Title
(EN) PRESSURE-SENSITIVE ADHESIVE AND PRESSURE-SENSITIVE ADHESIVE TAPE
(FR) ADHÉSIF SENSIBLE À LA PRESSION ET RUBAN AUTOADHÉSIF
Abstract
(EN)
A pressure-sensitive adhesive having high self-adhesive strength while suppressing adhesiveness to other material surfaces, and a pressure-sensitive adhesive tape including such pressure-sensitive adhesive. The pressure-sensitive adhesive according to an embodiment of the present disclosure includes a styrene-isoprene block copolymer, an adhesion-imparting agent containing an aliphatic compound, and a terpene phenol resin, and contains 2.0 parts by mass to 10 parts by mass of a terpene phenol resin based on 100 parts by mass of the pressure-sensitive adhesive.
(FR)
L'invention concerne un adhésif sensible à la pression ayant une force d'auto-adhésion élevée tout en offrant une adhésivité limitée vis-à-vis d'autres surfaces de matériau, et un ruban autoadhésif comprenant un tel adhésif sensible à la pression. L'adhésif sensible à la pression selon un mode de réalisation de la présente invention comprend un copolymère séquencé styrène-isoprène, un agent d'adhésion contenant un composé aliphatique et une résine terpène phénolique, et contient 2,0 parties en masse à 10 parties en masse d'une résine terpène phénolique sur la base de 100 parties en masse de l'adhésif sensible à la pression.
