In houseware, fluoropolymers are applied as nonstick coatings for cookware and appliance surfaces. These applications depend on thermal and chemical resistance as well as anti-stick performance. PTFE and ETFE are chosen to insulate appliance wiring that must withstand high temperatures. 

C) prepared by the polymerization of tetrafluoroethene under pressure (45-50 atmospheres). The reaction requites an initiator, ammonium petoxosulphate. The polymer has a low coefficient of friction and its anti-stick properties ate probably due to its helical structure with the fluorine atoms on the surface of an inner ting of carbon atoms. It is used for coating cooking utensils and nonlubricated beatings.

In 1990, a solid-phase immunobead assay (SPIA), with colored polystyrene particles coated with anti-CTX monoclonal antibody (MAb-CTX) began to be used for direct detection of ciguatoxins adsorbed on bamboo paddles coated with organic correction fluid. The membrane immunob-ead assay (MIA) presented by in 1998 Hokama et al. is based on the immunological principles used to develop the SPIA, using a MAb-CTX coated onto colored polystyrene beads. The polyether toxins extracted from a piece of fish tissue bind to the hydrophobic membrane on a plastic support (membrane stick), and can be detected with the MAb-CTX coated onto the colored polystyrene beads. The color intensity of the membrane is related to the concentration of the toxin bound to the membrane. 

Plastic film or laminate applied at the final stages provides high flexibility and suitability for deep drawing, while others are resistant to rain, sun, heat, fire, staining, abrasion and chemicals. Pre-coated metals are available with additional functional features such as anti-bacterlal, antifingerprint, anti-dirt, easy clean, non-stick and heat reflective. 

Anti-adhesive agents have been sought to prevent the sticking of the bacteria to teeth but generally these have not been successful, and bacteriocides are normally used. The problem is the mechanism of the bacterial adhesion, as shown in Fig. 12.25. It is thought that a fdm of polymer from saliva first attaches to the hydroxyapatite. Then bacteria attach to this coating. The bacteria produce a complex layer of cell sheath which glues the cells to each other. 

Immunological detection of ciguatoxins and related polyethers has received particular attention compared to other marine toxins. The initial RIA and enzyme immunoassay employing a polyclonal sheep anti-ciguatoxin antibody revealed cross-reactivities between ciguatoxins and other polyether toxins, suggesting the need for monoclonal antibodies. The availability of monoclonal antibodies allowed for the development of stick enzyme immrmoassay methods and solid-phase immunobead techniques (known as the paddle test), which successfully recognized toxins attached to correction fluid-coated bamboo sticks or paddles previously exposed to toxic fish tissues. 

The uncured rubber, or stock, must fulfil several requirements to allow its successful presentation at the injection press. Most injection units are fed with strip rubber. The strip has to be of regular section and appropriate size. It should not be distorted or kinked and it should show little tendency to stick to itself. These are all features that are controlled by the choice of dump mill take-off machinery and selection of anti-tack agents. The latter should add sufficient coating to the surface of the rubber to leave the strip dry and dustless. Commercially available soap solutions have been found to be almost universally suitable for this purpose.
