Use of reactive phenolic resins in the preparation of highly viscous self-adhesive compositions

   
   

Hot-melt pressure-sensitive adhesive based one or more non-thermoplastic elastomers, at least comprising 100 parts by mass of the non-thermoplastic elastomer(s), from 1 to 200 parts by mass of one or more tackifying resins, from 1 to 100 parts by mass of one or more reactive phenolic resins whose methylol content is from 1 to 20% by weight, based on the reactive phenolic resin, from 1 to 100 parts by mass of accelerator substances.

Quente-derreta o adesivo pressure-sensitive baseou um ou mais elastomers non-non-thermoplastic, compreendendo ao menos 100 porções pela massa do elastomer(s) non-non-thermoplastic, 1 a 200 porções pela massa de uma ou mais resinas tackifying, 1 a 100 porções por uma massa de um ou mais resina phenolic reactive cujo o índice do methylol é 1 a 20% pelo peso, baseado na resina phenolic reactive, 1 a 100 porções pela massa de substâncias do accelerator.
