Abstract[English]
An object of the present invention is to provide an acrylic resin-containing adhesive composition having high EMI shielding performance, wherein the composition provides an EMI shielding cured product that has high impact resistant and is sufficiently cured at a low temperature, and when the composition is applied to a metal surface, the adhesion surface has high pull strength. The present invention relates to an EMI shielding adhesive composition comprising (a) a conductive filler, (b) a (meth)acrylic resin, (c) a tackifier, (d) a bismaleimide and (e) a radical initiator.[French]
Un objet de la présente invention est de fournir une composition adhésive contenant une résine acrylique ayant une performance de blindage EMI élevée, la composition fournissant un produit durci de blindage EMI qui a une résistance aux chocs élevée et est suffisamment durci à basse température, et lorsque la composition est appliquée sur une surface métallique, la surface d'adhérence a une résistance à la traction élevée. La présente invention concerne une composition adhésive de blindage EMI comprenant (a) une charge conductrice, (b) une résine (méth)acrylique, (c) un tackifiant, (d) un bismaléimide et (e) un initiateur radicalaire.
