Krytox flourine a problem?

Vince,

Glad you brought this up...

According to the Krytox MSDS (govt. mandated Material Safety Data
Sheet), you don't have to worry about flourine except in cases where
the temperatures exceed 500+ degrees F.

Skin contact can be irritating, but only as a rash. (I've never
experienced this, but it's on the MSDS)

No carcinogens, basically inert stuff.

You don't want to be careless with this stuff, but at the price you
prob'ly won't be!<G> As long as you are careful about washing hands,
cleaning clothes, and keeping things below 500 degrees, you should be
okay. And good ventilation is a good thing in ALL machining
operations!

Hope this helps,

Ballendo

P.S. There has been some concern about teflon coated baking pans,
which ARE used at elevated temperatures... Also about aluminum and
its relation to Alzheimers. Be informed, keep clean, and be careful...
