understanding Flame-Resistant Materials and Coatings
When a fire breaks out, seconds matter—and the right flame-resistant materials and coatings can be the barrier that protects passengers, cargo, and critical systems. Flame-resistant materials have three key functions:
- They limit oxygen access at the material surface.
- They form insulating char layers to slow heat transfer.
- And in some cases, they self-extinguish once a flame source is removed.
Some achieve this through their base chemistry, while others rely on advanced coatings that create a protective barrier when exposed to high temperatures. Either way, the goal is the same—extend critical response time and contain a fire before it can grow.
Key Fire Safety Regulations for Aerospace Applications
Fire testing is fundamental in aerospace manufacturing. There are three core tests across the aviation industry to evaluate flame-resistant materials and coatings.
1. Vertical Burn Test (FAR 25.853(a))
This is often the first line of defense. In the vertical burn test, a material sample is exposed to a direct flame and evaluators measure how far the flame spreads in a given amount of time for a set period, and evaluators measure how quickly the flame spreads—if at all. Materials should either self-extinguish quickly or severely limit the flame’s upward movement.
Why it matters: In the event of a fire, fast flame spread along cabin walls, ceilings, or seating must be prevented to allow passengers critical time to evacuate.
2. Radiant Panel Test (FAR 25.856(a))
The radiant panel test evaluates flame spread when exposed to radiant heat and a flaming ignition source to simulate conditions of the early stages of a fire in adjacent areas and measures how easily materials ignite and contribute to fire growth when exposed to radiant heat without direct flame contact. This is especially important for materials used in aircraft insulation systems, panels, and hidden spaces.
Why it matters: Fires rarely start with an open flame in real-world scenarios. Testing resistance to radiant and adjacent heat ensures that hidden ignition sources don’t silently escalate into major threats.
3. Flame Penetration Resistance (FAR 25.856(b))
Reserved for thermal/acoustic insulation materials, the flame penetration resistance test simulates exposure to extremely high temperatures (over 1,800°F). The material must resist penetration by both flames and intense heat long enough to maintain structural integrity.
Why it matters: In a post-crash or in-flight fire situation, insulation materials must slow fire spread into fuselage structures, providing passengers and crew additional protection.
Duracote’s Solutions for Fire Safety
Meeting modern transportation and aerospace fire safety regulations means more than putting flame-resistant materials in place—you need to have the right materials for the right risks.
That’s where our expertise can help. Every product we design (including custom product solutions) solves real-world problems manufacturers face when pushing for higher standards of fire safety compliance.
Layers of Protection: Dura-Trim®
Designed to help interiors withstand open flame and intense radiant heat, Dura-Trim® materials are flexible, lightweight, and tested to meet critical aerospace standards like FAR 25.853(a) and 25.856(ab). They’re used in everything from commercial aircraft cabins to military transport vehicles, spaces where every second in a fire situation matters.
The secret is a layered structure: durable surfaces combined with fiberglass reinforcements and specialized flame-retardant coatings to control burn behavior without adding unnecessary weight. That’s a huge advantage for designers who need both protection and performance.
Next-Generation Fire Safety: Frontier® FR
Sometimes, it’s not enough for a material to resist fire, it has to do more. That’s the thinking behind Frontier® FR, a new generation of advanced materials developed by Duracote to meet FAR 25.853(a), 25.856(a), and FAR 25.856(b) standards. These systems offer superior flame resistance, yes—but they also reduce noise and control static buildup.
In aerospace and transportation, where weight, safety, and comfort all collide, a material like Frontier® FR offers manufacturers a smarter path forward: fewer layers, lighter structures, and uncompromised fire protection. It’s one solution that solves multiple engineering headaches at once.
Aqueous Coatings: Eco-Friendly Protection
For manufacturers working on upgrades, retrofits, or cost-sensitive builds, replacing every component isn’t always realistic. That’s where aqueous flame-retardant coatings offer a powerful advantage.
Duracote’s water-based solutions can boost fire resistance on existing textiles, composites, and other materials, helping projects meet fire codes without major redesigns. Plus, being water-based helps lower VOC emissions during production, making them a smarter option for environmentally conscious manufacturers.
