Performance properties were tested on B-7641 white and yellow sleeves printed with the R6000 Series, R4300 Series and Brady 356126 thermal transfer ribbons.  The results are the same for both colors and ribbons unless noted.  Sleeves were tested shrunk on the appropriate sized wires.

Solution A : 1 part isopropyl alcohol, 3 parts mineral spirits

Solution B : deleted from MIL-STD-202, Method 215J

Solution C : BIOACT®EC-7R^TM terpene defluxer

Solution D : 42 parts water, 1 part polypropylene glycol monomethyl ether, 1 part monoethanolamine at 70°C

Sleeves  were printed with  R6000 Series, R4300 Series and Brady 356126 thermal transfer ribbons, allowed to dwell 24 hours prior shrinking on appropriate sized wires and testing.  Testing was conducted at room temperature and consisted of five cycles of 10 minute immersions in the specified chemicals followed by 30 minute recovery periods.  After the final immersion, the samples were removed from the test fluid and the printed image rubbed 10 times with a cotton swab saturated with the test fluid.  The rating scale below shows the effect to the quality of print for each sample.

Unless otherwise noted, there was no visible effect to the printed image prior to rubbing for the above ribbons.

Rating Scale:

1=no visible effect

2=slight fading or print removal

3=moderate fading or print removal (print still legible)

4=severe fading or print removal (print illegible or just barely legible)

5=complete print removal

NP=print removed prior to rub

*tested in JP-8 Jet fuel
