Acrylic adhesives, like many other adhesive types on the market today, have had a series of technical improvements often referred to as “generations” or ‘‘families.’’ These so-called ‘‘generations’’ of acrylic adhesives originally did represent fundamental changes in the formulations and significant improvement options to potential users. In recent years, these distinctions have been blurred considerably. Most products on the market today are advanced formulations offering performance, handling, and safety features well beyond products introduced decades earlier. Nevertheless, some of the early nomenclature is still used, and certainly is common in older literature. Consequently, they are reviewed here for historical purposes. In the following sections, each of the important acrylic types is covered separately in an attempt to clarify what they are and how they differ from one another.
