I'm looking for a polyurethane with microbial resistance. Doing some research I found two commercial types: DESMOPAN 9392A and DESMOPAN 2792A. Both are manufactured under GMP conditions and limited suitability for use with food contact, but only one of them has microbial resistance. So, I need to know what is the chemical process that gives it the anti-microbial quality.

  • $\begingroup$ Usually what is done is to disperse a toxic substance in the PU. Numerous chemical processes can be used, depending on the type of application. You can search for "polyurethane antimicrobial covestro" in Google Patents to get a feel for what those commercial PUs may use. $\endgroup$ Oct 18 '18 at 23:15
