Provided is a method for preparing a PSA composition for protecting Low-E glass plates from degradation and corrosion. A PSA composition preparation method is provided for Low-E glass plate protection. The method comprises a step of obtaining an aqueous liquid, and a step of obtaining a polymer-containing liquid comprising the aqueous liquid and a polymer. Here, the aqueous liquid satisfies at least (a) having an electrical conductivity below 300 μS/cm or (b) having a chloride ion concentration below 35 μg/mL.

Provided is a Low-E glass plate protective sheet that can have protective properties for a Low-E glass plate as an object to be protected and can maintain good removability while preventing or inhibiting surface contamination of the object to be protected even when prolongedly adhered thereto. The Low-E glass plate protective sheet is provided. The protective sheet has a PSA layer. The PSA layer comprises at least 95% base polymer by weight.

The present invention relates to a vulcanizable elastomeric composition comprising a secondary accelerator that may be used in combination with sulphenamide alone, completely avoiding the use of a guanidine. Moreover, said accelerator promotes dispersion of the silica in the compound and migrates with difficulty in the elastomeric composition itself. The invention also relates to the use of a vulcanization accelerator for said elastomeric composition, to the associated vulcanization process and to a tyre comprising same.
