| Title | Polyurethane (PU) microspheres/ microcapsules |
| Knowhow is available for | Spherical PU microspheres of uniform shape and size used in getting a film of uniform thickness without any defects or fat edges with applications in coatings, paints, powder coating/molding. PU microcapsules that can encapsulate any chemical of interest, that could be later released when required. |
| Summary | A novel process for preparation of polyurethane microspheres of uniform shape, a narrow particle size distribution, size ranging from 1 to 100 micron and molecular weight ranging from 200-2000. The yield is as high as ~60-85%.
A process for the preparation of polyurethane microcapsules that can encapsulate any chemical of interest, that could be later released when required. For ex.: biocides, pesticides, anti-microbial agents, disinfectants, etc.

| Advantages | Microspheres
-Produces a film or coating of uniform thickness without defects or fat edges
-Narrow particle size distribution
-Superior appearance (smoothness, uniform coating thickness)
Microcapsules
-Reduce the environmental/mammalian toxicity otherwise caused
-Controlled Release by microcapsules extends the activity of the agent - increases effective delivery, and longer life
