Microencapsulation of Chemical Additives

A novel process for microencapsulating complex chemical additives suitable for operating at high temperature and pressure.


There is a need for a new process for encapsulating complex chemical additives, where microcapsules can give strong performance under hostile chemical and mechanical conditions. While microencapsulation technique is a mature technology, microcapsule products made by traditional techniques may work well only in relatively simple, passive and non-hostile conditions. On the other hand, in engine lubrication applications, both additives to be encapsulated and the surrounding solution may exhibit complex chemistry. Furthermore, lubrication often operates at high temperature, high pressure, and high shearing environments where microcapsules made by traditional techniques simply do not work well.
