No evidence of blistering,
whitening of the coating surface or loss
of adhesion after 240 hours emersion
at 104 degrees F., and 5 minutes recovery.
|
|
Acid Resistance:

No evidence of blistering,
whitening of the coating surface or loss
of adhesion after 24 hours emersion in a
1% hydrochloric Acid solution at 77
degrees F., and 5 minutes recovery.
