The sealant can includes a body in which sealant is received, and the cap is connected on an open end of the body. The cap includes an air inflow tube and a sealant supply tube), and the cap is engaged on the first coupling orifice or the second coupling orifice. The at least one delivery hose includes a first connector and a second connector connected with two components, thus inflating and repairing the broken tire diversely.

Disclosed herein are kits for use in adding degradable foam to a tire, methods for preparing a degradable foam-containing tire, tires containing degradable foam, and methods for degrading the degradable foam in tires containing degradable foam. The degradable foam comprises a combination of (i) at least one di- or polyisocyanate, (ii) at least one polysiloxane diol, at least one polysiloxane diamine, or a combination thereof, and (iii) optionally at least one polyol.

A tire repair device with an inflation compressor and a sealant material canister, and method of operation. A pressure gauge determines a tire inflation pressure, and a controller identities a completion of a sealant injection upon a pressure drop measured at the pressure gauge. The controller is configured to automatically shut off the inflation compressor when a tire pressure meets a predetermined inflation value after the pressure drop.

A method for repairing a leak caused by a hole (3) at the bottom of a container (I) with liquid contents (2), comprising a reversible sealing of the leak in which: -a sealing mixture (5) is poured into the liquid contents in the vicinity of the hole, the sealing mixture (5) comprising a sealing product (7) and solid fillers (8) mixed into the sealing product (7), the sealing product (7) having a density greater than those of the liquid contents and the fillers, and the capability to solidify within the liquid contents (2), -the sealing mixture (5) spreads over the bottom (4) of the container (I) and reaches the hole (3), -fillers (8) filling the hole (3) and enabling the sealing product (7) to solidify over the hole, forming a peelable sealing layer that can then be removed after the container is emptied, before the leak is ultimately repaired.

The invention relates to a device (1) for transporting compressed air and/or sealant into a pneumatic vehicle tire, comprising at least one gas connection (3) for connecting to at least one compressed-air source (24), at least one sealant connection (2) for connecting to at least one sealant container (6), at least two channels, wherein a first channel is a sealant transport channel (4) for transporting a sealant dispersion from the sealant connection into a pneumatic vehicle tire and a second channel is a compressed-air transport channel (5) for transporting compressed air to the sealant connection or to the sealant transport channel, wherein the sealant dispersion comprises sealant particles and compressed air as dispersion matrix, characterized in that the device has a movable switchover element (7), wherein the movable switchover element can be moved in the direction of the sealant connection by means of a compressed-air flow coming from the gas connection and has a severing portion (8) for severing a seal. The invention also relates to a portable/transportable system (38) and to corresponding methods and corresponding uses.

A method and system for applying a sealing agent to a surface (2) of an inner cavity (3) of a pneumatic tyre; the method provides for detecting the weight of the pneumatic tyre (4) before and after the application of the sealing agent to the surface (2); calculating the difference between the quantity of sealing agent applied to the surface (2) and a reference quantity of sealing agent, storing said difference within a short-term memory buffer (24) and a long-term memory buffer (26); determining a short-term compensation factor (K.sub.ST) and a long-term compensation factor (K.sub.LT) and calculating a correction factor (K.sub.EA) using alternately the short-term compensation factor (K.sub.ST) or else the long-term compensation factor (K.sub.LT); and using said correction factor (K.sub.EA) to actuate an applicator device (7) during the subsequent step of applying the strip of sealing agent to the surface (2).

A method of preparing a self-healing composition is disclosed, the method including following steps. An isocyanate solution, a dihydric alcohol solution, and a metal salt solution are provided. The dihydric alcohol has heterocyclic structures. The isocyanate solution and the dihydric alcohol solution are mixed, causing the isocyanate and the dihydric alcohol polymerize to form a polymer precursor. The polymer precursor includes a hard segment and a soft segment. The hard segment includes urethane groups, the soft segment includes heterocyclic structures. The polymer precursor and the metal salt solution are mixed, causing the heterocyclic structures and metal ions to undergo a chelation reaction to form a coordination complex, thereby forming the self-healing composition. A self-healing composition prepared by the method, and self-healing film using the self-healing composition are also disclosed.

A method for repairing composite components includes installing a plug within a feature defined by a composite component, with the plug being formed from one or more neutral materials. Furthermore, the method includes infiltrating the composite component with an infiltrant to densify a repair region of the composite component, with the plug blocking a flow of the infiltrant into the feature. Moreover, after infiltrating the composite component, the method includes removing the plug from the feature.

A method for sealing and inflating inflatable articles, in particular for sealing and inflating motor vehicle tires, wherein, by means of a compressor which is driven preferably by means of an electric motor, a sealing and pumping pressure is generated, wherein, by means of the sealing and pumping pressure, via a valve and distributor device for sealant and compressed gas and via compressed-air and sealant hoses between valve and distributor device and an entry valve or an inlet nozzle of the inflatable article, a sealant situated in a sealant vessel connected to the valve and distributor device is conveyed into the inflatable article and, at the same time, the inflatable article is inflated to a predefined operating pressure, wherein, by configuration of the corresponding parameters, of the sealant and of the device, in or downstream of the entry valve/the inlet nozzle, the sealant is at least partially atomized to form an aerosol by virtue of the sealant or the sealant-air mixture being converted, in the entry valve or in the inlet nozzle, into a turbulent flow with a Reynolds number Re≥22300.
