Abstract
Official abstract text for this publication.
A method for reducing the stickiness on the surface exposed to the air of a sealant layer applied on an inner cavity of a tyre. The method establishes that the surface exposed to the air of the sealant layer is subject to a UV radiation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for the application of a sealant layer in a tire comprising a deposition step, in which a vulcanized sealant layer having a stickiness is deposited on a free surface of an inner liner layer facing an inner cavity of the tire; and a step of reduction of the stickiness, in which a surface exposed to the air of said sealant layer deposited on said inner liner layer is subject to the direct action of a UV radiation. 2. A method according to claim 1 , characterized in that said UV radiation has a wavelength range ranging from 200 to 400 nm. 3. A method according to claim 1 , characterized in that said UV radiation has a radiant exitance ranging from 250 W/m 2 to 1500 W/m 2 . 4. A method according to claim 3 , characterized in that said UV radiation has a radiant exitance ranging from 500 W/m 2 to 1000 W/m 2 . 5. A method according to claim 1 , characterized in that said surface exposed to the air is subject to a UV radiation for an amount of time ranging from 5 min to 15 min.
