Water bases and

Ferrites are oxides and thus rather inert with respect to water, bases, and organic solvents. However, they may be attacked by acids having sufficiendy high strength (pH < 2), for instance... 

Ink Types. There are 10 gravure ink types categorized by the binders or solvents used A, aUphatic hydrocarbon B, aromatic hydrocarbon C, nitrocellulose D, polyamide resins E, SS nitrocellulose M, polystyrene T, chlorinated mbber V, vinyls W, water-based and X, miscellaneous. 

Emulsion paints These materials are water based and cure by coalescence as the water evaporates. Films formed... 

Electrodeposition This method of paint application is basically a dipping process. The paint is water-based and is either an emulsion or a stabilised dispersion. The solids of the paint are usually very low and the viscosity lower than that used in conventional dipping. The workpiece is made one electrode, usually the cathode, in a d.c. circuit and the anode can be either the tank itself or suitably sized electrodes sited to give optimum coating conditions. The current is applied for a few minutes and after withdrawal and draining the article is rinsed with de-ionised water to remove the thin layer of dipped paint. The deposited film is firmly adherent and contains a minimum of water and can be stoved without any flash-off period. This process is used for metal fabrications, notably car bodies. Complete coverage of inaccessible areas can be achieved and the corrosion resistance of the coating is excellent (Fig. 14.1).

Milk contains both organic and inorganic components. A majority of the milk is water based, and contains water-soluble solutes such as calcium compounds. But milk also contains as much as 15 per cent by mass of water-insoluble, fat-based compounds. 

Most hand creams are colloidal, and generally have a thick, creamy consistency. The majority of hand creams are formulated as a liquid-in-liquid colloid (an emulsion), in which the dispersion medium is water based, and the dispersed phase is an oil such as palm oil or cocoa butter . These oils are needed to replenish in the skin those natural oils lost through excessive heat and work. 

The effect of environmental legislation on the adhesives and sealants market in Europe is outlined. More efficient water-based and hot melt methods it is said are being developed in response to the tightening of environmental legislation. A report by Frost Sullivan is said to indicate further changes and developments in the core adhesives, sealants and related products market. 

Direction of innovation tfrom the standpoint of market actors - 6al Automotive manufacturers substantiate the reduction of solvent emissions by water-based and powdered coatings on the basis of emission statistics. However, the automotive manufacturers state the improvement of the surface quality with the simultaneous improved cost-effectiveness of procedures as the decisive criterion for successful innovation. 

Drilling muds are fluids that are pumped into the bore holes to aid in the drilling process. Most are water based and contain barite, hgnite, chrome lignosulfate, and sodium hydroxide [11], but oil-based drilling muds are still used for economic and safety reasons [12]. Used muds can be removed by vacuum trucks, pumped down the well annulus, or allowed to dewater in pits, which are then covered with soil or disposed of by land farming. 

Since the magnetic fluid appeared, techniques for l he production of variety of magnetic fluids including water-based and oil-based magnetic fluids were developed. Recently a number of magnetic fluids prepared by a variety of methods are on markets (19). 

The process of drilling for crude oil and natural gas generates waste drilling fluids or muds, which are often disposed of by land farming. Most of these fluids are water based and contain barite and other metal salts. Thus barium may be introduced into soils as the result of land farming these slurried reserve pit wastes (Bates 1988). 

There are currently four main types of inkjet inks phase-change, solvent-based, water-based, and UV curable. Other types exist, but are less prevalent, such as oil-based and hquid toner (for electrostatic inkjet technology). Hybrid versions of the four main types also exist (e.g., water-based inks containing some amount of solvent). The various inkjet ink types will be discussed briefly in this chapter, and will be followed by detailed description in separate chapters (solvent-based, water-based, and UV cmable inks). 

Conventional water-based and non-aqueous inkjet inks are mixtures of several components, including volatile solvents, dissolved materials, and dispersed solids (for pigment inks). When the ink reaches the nozzles prior to jetting, the volatile components may evaporate from the nozzle. Therefore, the liquid in the vicinity of the nozzle can have a composition which differs from that of the bulk ink which is further back in the print head supply channels. This disparity causes differences in the physicochemical properties of the ink (e.g., an increase in viscosity or decrease in surface tension)... 

A more sophisticated safety fuse is made by coating the fuse with spray-on plastic from an aerosol can. When this dries the fuse is coated with rubber mold compound, bought at any hobby store. The plastic is used first because the mold compound has a water base and would wet the fuse. The rubber would dry but the fuse would stay damp indefinitely. 

Ethyl acrylate monomer is used to make acrylic resins as well as emulsion (water-based) and solution (solvent-based) polymers. Water-based ethyl acrylate...
