The second edition of this popular industrial guide describes over 2,800 currently available epoxy resins, curing agents, compounds, and modifiers, based on information supplied by 71 manufacturers or distributors of these products. Epoxy resins have experienced tremendous growth since their introduction in the 1950s. Future growth will be in new markets in the specialty performance areas and high-technology applications. Each raw material or product is described, as available, with typical assay or checkpoint figures and a brief summary of important features or applications. Additional sections useful to the reader are the Suppliers' Addresses and a Trade Name Index.

Epoxy resins have been commercially available for about 45 years and now have many major industrial applications, especially where technical advantages warrant their somewhat higher costs. The chemistry of these resins is fascinating and has attracted study by many very able scientists. The technological applications of the epoxy resins are very demanding and there are many new developments each year. The aims of the present book are to present in a compact form both theoretical and practical information that will assist in the study, research and innovations in the field of epoxy resin science and technology. The literature on epoxy resins is so vast that it is not possible to be encyclopaedic and that is not the function of the present text. It is the editor's hope that the selection of topics discussed will provide an up-to-date survey. There is some overlap in the chapters but this is minimal and so each chapter is essentially self contained. As with all chemicals there are toxicological and other hazards. These are not dealt with in this text since a little knowledge can be dangerous, but material supplied can provide information regarding any safety precautions that may be necessary. However, often these precautions are not onerous and epoxy resins, or more specifically the hardeners, can be handled readily. It is hoped that this text will provide an up-to-date outline of the science and technology of epoxy resins and stimulate further research into unsolved problems and assist further technological developments.

A new technique for mixing solid curing agents into liquid epoxy resins using ultrasonic energy has been developed. This procedure allows standard curing agents such as 4,4'-diaminodiphenyl sulfone (4,4'-DDS) and its 3,3'-isomer, (3,3'-DDS) to be mixed without prior melting of the curing agent. It also allows curing agents with very high melt temperatures such as 4,4'-diaminobenzophenone (4,4'-DABP) (242 C) to be mixed without premature curing. Four aromatic diamines were ultrasonically blended into MY-720 epoxy resin. These were 4,4'-DDS; 3,3'-DDS; 4,4'-DABP and 3,3'-DABP. Unfilled moldings were cast and cured for each system and their physical and mechanical properties compared.

Nacre, mother-of-pearl, is an exception from the rule that strength and toughness are generally mutually exclusive in materials. It possesses a unique set of mechanical properties which has been attributed to nacre’s special brick-and-mortar-like microstructure. Consequently, mimicry of this microstructure for similar reinforcement in synthetic materials has been the goal of many researchers so far with excellent results in the area of thin films – but hardly any serviceable outcome in bulk dimensions. This thesis provides a way to fill this gap in processing of bulk-sized nacre-inspired composites. The approach is founded on sedimentation processes that can be rated as more facile, economically more efficient, and geometrically less limited than other methods. Eventually, it results in composites that mimic up to four structural design features of nacre, acting as examples for novel materials that could be applicable in fields ranging from ballistic protection to filtering technologies.

Epoxy is a term used to denote both the basic components and the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resin are a class of thermoset materials used extensively in structural and specialty composite applications because they offer a unique combination of properties that are unattainable with other thermoset resins. Epoxies are monomers or prepolymers that further reacts with curing agents to yield high performance thermosetting plastics. They have gained wide acceptance in protecting coatings, electrical and structural applications because of their exceptional combination of properties such as toughness, adhesion, chemical resistance and superior electrical properties. Epoxy resins are characterized by the presence of a three membered cycle ether group commonly referred to as an epoxy group 1,2-epoxide, or oxirane. The most widely used epoxy resins are diglycidyl ethers of bisphenol-A derived from bisphenol-A and epichlorohydrin. The market of epoxy resins are growing day by day. Today the total business of this product is more than 100 crores. Epoxy resins are used for about 75% of wind blades currently produced worldwide, while polyester resins account for the remaining 25%. A standard 1.5-MW (megawatt) wind turbine has approximately 10 tonnes of epoxy in its blades. Traditionally, the markets for epoxy resins have been driven by demand generated primarily in areas of adhesives, building and civil construction, electrical insulation, printed circuit boards, and protective coatings for consumer durables, amongst others. The major contents of the book are synthesis and characteristics of epoxy resin, manufacture of epoxy resins, epoxide curing reactions, the dynamic mechanical properties of epoxy resins, physical and chemical properties of epoxy resins, epoxy resin adhesives, epoxy resin coatings, epoxy coating give into water, electrical and electronic applications, analysis of epoxides and epoxy resins and the toxicology of epoxy resins. It will be a standard reference book for professionals and entrepreneurs. Those who are interested in this field can find the complete information from manufacture to final uses of epoxy resin. This presentation will be very helpful to new entrepreneurs, technocrats, research scholars, libraries and existing units.
