TECHNOLOGY DESCRIPTION

This invention demonstrates solid or semi-solid microparticles that undergo crosslinking and polymerization upon contacting a substrate to form a coating. The microparticles are maintained in an un-reacted state until delivered using cold spray processes where they are propelled using a gas stream at a pre-determined temperature and velocity. The process does not require volatile organic solvents or aqueous vehicles, nor plural component spray or two component formulations with limited shelf life but still deliver uniform coating.

 

 

ABOUT THE LEAD INVENTOR

Prof. Jessica Schiffman is a professor in the Department of Chemical Engineering at the University of Massachusetts Amherst. Her research interests lie in The Schiffman laboratory is an interdisciplinary and imaginative research team that uses “greener” materials science and engineering to address grand challenges in human health.
