From Adhesives Technology Handbook

Overview

This chapter discusses individual adhesive types in detail. As a matter of convenience, the adhesives have been arranged in alphabetical order without regard to classification. See Chapter 4 for classification of adhesives.

Certain general categories are also listed, such as alloys, aromatic polymer, conductive, delayed-tack, elastomeric adhesives, anaerobic, film and tape adhesives, hot-melt adhesives, inorganic glues, microencapsulated adhesives, rubber-based adhesives, solvent-based systems, thermoplastic resin adhesives, thermosetting-resin adhesives, and water-based adhesives.

We begin with a brief overview of the modern history of adhesive compounds. Practically all adhesives were derived from plant or animal sources prior to the twentieth century. The main classes included glue from animal bones, fish glue, and vegetable adhesives. Progress in organic chemistry and an increase in demand for adhesives led to the development of synthetic compounds beginning with phenol-formaldehydes and casein adhesives. Developments in polymerization and adhesive chemistry proceeded in a near parallel fashion. An approximate chronological list of adhesive development is given below:

1920s:

Cellulose ester, alkyd resin, cyclized rubber in adhesives, polychloroprene (neoprene), soybean adhesives

1930s:

Urea-formaldehyde, pressure-sensitive tapes, phenolic resin adhesive films, polyvinyl acetate wood glues

1940s:

Nitrile-phenolic, chlorinated rubber, melamine-formaldehyde, vinyl-phenolic, acrylic polyurethanes

1950s:

Epoxies, cyanoacrylates, anaerobics, epoxy alloys

1960s:

Polyimide, polybenzimidazole, polyquinoxaline

1970s:

Second-generation acrylic, acrylic pressure-sensitive, structural polyurethanes

1980s:

Tougheners for thermoset resins, water-borne epoxies, water-borne contact adhesives, formable and foamed hot melts

1990s:

Polyurethane-modified epoxy, curable hot melts, UV and light cure systems

2000s:

Water-borne adhesives, reduced volatile organic compounds, solvent-free one- and two-part adhesives

Products & Services
Industrial Adhesives
Industrial adhesives consist of hot melt adhesives, epoxy adhesives, polyurethane adhesives, sealants, thermoset adhesives, UV curing adhesives, silicon adhesives, acrylic adhesives and other related industrial products.
Pressure Sensitive Adhesives (PSA) and Contact Adhesives
Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.
Adhesive Tapes
Adhesive tapes are used to assemble materials or parts together using a sticky chemical bond.
Rubber Adhesives and Sealants
Rubber adhesives and sealants are highly flexible, natural or synthetic materials that are used to join components or fill gaps between seams or on surfaces.
Anaerobic Adhesives and Anaerobic Sealants
Anaerobic adhesives and anaerobic sealants cure in the absence of air or oxygen.
