For example, a certain amount of surface conductivity is essential to allow painting side by side with metals in a single streamlined process. 

Many tests are based on constant condensation or humidity. Incidentally, constant condensation is not the same as humidity testing. Condensation rates are higher in the former than the latter because, in constant condensation chambers, the back sides of the panels are at room tempaature and the painted side faces water vapor at 40 C. This slight temperature differential leads to higher water condensation on the panel. If no such temperature differential exists, the conditions provide humidity testing in what is known as a tropical chamber. The Cleveland chamber is one example of condensation testing a salt spray chamber with the salt fog turned off, the heater turned on, and water in the bottom (to generate vapor) is a humidity test... 

The flat cell is illustrated in Fig. 8.5. In this construction, a duplex electrode is formed by coating a zinc plate with either a carbon-filled conductive paint or laminating it to a carbon-filled conductive plastic film. Either coating provides electrical contact to the zinc anode, isolates the zinc from the cathode of the next cell, and performs the function of cathode collector. The collector function is the same as that performed by the carbon rod in cylindrical cells. When the conductive paint method is used, an adhesive must be placed onto the painted side of the zinc prior to assembly to effectively seal the painted surface directly to the vinyl band to encapsulate the cell. No expansion chamber or carbon rod is used as in the cylindrical cell. The use of conductive polyisobutylene film laminated to the zinc instead of the conductive paint and adhesive usually results in improved sealing to the vinyl however, the film typically occupies more volume than the paint and adhesive design. These methods of construction readily lend themselves to the assembly of multi-cell batteries. 

Heat insulating material (thickness 30-50 mm) is usually installed between painted side plates and roof sheets because the temperature of the outside plates can rise up to 80°C and drop below —30°C. Typical materials for heat insulating are oxidized acrylic libers or carbon fibers. They are bonded on the back of outside plates with heat-resistant nitrile rubber adhesives. In some cases, 20-mm-thick heat insulating material is bonded on the back of decorated inside walls. 

In many instances the friction material mix is integrally molded into holes within the backing plate or shoe. Painting of the final assembly, less common in North America, is the rule in Europe and Asia. For controlling brake squeal, noise insulators are widely used. These noise insulating layers are bonded or mechanically attached to the back side of the friction material backing plate. 

Paint Driers and Polymer Additives. Paints based on alkyd resins (qv) dry by the oxidation and cross-linking of unsaturated side chains. Metal catalysts are included in paint formulations to promote this drying. Cerium carboxylates, eg, the naphthenate, are used as through driers, ie, to promote drying in the body of the paint film rather than at the film s surface (44). 

The color development of photochromic compounds can also be utili2ed as a diagnostic tool. The temperature dependence of the fa ding of 6-nitroindolinospiropyran served as the basis for a nondestmctive inspection technique for honeycomb aerospace stmctures (43). One surface of the stmcture to be exarnined was covered with a paint containing the photochromic compound and activated to a violet color with ultraviolet light. The other side of the stmcture was then heated. The transfer of heat through the honeycomb stmcture caused bleaching of the temperature-dependent photochromic compound. Defects in the honeycomb where heat transfer was inhibited could be detected as darker areas. 

Electrostatic spraying is used in shops to coat conductive objects. It is very useful for odd-shaped objects such as wire fence, cables, and piping. An electrostatic potential of 60,000 volts on the object attracts oppositely-charged paint particles the spray can wrap around and coat the side of the object opposite to the spray gun. This technique produces very uniform finishes and has the least paint loss of the three methods. However, it is slow, requires expensive equipment, produces only thin coats, and is sensitive to wind currents. 

Disclosing waxes or pressure indicating pastes, are used in fitting a dental appHance to estabhsh the location and extent of high spots or pressure areas, as on impressions and complete dentures. They are very soft, salve-like compositions that are painted onto the tissue side of an impression or denture. When the wax-coated denture is seated in the mouth, the soft paste is forced out of the areas showing hard contact between the denture and the mucous membrane. These areas on the denture can be easily marked and material removed from the denture to reheve the premature or hard contact. 

Tube-side headers for water sei vice are made in a wide variety of materials carbon steel, copper alloy, cast iron, and lead-hned or plastic-lined or specially painted carbon steel. 

For protective coatings, such as with epoxy paints, the minimum thickness of paint (primer plus paint) should be around 70-80 microns, which is also possible thiough one coat each of primer and paint. If different paint shades are required on outer and inner surfaces paint any one side first, cure it almost completely and then apply the second shade on the other side. Even when there is a wrapping on the second side, can be easily wiped and cleaned, without affecting the first. 

As a consequence of these advantages, these blends are finding particular application for car parts that can be painted on-line side by side with metals at high temperatures. 

An example of the contribution of polar interactions between an acrylic PSA and a substrate is shown in Fig. 6. By copolymerizing iso-octylacrylate and acrylic acid, using a monomer ratio of, respectively, 95/5 and 90/10, two otherwise identical PSAs were made. The PSAs were laminated to both sides of a foam core to make an attachment tape as used in the automotive industry for the application of body side moldings to a car. One side of the foam tape was laminated against an aluminum foil backing. The other side was laminated against an automotive paint-coated panel to make the final test sample. The test sample was allowed to... 

BEOs are most often used for point sources or small line or surface sources. See Chapter 7 for descriptions of sources. BEOs are sometimes used for lines or surfaces when the source is moving along the line or on the surface. This naturally demands the exhaust to move with (or be moved with) the source movements (e.g., during painting or seam welding). They have also been used for side suction from baths and tanks-- and these exhausts are usually called rim exhausts see Rim Exhausts. However, for these sources push-pull systems (Section 10.4.3) are often more efficient. Side hoods can also be used, e.g., when molten metal is poured however, in these cases an enclosed exhaust is more efficient. 

The loss of the Titanic in 1912 has been the subject of many books. The loss of another luxury ship, the Ville du Havre, off the Newfoundland coast in 1873, as the result of a collision, is less well known. The lifeboats were difficult to detach, as the ship was newly painted and everything was stuck fast many could not be detached in time. The life preservers, along the sides of the deck, w ere also stuck fast. Fifty-seven people were rescued, but 226 drowned. On chemical plants, painters have been known to paint everything in sight [12j.
