PERFORMANCE PROPERTY

CHEMICAL RESISTANCE

Samples printed with Series R2000 and R5000 ribbons and laminated to aluminum panels and allowed to dwell 24 hours prior to testing. Test conducted at room temperature. Testing consisted of 15 minute and 24 hour immersions in the specified test fluid followed by rubbing on print 10 times with cotton swab saturated with test fluid.

15 MINUTE IMMERSION

24 HOUR IMMERSION

*Yellow and green labels had moderate to severe fade or discoloration in this solvent, all other labels had no visible effect unless mentioned. Overall the green topcoat had slight to severe discoloration in the following chemicals: Methyl Ethyl Ketone, 1,1,1-Trichloroethane, Methyl Alcohol, Gasoline, Mineral Spirits, SAE 20 Wt Oil, Skydrol® 500B-4 and 10% NaOH.
