How FXN-M200 microcapsule fire suppression technology works
FXN-M200 is a heat-activated microencapsulated fire suppression additive for industrial coatings and compatible material systems. A heat-responsive thermoset polymer shell contains FK-5-1-12 clean agent and releases it locally when sufficient heat causes the capsule to rupture.
For formulators, manufacturers, OEMs and R&D teams.

01 / Heat-triggered release
From encapsulated agent to a local response
The microcapsule supplies the heat-responsive mechanism. The surrounding material and application determine how effectively that mechanism performs.
Agent contained
The shell holds FK-5-1-12 inside each capsule during proper storage, handling and compatible processing. FXN-M200 is supplied as a free-flowing solid powder.
Shell activates
Sufficient heat ruptures the shell. The current FXN-M200 TDS reports approximately 140°C (284°F), verified by thermogravimetric analysis (TGA). This is not a universal activation temperature for every FireXNull product.
Agent releases locally
Released FK-5-1-12 vapor absorbs heat and cools the ignition zone to help suppress combustion. The capsule response requires no external power, sensors or manual trigger.

| Property | Reference value | What it means for evaluation |
|---|---|---|
| Supplied form | Free-flowing microencapsulated powder | Industrial and professional incorporation into compatible host materials. |
| Active agent / shell | FK-5-1-12 / thermoset polymer shell | Clean-agent core in a heat-responsive thermoset polymer shell. Composition details provided in the current TDS. |
| Median particle size (D50) | 200 ± 20 µm | Laser diffraction reference method. Consider dispersion and final film design. |
| Activation / shell rupture | Approximately 140°C (284°F) | TGA-verified, in-product reference. Values can vary with batch and test conditions. |
| Loading | Formulation-dependent | Starting guidance provided in the current TDS. Final loading is set by the formulator's lab for the target host system. |
| Sealed storage / shelf life | 10–30°C (50–86°F) / 12 months | From manufacture, in original sealed packaging under specified storage conditions. |
| Service life after incorporation | Application-specific; not established universally | Validate durability and performance in the final cured host system. |
FXN-M200 is a component additive supplied for integration into compatible host materials. Fire suppression performance depends on the final cured system and must be validated by the formulator. FXN-M200 is not a replacement for code-required fire protection systems.

03 / Material integration
Build the evaluation around your host material
FXN-M200 is intended for evaluation in protective coatings, polymer matrices, composites, adhesives and sealants. Candidate systems include selected epoxy, polyurethane, polyaspartic and acrylic formulations. Compatibility must be demonstrated for your specific formulation.
Protect capsule integrity during processing
- Complete high-energy dispersion before adding FXN-M200.
- Add the powder late in the process to the fully combined binder system.
- Use controlled low-energy dispersion. Avoid grinding, milling, crushing and high-shear mixing.
- Screen viscosity, settling, pot life, adhesion, film integrity and capsule damage before scaling up.
Validate the complete system
Fire performance depends on loading, film thickness, substrate, enclosure geometry, ventilation, fire source and test method. Evaluate the finished material under conditions representative of its intended use.
- Formulation: dispersion, compatibility and capsule survival.
- Application: layer design, adhesion and material uniformity.
- Performance: relevant fire exposure and end-use conditions.
- Durability: aging, environment and service-life requirements.

Is FXN-M200 the same as a finished sticker, rope or tape?
No. FXN-M200 is supplied as an additive powder for incorporation by industrial and professional formulators. Finished products have their own construction, installation requirements and specifications. Do not transfer their activation values or test results to an FXN-M200 formulation.
Can I add FXN-M200 to any paint or resin?
Compatibility is not universal. Binder chemistry, solvents, processing energy, cure conditions and film design can affect capsule integrity and final performance. Begin with a small compatibility screen and validate the intended host system.
How is the loading level determined?
Starting guidance is provided in the current TDS. Final loading is set by the formulator's lab for the target host system. Fire suppression performance depends on the final cured system and must be validated by the formulator.
Does the 12-month shelf life describe the cured coating?
No. It describes the powder in original sealed packaging under specified storage conditions. Service life in a cured coating or other host material is application-specific and must be validated by the integrating manufacturer.
Which documents should my technical team request?
Request the current FXN-M200 technical data sheet and safety data sheet, then discuss your binder, processing method, substrate, environment and evaluation goals with FireXNull. Use the current document revision when planning tests.
