‘‘Curing acrylic adhesives’’ can be defined as reactive, cross-linked, high strength structural adhesives that cure by way of free radical initiation. They typically contain methacrylate monomers that are generally toughened with elastomeric polymers as part of the formulation.
Curing acrylic adhesives are distinctly different from anaerobics, cyanoacrylates, and acrylic solution adhesives and emulsions. These related chemistries use different formulating materials, cure via different curing mechanisms, and often possess minimal high performance properties over long periods of time, or when exposed to aggressive environments.
Curing acrylic adhesives were first developed in Germany in the late 1960s as an outgrowth of poly(methyl methacrylate) chemistry. Early formulations were simply low molecular weight solutions of poly(methyl methacrylate) dissolved in methyl methacrylate monomer. These simple systems could be cured by way of peroxide initiation and found utility in bonding aluminum windows and doors. Since that time, a considerable amount of research has occurred resulting in the emergence of the very sophisticated adhesive systems that are on the market today. A considerable amount of the most recent work in developing what are now being referred to as ‘‘high performance acrylic adhesives’’ has been conducted in the United States.
This chapter will cover acrylic chemistry, the various types of acrylic adhesives that have come into existence over the years, advantages and limitations of these systems, properties of adhesives, lap shear strength, what makes these systems unique among other types of adhesives, and examples of performance.
