  • Two-part structural adhesive having long working time
    Patent number: 6512043
    Abstract: A two-part adhesive comprising acrylic and/or methacrylic monomers, and advantageously toughening agents, impact modifiers including graft co-polymer (core-shell and non core-shell) impact modifiers, carboxylic acids, reducing agents, inhibitors, retarding agents, initiators and chain transfer agents is provided. Particularly advantageous reducing agents include anilines, toluidines, substituted anilines and substituted toluidines. The adhesive composition in accordance with the invention can achieve working times of 40 to 80 minutes or longer at 95° F., exhibits superior low-sliding performance, is resistant to boiling even for larger beads, and is non-sagging. In addition the adhesive composition of this invention achieves superior characteristics of high bonding strength, high impact strength, high tensile strength and high elongation of the cured adhesive.
