One of the oldest pharmaceutical techniques currently in use is tablet coating. Coating is a procedure that involves applying an essentially dry outer layer of coating material to the surface of a dosage form in order to bestow unique benefits over the uncoated kind. It entails coating the tablet with a sugar or polymeric coating. Taste and odour masking, physical and chemical protection, protection of the medicine in the stomach, and control of the release profile are all advantages of tablet coating. Particles, powders, granules, crystals, pellets, and tablets are all examples of oral solid dose forms that can be coated. When coating composition is applied to a batch of tablets in a coating pan, a sticky polymeric film forms on the tablet surfaces. Sugar coating, film coating, and enteric coating are examples of tablet coating processes.
The protective characteristics of industrial coatings are designed and precisely formulated. A resin, a hardener, and a reinforcement make up these composite materials. This is a type of coating that is designed to meet the most stringent chemical and corrosion resistance requirements in the industry. It is constructed of polymer materials, which produce the most durable coatings. They're made for fasteners and steel pipes that hold gases, oils, water, wastewater, and petrochemicals, as well as food processing equipment that needs a non-stick coating. Agribusiness, automobile, and construction equipment all use it.
