Go to Microencapsulation


With more than 70 years of experience in encapsulation technology at the micro- and nanoscales, we can solve your application problems by using a wide variety of microencapsulation and particle coating technologies. Our full range of services includes feasibility studies, product and process optimization, pilot-scale production, equipment fabrication, and scale and system integration. Customized microcapsules and microspheres can be developed for dissolution due to heat, chemical change, and friction, depending on application.

Microencapsulation Coating Technologies

We focus on solving customer application problems using a wide variety of microencapsulation and particle coating technologies. These services are offered to a broad spectrum of industries such as food, pharmaceutical, cosmetic, consumer and personal care products, agricultural veterinary medicine, industrial chemicals, biotechnology, biomedical, and sensors. For more than 70 years, extensive research efforts have developed custom-made microcapsules and microspheres by selecting appropriate shell compositions, depending on product application. Typically, the goal is to establish proof-of-concept for a viable product application. Once successful, SwRI offers pilot plant scale-up capabilities, production experience, and product assistance to deliver encapsulated product for the commercial market.

SwRI microencapsulation is a vertically integrated, world-class microencapsulation capability that offers a broad-based technology platform in microencapsulation techniques. We provide quality service including feasibility study, product and process optimization, production, equipment fabrication/sale and system integration.
