Palermo, Italy -- One-component polyurethane foams can be cured more effectively and sustainably with aqueous glycerol as a solid curing agent, according to new university research.
The team based at the Institute for the Study of Nanostructured Materials - which belongs to the National Research Council of Italy - said that tests of organosilica microspheres functionalised with aqueous glycerol as solid curing agents for polyurethane foams "confirm[ed] the potential of these materials to cure better and greener PU foams."
The development has been termed GreenCaps and will now be tested in pre-commercial applications.
