DuPont Krytox® Products are considered mixtures and may also contain substances which have later registration dates. The polymers themselves are not subject to registration and therefore their SDS include neither registration numbers nor exposure sceanrios for these monomers.

These products may also contain substances for which DuPont is considered a Downstream User (DU). More information on the registration status of these substances (registration numbers, uses, etc.) will be communicated in our SDS.
