Resulting Properties

The cure of acrylic adhesives is initiated by a two-part redox reaction system. One component of the redox reaction is present in the base component of the adhesive, and the second component is present in the accelerator or “curing” component. Various tougheners have been used in thermosetting acrylic adhesives. Strong acids such as acrylic, methacrylic, or maleic acid are used to enhance adhesion to metal and plastic surfaces.
