The invention relates to a method for the production of a tire sealant (C) with a polymeric base. A highly viscous first sealant component (A) (including a natural rubber component that is undiluted or diluted with at least one additional natural rubber component and mixture ingredients that are free of a solvent and an activator) is mixed with at least one second sealant component (B) (comprising a separately produced medium with low viscosity containing at least one activator), to combine to the tire sealant (C), wherein a cross linking occurs associated with the subsequent application of the tire sealant (C) to the inside of the tire. Appropriate method steps are disclosed.

Method of making a solvent-free polymer-based tire sealant

A self-sealing pneumatic tire has a sealing band () applied adheringly in the circumferential direction on the inner side of the tire and radially within the tread. A sealant () is applied to a carrier material (). The carrier material () of the sealing band () is a foil on which the sealant () has been applied. The sealant, because of its intrinsic stickiness, adheres both to the carrier material () and to the inner side of the tire.
