Powder + Pressure = Instant Scab.
WoundSeal Powder is composed of a hydrophilic, or water-loving, polymer and potassium ferrate.
When the powder is poured onto a bleeding wound, the hydrophilic polymer instantly dehydrates the blood by absorbing only the plasma or liquid portion of the blood stacking the blood solids beneath the powder. Simultaneously, the potassium ferrate dissolves, releasing iron that agglomerates (binds together) the blood solids to create an occlusive seal.
As manual pressure is applied to the powder, the seal is pushed into contact with the wound. The natural glue-like nature of drying blood adheres the seal to the wound and surrounding skin. The occlusive seal, that has formed in seconds, stops further bleeding or oozing. Blood solids continue to stack beneath the seal, strengthening it. The natural clotting process proceeds below the seal.
