MatrEX® Binary Gel FAQ

General Information (The Basics)

What is MatrEX® Binary Gel?
MatrEX® is a "binary" explosive, which means it comes in two parts. Think of it like a two-part epoxy glue. Part A and Part B are liquids that are safe on their own. They only become a powerful explosive when you mix them together through a special nozzle.
Is it dangerous to transport?
Before it is mixed, MatrEX® is classified as a Class 3 Flammable Liquid, similar to how gasoline or paint thinner is categorized. It is not regulated as an explosive (Class 1) during shipping, making it much safer and cheaper to transport than dynamite or C4.
What consistency is it?
When it comes out of the mixer, it feels like thick automotive grease. After a few minutes, it cures (hardens) into a texture like stiff Jello.
Will it leak if I put it in a container upside down?
No. Once the gel cures, it holds its shape perfectly. You can fill a cup, wait a few minutes, turn it upside down, and nothing will drip or run out. This makes it amazing for filling complex shapes or 3D-printed devices.
Can anyone buy this?
No. MatrEX® is a professional-grade energetic material restricted to Military, Law Enforcement, and certified Explosive Ordnance Disposal (EOD) professionals.
Is it like the explosives in movies?
In some ways, yes—it's very powerful. But unlike movie explosives that often look like clay (C4) or liquid, this is a gel. Also, it requires specific initiation (a blasting cap) to go off; you can't just shoot it or light it on fire to make it explode.
How do I clean it up if I spill the unmixed parts?
Since the unmixed parts are just flammable liquids (like solvents), they can be cleaned up using standard absorbent materials (like kitty litter or shop rags) and disposed of according to local hazmat regulations for flammable liquids.
Does it smell?
Nitromethane has a mild, characteristic odor often associated with drag racing fuel or solvents. It is distinct but not overwhelmingly noxious in small quantities.
Can I mix it by hand in a bowl?
Absolutely not. MatrEX® is designed to be mixed only using the static mixing nozzle provided with the cartridge. Mixing by hand is dangerous, unreliable, and violates safety protocols. The nozzle ensures the exact ratio and thorough mixing required for a stable detonation.
What happens if I drop the unmixed cartridge?
Nothing explosive happens. The components are separated and are not shock-sensitive individually. It might make a mess if the plastic breaks, but it won't explode.

Technical Specifications & Data

What is the primary chemical base?
MatrEX® is a Nitromethane-based binary explosive formulation.
What is the Relative Effectiveness (R.E.) Factor?
The R.E. Factor is 1.14. This indicates that MatrEX® generates approximately 14% more blast energy than an equivalent weight of TNT (Trinitrotoluene).
What is the Detonation Velocity (VoD)?
The Detonation Velocity is 6,200 m/s (approx. 20,340 ft/s). This high velocity contributes to its effectiveness in brisance (shattering power) and cutting applications.
What is the density of the mixed product?
The density is 1.09 g/ml.
What is the viscosity of the gel?
The viscosity is approximately 200,000 cP (centipoise). This high viscosity ensures the material does not run or drip, allowing for overhead or vertical application without containment.
What is the Critical Diameter?
  • Un-boosted: 3/8 inch (9.5mm)
  • Boosted: 1/4 inch (6.35mm)
Charges thinner than these dimensions may fail to propagate detonation reliably.
Is MatrEX® Cap Sensitive?
Yes. Once mixed and cured, MatrEX® is shock-sensitive and can be initiated with a standard blasting cap or detonating cord.
What is the N.E.W. for the 50ml cartridge?
51.97 grams (0.11 lbs).
What is the N.E.W. for the 450ml cartridge?
572.62 grams (1.21 lbs).
What is the N.E.W. for the 825ml cartridge?
992.05 grams (2.57 lbs).
What is the shelf life?
MatrEX® has a shelf life of +24 months when stored correctly in its unmixed state. Monthly testing is conducted to verify stability.

Operational Handling & Safety

How long does the gel take to cure?
The gel begins to thicken immediately upon mixing and typically cures to a stable, non-slumping consistency within 5 minutes, depending on ambient temperature.
What is the "working time" after mixing?
Because the curing process is rapid, the "working time" is essentially the time it takes to dispense the cartridge. It is designed for immediate application into the target or device.
How long does the charge remain active?
Once mixed and cured, the charge remains viable and detonable for a minimum of 24 hours.
Is MatrEX® water-resistant?
Yes. As a water-gel based explosive, it has excellent water resistance properties and can be used in damp or wet environments once cured.
Can it be used for shaped charges?
Yes. Its high density, moldability, and high VoD make it excellent for shaped charge applications. It can be injected into 3D-printed or standard liner bodies to create effective penetrators.
Is the gel compatible with 3D-printed polymers?
Extensive material testing has been conducted to ensure compatibility with standard 3D printing materials such as PLA, ABS, and Nylon. The gel does not degrade these casings during the typical operational window.
How does temperature affect curing?
Like most chemical reactions, cold temperatures can slow the curing process, while heat can accelerate it. The gel is formulated to perform within standard operational temperature ranges defined by MIL-STD requirements.
What PPE is required when handling?
Standard PPE for handling flammable industrial chemicals is recommended: safety glasses/goggles and nitrile gloves to prevent skin contact with the unmixed or mixed components.
Why use MatrEX® over C4?
While C4 is an excellent explosive, MatrEX® offers superior logistics (Class 3 transport vs. Class 1), easier moldability into complex geometries (via injection/extrusion), and higher R.E. factor (1.14) in a format that does not require heavy regulatory oversight until mixed.
Can I re-use a nozzle?
No. Once the mixing stops, the gel inside the nozzle will cure and block it. A fresh nozzle must be used for each new application session or if the flow is paused for longer than the cure time.
Does the gel produce fragmentation?
The gel itself does not produce fragmentation. However, whatever container or device it is filled into (steel pipe, 3D printed case with shrapnel) will produce fragmentation upon detonation.
What happens if there is a misfire?
Standard EOD misfire procedures apply. Wait the required soak time (typically 30-60 minutes depending on SOP) before approaching. Since the gel is shock sensitive, it must be handled with the same extreme caution as any live high explosive.
Is MatrEX® suitable for Agile Combat Employment (ACE)?
Yes. MatrEX® was specifically developed with ACE concepts in mind. Its ability to be transported via standard logistics chains (non-hazmat explosive) and mixed on-site allows small teams to deploy with significant explosive capability without the burden of heavy explosive safety arcs during transport.
How do I dispose of expired cartridges?
Unmixed, expired cartridges should be disposed of in accordance with local, state, and federal regulations for flammable liquids and chemical waste. They do not require EOD disposal unless mixed.
