Abstract:
Hot-melt pressure-sensitive adhesive based one or more non-thermoplastic elastomers, comprisingat least 100 parts by mass of a natural rubber; from 1 to 100 parts by mass of one or more tackifying resins selected from the group consisting of a hydrogenated resin and an aromatic-modified hydrocarbon resin; from 1 to 100 parts by mass of one or more reactive phenolic resins, for the chemical/thermal crosslinking of the hot-melt pressure-sensitive adhesive, wherein the one or more reactive phenolic resins are selected from the group consisting of an octylphenol-formaldehyde resin having a methylol content of form 6 to 9% by weight and an octylphenol-formaldehyde resin having a methylol content of form 9 to 13% weight and a bromine content of 6 to 9% by weight; optionally from 1 to 100 parts by mass of crosslinking accelerator substances.
