Why do I need a license to use Fluoroguard®?
There are several patents (issued and pending) that cover the addition of Fluoroguard® to polymers. That is why we insist on license agreements. Patents exist to cover both thermoplastic and thermoset polymers. There are some applications that are not allowed, such as medical implants over 30 days. Other medical applications must be reviewed case-by-case by DuPont and become part of the license.
