Coating flexibility

The use of small electrochromic points allows the construction of monochromic or multichromic flat screens. Using different conducting polymers with complementary colors on ITO-coated flexible plastics (now available commercially), camouflage cloths can be envisaged which, once connected to a video camera and a system of image treatment, would be able to mimic any surrounding, as chameleons or cuttlefish do. 

Uses Plasticizer in PVC flooring and other flexible PVC products (e.g., bottles, garden hoses, fishing lures, fabric coatings, flexible medical plastics, tarps, and awnings), films, and sheets in vacuum pumps. Also used in fluorescent lighting ballasts manufactured after 1979 as a replacement for PCBs (U.S. EPA, 1998).

In addition to its use in PTT, 1,3-propanediol can replace traditional glycols in urethane-based polymer systems, improving thermal and hydrolytic stability. As a partial substitute for traditional glycols in polyester systems, 1,3-propanediol can improve coating flexibility without affecting other key properties. Other applications include engine coolants and water-based inks (33). 

The choice of the light source—form, emitted wavelengths, radiant power— depends inter alia on whether Ti02 is unsupported or supported, and on the type and shape of the supporting material. For example, a Ti02-coated flexible material can be wrapped around a cylindrical lamp placed inside the reactor. A plate covered by Ti02 can be installed perpendicularly to the beam of a lamp located outside the reactor. Obviously, the choice of the lamp, especially of the emission characteristics, also depends on the objective. For instance, in view of solar photocatalytic applications, lamps mimicking solar irradiation at the Earth s level or a solar box can be used in the laboratory.

Coatings, especially PVC, contain plasticisers to render the film coating flexible over a range of utility temperatures. There are a wide variety of plasticisers available in the form of aliphatic and aromatic phthalates, sebacates, ricinoleates, adipates, phosphates, oleates, stearates, pahnitates, lactates andglycollates. Dioctyl phthalate is typically known for its use in PVC coatings. 

Attempts have been made over time to improve the physical properties of novolacs. The use of phenol formaldehyde resins prepared in alkaline medium in photoresist compositions is mentioned in a Kalle Co. AG patent. The use of polyvinyl ethers in combination with novolacs to impart stickiness and plasticization action to the latter was patented by Christensen. Steinhoff, Isaacson, and Roelants of the Shipley Company mention the use of vinyl ethers in a patent on roller coating. Lower alkyl polyvinyl ethers, such as methyl, ethyl, butyl, and isobutyl, are added to novolac resins to improve coating flexibility and adhesion to metal surfaces as well as to improve resistance to mildly alkaline solutions. The use of styrene, methyl styrene, and styrene-maleic anhydride copolymers in combination with novolac was mentioned in several patents of both Shipley and Kalle Co. AG. When novolac is copolymerized with maleic anhydride, a resin that is readily soluble in alkaline solutions is obtained. ... 

A complete coating system, recommended for highly demanding situations, consists of several layers - the primer, the intermediate coats and the topcoat. The primer is an essential component for corrosion protection, because it is responsible for the adhesion of the coating to the substrate and also it provides most of the anticorrosive properties, through the use of inhibitors. Its requirements are a good adhesion to the substrate and to the intermediate coat, flexibility and cohesion and good chemical resistance. 

Phenolic Resins. Phenolic resins react with high molecular mass epoxy resins on heating. Such systems are used as gold lacquers to line food containers. The similarly synthesized bisphenol A resols produce colorless coatings with a higher chemical resistance, less odor during cure, and less alteration of the taste of food in contact with the coating. Flexibility is, however, lower than with standard phenolic resins.
