Pharmaceutical & Industrial Coating Materials

Pharmaceutical coating has been an important technique for the manufacture of pills and other medicines, and pharmaceutical coating techniques continue to change and develop as the pharmaceutical industry develops. Modern pharmaceutical coatings are often film-coated tablets, which are made from cellulose derivatives such as hydroxyproply, methylcellulose or other cellulose polymers, such as cellulose ethers, acrylic polymers, and occasionally materials such as polyethylene glycols or polyvinyl alcohol and other waxy materials. A film-coating is a thin, polymer-based coat applied to a pill, and upon close examination the film structure often is non-homogenous - resulting from the deliberate addition of insoluble pigments for coloring, and from the repetitive coating process. A single tablet (pill) is passed through a spray zone, where the adherent material is sprayed and allowed to dry before the next portion of coating; this process is repeated multiple times.

The major studies in the nanotechnology include Nano sized particles, their function and behavior with respect to other systems. Nanotechnology is the ability to understand and control materials at the very smallest scales, from around 100 nm to the dimensions of single atoms; At this Nano scale the properties of these nanosized particles are vary from the conventional medicines.
