The cover picture shows a GreenCaps microcapsule breaking and releasing encapsulated glycerol after the organosilica microspheres are sprayed from a pressurized polyurethane foam can. This shows how glycerol acts as a solid curing agent, promoting crosslinking of partially polymerized diphenylmethane diisocyanate.
