  • The chapter commences by reviewing the properties of the broad classes of materials used in film coating, polymers, plasticizers, pigments and solvents (or vehicles). An initial consideration of the polymers shows that while processing is most commonly performed using these materials in solution, there are systems which utilize polymers in suspension in water. The mechanism of coalescence and film formation for these types of materials are discussed.

  • While selecting the coating material, we encounter a barrier caused by the fact that numerous properties expected from an ideal coating are impossible to be obtained simultaneously. For example, an increase in hardness and strength causes the reduction of the coating’s ductility and adherence to the substrate.

  • The known dependency between the hardness and abrasion resistance became the foundation for the development of harder and harder coating materials. The progress in the field of producing coatings in the physical vapour deposition process enables the obtainment of coatings of nanocrystal structure presenting high mechanical and usable properties.

  • The chemical process industries (CPI), petroleum and allied industries apply physical as well as chemical methods to the conversion of raw feedstock materials into salable products. Because of the diversity of products, process conditions and requirements, equipment design is often unique, or case specific. The prime requirement of any piece of equipment is that it performs the function for which it was designed under the intended process operating conditions, and do so in a continuous and reliable manner.

  • Automation of coating processes Graham C.Cole SUMMARY Current Good Manufacturing Practice (cGMP) and the demands of the regulatory authorities worldwide requires greater care in the design of manufacturing facilities, the selection of materials used in their construction, their layout, the equipment used in the preparation of tablets to be coated and the coating operation. It is claimed that robotic systems will eventually take over all processing tasks! (Kanig & Rudic, 1986).

  • Modified release coatings John E.Hogan SUMMARY Relevant aspects of the composition and performance of modified release coatings are considered in this chapter. Initially, the basic characteristics of multiparticulate systems are described and comparisons are made with the performance of whole tablets intended for modified release. The properties and effects of the polymers and plasticizers which are used in modified release coatings are illustrated with examples from the literature. This further develops the basic treatment of these materials provided in Chapter 2.

  • Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer. 1.4 The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

  • Every day countless kilometres of steel pipelines are installed worldwide for the most varied civil and industrial uses. They form real networks comparable to a system of road networks, which, although not so obvious, are definitely much more intricate and carry fluids that have become essential for us. To comply with technical specifications and fulfil the necessary safety requisites, special materials and welding processes which have evolved with the sector have been developed in recent years.

  • A basic understanding of rheology and surface chemistry, two primary sciences of liquid flow and solid–liquid interaction, is necessary for understanding coating and printing processes and materials. A generally qualitative treatment of these subjects will suffice to provide the insight needed to use and apply coatings and inks and to help solve the problems associated with their use.

  • The application of the nanostructure coatings is seen as the solution of this issue (Voevodin et al., 2005; Yang et al., 2007). According to the Hall–Petch equation, the strength properties of the material rise along with the reduction of the grain size. In case of the coatings deposited in the PVD processes, the structures obtained with grain size ~10 nm cause the obtainment of the maximum mechanical properties.

  • This type of coatings is also characterized with a large number of grain boundaries with a crystalline/amorphous transition across grain–matrix interfaces, restricting the rise and development of cracks. Such mechanism explains the resistance to fragile cracking of nanocomposite coatings (Veprek, 1997; Veprek, 1998; Rafaja et al., 2006).

  • High hardness and strength of the nanocomposite coatings are due to the fact that the movement of dislocations is suppressed at small grains and in the spaces between them, which causes the appearance of incoherent deformations. When the grain size is reduced to that of nanometres, the activity of dislocations as the source of the material ductility is restricted.

  • Due to the widespread use of ceramic coatings, several synthesis techniques have been developed in recent decades. The majority of these techniques, such as chemical vapor deposition (CVD) and physical vapor deposition (PVD) and their variants, are focused on the synthesis of flat coatings. Recently, the preceramic polymeric synthesis route has offered the possibility to impregnate preceramic materials into porous matrices prior to pyrolysis in order to create coated or composite materials This technique, however, leads to pore filling and alterations of the original substrate texture....
