Carbon Black Content for Medical-Grade Coatings

coatingengineer · Mar 7, 2008

Hi.

Anyone know permissible carbon black levels for use in medical-grade, non-implantable coatings?

Any empirical data available with respect to cytotoxicity?

Thanks!

Hi.

Anyone else interested? I've found my answer.

While carbon black was reclassified 'Group 2B' some time ago, the route of entry was inhalation (by rats).

To be classified a carcinogen or reproductive toxin, by OEHHA'a own definition, carbon black must meet the following criteria:

1) airborne
2) unbound
3) respirable size

But, within polymeric films (coatings), carbon black is encapsulated. ..."Exposure to carbon black, per se, does not occur when it remains bound within a product matrix, such as rubber, ink, or paint."
