Product information
SEAL Hemostatic Spray PRO by BC3 Technologies is the first and only FDA-cleared chitosan aerosol spray for emergency bleeding control — a Rx-labeled, professional-use hemostatic that deploys as a dry-powder aerosol in under 5 seconds to form a rapid physical barrier over wounds. It is the only hemostatic on the market combining chitosan's proven muco-adhesive mechanism with aerosol delivery, validated under MIL-STD-810H and tested equivalent to Celox in FDA 510(k) clearance (K210751). Made in the USA.

Product Overview
SEAL Hemostatic Spray PRO represents an entirely new form factor in hemorrhage control — the world's first FDA-cleared aerosol hemostatic for emergency bleeding. BC3 Technologies, founded in Baltimore in 2018, spent approximately 12 years developing the aerosol chitosan delivery platform before achieving FDA 510(k) clearance in 2023, with a U.S. patent awarded for the formulation and delivery system in April 2025. The PRO version carries a Prescription (Rx) label intended for EMS, hospital, tactical medical, law enforcement, and fire department use.
The mechanism is chitosan-based — the same class of hemostatic agent as Celox and ChitoGauze — but delivered as a dry-powder aerosol. When SEAL contacts blood at the wound site, the chitosan particles interact with red blood cell membranes via electrostatic muco-adhesion, forming a physical barrier that rapidly seals the wound. The cold propellant in the pressurized can also acts as a mild vasoconstrictor on contact, providing an additional mechanism to slow blood flow during the initial application. The full can empties in under 5 seconds when sprayed; the hemostatic barrier begins forming within approximately 30 seconds of application.
Critically, SEAL is blood-activated only — it does not react with water, rain, or sweat. This means it maintains reliable performance in maritime operations, wet environments, rain, and situations where the casualty has been immersed. The spray has been validated under MIL-STD-810H environmental testing, maintaining reliable spray performance from –24°F to 160°F. In the rat liver model used for FDA clearance testing, SEAL showed biological safety and was assessed as an efficient hemostatic product with non-inferiority to Celox (its predicate device). It does not generate heat, does not cause systemic clot formation (reacts locally at the wound site only), and does not trigger shellfish allergies (allergens are removed during chitosan purification).
SEAL PRO excels in scenarios where traditional wound packing is difficult or time-consuming: irregular wounds, shrapnel injuries, graze wounds, neck wounds (where packing is contraindicated), multiple simultaneous casualties, and wounds that are difficult to access or pack under fire. It is particularly valuable as an initial intervention — spray to establish a physical barrier, apply pressure, then proceed with standard TCCC hemorrhage control protocols. SEAL can be used in conjunction with QuikClot Combat Gauze and other hemostatic gauze products — these are complementary tools, not mutually exclusive.
How to Use
- Shake the can before use.
- Hold the can 6–10 inches from the wound surface.
- Spray directly onto the bleeding wound for approximately 5 seconds.
- Apply direct pressure over the sprayed area while the chitosan barrier forms (approximately 30 seconds).
- Secure with a pressure bandage.
- For deeper wounds requiring packing, apply SEAL first to establish a surface barrier, then pack with hemostatic gauze — the packing action drives the spray deeper into the wound track.
- Remove with saline rinse at definitive care.
Where SEAL Fits in the Kit
SEAL does not replace tourniquets, wound packing, or pressure dressings — standard TCCC hemorrhage control still applies. Think of SEAL as a rapid-deployment initial intervention that buys time to apply additional interventions. It is not a primary treatment for deep cavitary wounds, junctional hemorrhage, or wounds requiring direct digital pressure to the bleeding vessel. For those applications, hemostatic gauze and tourniquets remain the standard. SEAL's unique advantage is speed and accessibility — wounds that would take 30+ seconds to pack can have a hemostatic barrier established in under 5 seconds.

SEAL Hemostatic Spray
Is SEAL a single-use product?
Yes. Each SEAL canister is designed for single-use application during emergency bleeding control.
Can I spray it more than once?
SEAL releases all contents in one use. For demonstrations or training, we offer trainer cans and videos.
How do I remove SEAL from the wound?
To remove SEAL, rinse the area with sterile water or saline and gently wipe with sterile gauze.
Is this just some fancy Crazy Glue as others claim?
No, anyone who makes that claim is clearly not familiar with the product. This is a spray delivery system for Chitosan, a widely used, heavily studied, extremely effective hemostatic agent.
What does SEAL feel like after spraying?
It forms a soft barrier similar in texture to a scab, sealing the wound quickly.
How long can it stay on the wound?
SEAL can remain in place for up to 24 hours before removal is recommended.
Is SEAL safe for people with shellfish allergies?
Yes. SEAL uses medical-grade chitosan that is purified to remove allergenic proteins. It passes all biocompatibility standards.
Are there any known risk or side effect?
When used as instructed, SEAL poses no risk of burns, tissue damage, or adverse reactions. No complications have been reported.
Does SEAL replace tourniquets?
No. SEAL does not replace tourniquets, but it may reduce the need for one in some situations. It is most effective on accessible external bleeding.
How do I properly use SEAL spray?
Firstly, do not insert the spray nozzle directly into wounds. Spray directly onto the surface while applying pressure.
SEAL is not a magic spray, for instances of several bleeding, you should follow up with direct pressure and subsequent bandaging.
SEAL is not recommended for use in the eyes or for treating sucking chest wounds.
