Gloves Compatible With Blanket Washes And Inks

I visted a small printer who wants to wear light weight gloves. His
blanket wash (Varn Wash V-120: pertrolium naphtha-- including aromatic
petrolium products-- (<50%) stoddard solvent (<45%), and dipropylene
glycol methyl ether (<10%)) rapidly degrades some vinyl gloves he
bought. His medium-weight supported neoprene gloves work OK but don't
allow detail work.

From my own lab experience with similar chemicals and having checked the
Ansell-Edmont, Cole Parmer, and 4H compatability charts, I plan to make
the following suggestion for him to test himself.

Any cautionary words or additional suggestions?

Nitrile Light-Weight Disposable Gloves. These gloves may be degraded
by aromatic pertolium products like xylene and toluene (for example in
paint thinner), but much slower than vinyl gloves. They are suitable
for work with naphthas, stoddard solvent, isopropanol, the petrolium
distillates typically used in oil based inks, and photographic
chemicals-- in other words, most of the chemicals encountered in a print
shop.

Neoprene Medium-Weight Gloves. Operators indicated that this
currently used product appeared to work. This medium weight neoprene is
not recommended for aromatic petrolium products. It may also be degraded
by napthas and stoddard solvent. It is good for photographic chemicals.
Therefore, these gloves should be replaced regularly when used with your
blanket wash.

Polyvinyl Alcohol Medium-Weight Gloves. I do NOT recommend that you
buy these gloves because they may fail when exposed to isoproyl alcohol
or the acids and bases in photographic chemicals. However, this is a
material that will provide excellent protection to aromatic pertrolium
products. They are typically ten times more costly than neoprene
gloves.

Of course, changing to a lower VOC blanket wash-- a seperate
recommendation-- may make glove selection easier.
