Fibrin is the key component in secondary hemostasis that binds the platelets into a solid plug. When activated, fibrinogen is converted into fibrin, which creates a mesh-like network that reinforces the primary plug created by platelets, resulting in a stable blood clot. Thrombin plays a role in converting fibrinogen to fibrin but alone cannot bind the platelets into a solid plug. Tissue factor and plasminogen are not directly involved in binding platelets.
