Title
(EN) MULTI-PHASE ADHESIVE ARTICLES AND METHODS THEREOF
(FR) ARTICLES ADHÉSIFS À PHASES MULTIPLES ET PROCÉDÉS ASSOCIÉS
Abstract
(EN)
Provided are adhesive articles and related methods of making and use. The adhesive article includes one or more patterned adhesive layers comprising compositionally and spatially distinct adhesives that are laterally disposed relative to each other. The first and second adhesives are optionally capable of being functionally cured to provide a structural adhesive bond with a substrate. These adhesives can provide high fracture toughness and high modulus characteristics not otherwise possible in a homogeneous adhesive composition. These adhesives can provide some degree of crack arrestment and significantly reduce the need for mechanical fasteners in industrial bonding applications.
(FR)
L'invention concerne des articles adhésifs et des procédés de fabrication et d'utilisation associés. L'article adhésif comprend une ou plusieurs couches adhésives à motifs comprenant des adhésifs distincts sur les plans compositionnel et spatial qui sont disposés latéralement l'un par rapport à l'autre. Les premier et second adhésifs sont facultativement capables d'être durcis fonctionnellement pour fournir une liaison adhésive structurale avec un substrat. Ces adhésifs peuvent fournir une ténacité élevée et des caractéristiques de module élevé non autrement possibles dans une composition adhésive homogène. Ces adhésifs peuvent fournir un certain degré d'arrêt de propagation des fissures et réduire de manière significative le besoin d'éléments de fixation mécaniques dans des applications de liaison industrielle.
