A coating material that is resistant to chemical attack like oxidizing agents is called chemical resistance coatings. Chemical resistant coatings is used as binders for exterior-use paints, traffic paints and foil lacquers. Polyethylene and epoxies are good examples for chemical resistance coatings.
Chemical Resistant Mortar is used for bonding chemical-resistant brick or tile. It has an intimate mixture of liquid resin and a powder in proper proportion is mixed at ordinary temperature to form trowel able mortar that subsequently hardens.
Chemical sensors are more complex extensions of physical sensors. These sensors are defined as measurement devices, which utilize chemical reactions to detect and quantify a specific analyte or event. It utilizes specific polymeric membranes, either per se or containing doping agents, or are coated with non-biological materials. These polymeric layers or specific chemicals have attached to the layers or directly to the transducer, interact with and measure the analyte of interest. The basic components of chemical sensors include active surface, the transducer, and the electronics/software. The active surface of chemical sensors contains the detection component that includes polymeric layer.
