Book excerpt: This collection of critical reports covers the technology of the materials produced by the chemist known as contact, hot melt, and toughened adhesives. Coverage includes the preparation and curing of silicone polymers for adhesives, sealants, and coupling agents (primers). The final chapter discusses the methods and materials used by marine organisms to attach themselves to varied substrates, to their advantage, but often to man's disadvantage. These adhesives are all polymers of one sort of another and they are used by engineers in industries ranging from airplane manufacture to yacht building. The polymers used for contact adhesives are formulated with tackifying resins which must be in molecularly intimate contact with the polymer. The alternative solvent-free hot melt adhesives can be similarly compounded with additives, but variations in the base polymer are more easily achieved with the synthesis of a range of copolyesters or polyamides. Modern structural adhesives are toughened either by precipitation of a second phase from solution in a polymer or by the direct incorporation of finely dispersed rubber. All this and more is revealed in detail for the reader with a background in chemistry.
