Encapsulation

Encapsulation is the process of one material enclosing another. Several industries use encapsulation for a variety of different applications. One can encapsulate metal to optimize chemical reactions, and encapsulate metal surfaces to increase long-term corrosion protection. Encapsulation is also important for sealing off lead paint and protecting oil-soluble ingredients from oxidization. Encapsulation provides solutions to a wide range of problems. Microencapsulation also refers to the process of protecting oil-soluble ingredients against oxidization. Manufacturers use molecular encapsulation to mask tastes and odors, stabilize actives like light and temperature, increase the solubility of actives, and reduce volatility. Lead paint is highly toxic and is currently banned in households and other buildings in America. In homes built with lead paint (prior to the year 1978), encapsulation can solve the issue without replacing the paint. In this application, one can only use encapsulants approved by the State’s Register of Approved Products over lead paint. Encapsulation of lead paint is only effective as a barrier on surfaces in good condition, not those that are deteriorated or in high-traffic areas. Encapsulation of electronic parts and devices can lend protection from corrosion and abrasion. In the electronics industry, encapsulation can protect items such as circuit boards from moisture, dust, and harsh chemicals.
