The importance of binder handling strength to shape preservation is emphasized. The chapter provides information on the binders used for room-temperature shaping, namely slurry and tape casting systems.

This chapter discusses the particular corrosion problems encountered and the methods of control used in petroleum production and the storage and transportation of oil and gas up to the refinery. It begins by describing those aspects of corrosion that tend to be unique to corrosion as encountered in applications involving oil and gas exploration and production. This is followed by a section reviewing the methods of corrosion control, namely the proper selection of materials, protective coatings, cathodic protection systems, use of inhibitors, use of nonmetallic materials, and control of the environment. The chapter ends with a discussion on the problems encountered and protective measures that are based on the state-of-the-art as practiced daily by corrosion and petroleum engineers and production personnel.

Generally, binders consist of at least three ingredients: a backbone to provide strength (compounds such as polyethylene, polypropylene, ethylene vinyl acetate, and polystyrene); a filler, such as polyacetal and paraffin wax, to occupy space between particles; and additives, such as stearates, stearic acid, or magnesium stearate, as well as phosphates and sulfonates, to adjust viscosity, lubricate tooling, disperse particles, or induce binder wetting of the powder. In the case of binders deposited via ink jet printing, the binder contains solvents to lower the viscosity for easier jetting. The chapter provides a detailed description of these constituents. The requirements of a binder as well as the factors determining the physical and thermal properties of polymers are discussed. Then, two factors associated with solvation of polymers, namely solubility parameter and wetting, are covered. The chapter ends with information on the specification of polymers used in binders.
