Plastics are used in virtually all sectors of industry, from the manufacture of mobile phones to automotive engineering. Most plastics are now coated for protection against weathering, attack by solvents and scratching, as well as for decorative reasons. Surface coating of plastic is defined as the process of applying coatings to plastic surface parts to improve the appearance of the surface, to protect the surface from physical or chemical stress, and or to attenuate electromagnetic interference or radio frequency interference that would otherwise pass through plastic housings. Plastic are synthetic polymers formed into panels, housings, bases, covers, or other business machine components. The business machines category includes items such as typewriters, electronic computing devices, calculating and accounting machines, telephone and telegraph equipment, photocopiers, and miscellaneous office machines. Surfaces in general are contaminated by dust, smoke, exhaust gas, organics, bacteria, mold, ultraviolet degradation etc. Various solutions have been proposed to address such surfaces contamination problems. Surface coating techniques using nanoproducts are rapidly advancing globally. Nanotechnology can deliver micro coatings onto surfaces exhibiting different properties. Nanotechnology is attracting a lot of attention from governments, academia and industry. A nanometer is a million times smaller than a millimeter and 10,000 times smaller than anything the human eye can see. Nanoparticles offer huge amounts of surface area. As the object size gets smaller, the surface area to volume ratio becomes larger. Nanoparticles surfaces act as excellent catalyst sites and less amount of material is needed for producing the same effect thus leading to high efficiency, less toxicity, less weight, and/or less costs. The particle size of nano titanium dioxide manufactured worldwide varies from 20 to 50 nanometers. The individual particles are not visible to naked eye, while agglomerates of particles are visible. At the same time, pigmentory titanium dioxide has particle size in the range of 250 and 350 nanometers. The pigmentory titanium dioxide absorbs ultra-violet light and reflects visible light, while the nano particles not only reflects visible light, but effectively transmit visible wave length through the crystals. The nano titanium dioxide was especially useful for automotive coatings when used with pigments like aluminium flakes, which is the most widely used pigment in automobile industry for imparting a metallic look to coatings and also as antimicrobial coatings on plastic surfaces. Nanotechnology and nonmaterial for the industry are at a beginning stage in India but in developed countries this is not a new concept. There is an immense scope and potential in this field. New entrepreneurs should explore and venture into this field.
