Provided is a tire puncture sealant having excellent puncture seal durability. The present disclosure relates to a puncture sealant containing at least one natural rubber latex, at least one antioxidant, at least one antifreezing agent, and at least one selected from the group consisting of protease inhibitors and phosphatase inhibitors.

An assembly of a pneumatic tire and of a wheel, the pneumatic tire (10) being fitted to the wheel. The assembly comprises first and second self-sealing products housed in the internal volume (V) of the pneumatic tire (10). The first self-sealing product, referred to as solid self-sealing product (OS), covers a predetermined part of the internal surface of the pneumatic tire (10). The relative position of this predetermined part in the pneumatic tire (10) does not substantially vary under the effect of gravity. The second self-sealing product, referred to as liquid self-sealing product (OL), is in the liquid form.

The invention relates to a distributor device (1) for generating an aerosol (8) comprising both gas and sealant, wherein the distributor device has at least one gas connector (2) for connection to at least one compressed-air source (11), at least one sealant connector (3) for connection to at least one sealant container (12), and one or more than one connecting element (4) for connection to a pneumatic vehicle tire (16), characterized in that the distributor device has a metering unit (5) for metering the sealant quantity fed to the distributor device. The invention also relates to a system for sealing and inflating pneumatic vehicle tires, and to a method for sealing pneumatic vehicle tires or inflatable technical articles, and to the use of a dosing unit for generating an aerosol.

A self-sealing composition is based on at least: one thermoplastic styrene elastomer; one polyolefin having a number-average molar mass Mn ranging from more than 550 000 to 5 000 000 g/mol; and at least 140 phr of an extender oil.

An apparatus and method for a cap for dispensing sealant from a pressurized bottle, to a tire stem valve, includes a cap body, a hose positioned within the cap body where the hose is configured to wrap around at least one storage groove inside a circumference of the cap. The at least one storage groove is helical and the cap also includes a diameter of the cap body where the diameter includes a length of the hose wrapped around the at least one storage groove.

Various embodiments of the present disclosure relate to a coagulatable mixture. The coagulatable mixture includes a solvent component; an antifreeze component; a latex component; and a solid filler component.

A mixing device for mixing a puncture repair liquid and compressed air includes a mixing chamber, a first inlet for supplying the compressed air to the mixing chamber, a second inlet for supplying the puncture repair liquid to the mixing chamber, and an outlet for discharging a mixture of the puncture repair liquid and the compressed air from the mixing chamber. The mixing chamber includes a deposition section for depositing agglomerates contained in the puncture repair liquid. The deposition section is provided between the second inlet and the outlet.

A mixing device for mixing a puncture repair liquid and compressed air includes a mixing chamber, a first inlet for supplying the compressed air in a first flow direction to the mixing chamber, a second inlet for supplying the puncture repair liquid to the mixing chamber, and an outlet for discharging a mixture of the puncture repair liquid and the compressed air from the mixing chamber. The outlet discharges the mixture in a second flow direction at a position displaced from a virtual line extending from the first inlet in the first flow direction.

Disclosed herein are a sealant composition for use with tires, a tire having at least one component with at least one surface at least partially coated with the sealant composition, and related methods for applying the sealant composition to tires. The sealant composition comprises biorubber and a softener comprising at least one of plant oil or plant resin and has a non-petroleum content of at least 70% by weight.

The tire comprises a tread (14) comprising a deeply cut rib (68, 70) and a slightly cut rib (62, 64, 66), and a layer of a self-sealing product (80) comprising: a portion (90″, 92″) extending in line with the deeply cut rib (68, 70) and having an average thickness Ec > 0 of self-sealing product, and a portion (100′, 102′, 104′) extending in line with the slightly cut rib (62, 64, 66) and having an average thickness Eb ≥ 0 of self-sealing product such that Eb <Ec.
