We show the first evidence that the microporous GreenCaps organosilica microspheres, functionalized with glycerol and sprayed from a pressurized one component polyurethane foam completely break and release their functional payload, thereby noticeably increasing the rate and the extent of the foam's curing. Further positive results concerning the main froth parameters used by urethane foam manufacturers in the presence of the GreenCaps confirm the potential of these materials to cure better and greener spray polyurethane foams.
