CURABLE PRECURSORS OF STRUCTURAL ADHESIVE COMPOSITIONS INCLUDING SELF-POLYMERIZABLE TOUGHENING AGENT, AND METHODS OF USING SAME

Provided are curable precursors of structural adhesive compositions including epoxy resin, a thermally activatable curing agent, and toughening agents. One of the toughening agents includes a free-radically self-polymerizable material. Partially cured precursors are also provided in which the toughe...

description Provided are curable precursors of structural adhesive compositions including epoxy resin, a thermally activatable curing agent, and toughening agents. One of the toughening agents includes a free-radically self-polymerizable material. Partially cured precursors are also provided in which the toughening agent includes a free-radically self-polymerization reaction product of the self-polymerizable material. Additionally, methods of manufacturing a structural adhesive article and bonding together two parts are provided. La présente invention concerne des précurseurs durcissables de compositions adhésives structurales comprenant une résine époxy, un agent de durcissement pouvant être activé thermiquement et des agents de renforcement. L'un des agents de renforcement comprend un matériau auto-polymérisable par voie radicalaire. L'invention concerne en outre des précurseurs partiellement durcis dans lesquels l'agent de renforcement comprend un produit de réaction d'auto-polymérisation radicalaire du matériau auto-polymérisable. L'invention concerne en outre des procédés de fabrication d'un article adhésif structural et de liaison de deux pièces l'une à l'autre.
