TDS No. B-490

Effective Date: 26-Sep-2006

Description:

GENERAL
Print Technology: Thermal transfer
Material Type: White polyester
Finish: White film with matte white thermal transfer printable coated ink
Adhesive: Permanent acrylic

APPLICATIONS
B-490 Freezerbondz™ markers are designed for use in laboratory identification such as vials, centrifuge tubes, test tubes, straws, and slides.

RECOMMENDED RIBBONS
Brady Series R4300
R6200 (alternate)*
*B-490 can be printed with R6200 ribbon; please note that testing described in this Technical Data Sheet was performed on materials printed with the R4300 ribbon.

REGULATORY APPROVALS

Brady B-490 is RoHS compliant to 2002/618/EC MCV amendment to RoHS Directive 2002895/EC.

SPECIAL FEATURES
B-490 Freezerbondz™ markers can be applied to frozen surfaces including glass and polypropylene stored in liquid nitrogen. B-490 has good print smudge resistance, solvent resistance, and good high and low temperature performance. B-490 performs well in common laboratory environments such as liquid nitrogen and autoclave applications. For tube/vial applications B-490 must be wrapped upon itself with at least 1/8 inch overlap.

ENVIRONMENTAL PERFORMANCE PROPERTIES - LABEL APPLIED TO ROOM TEMPERATURE SURFACE

B-490 samples were printed with Series R4300 ribbon on Bradyprinter™ THT Model 300X-Plus thermal transfer printer. Printed B-490 samples were laminated at room temperature to surfaces listed below and allowed to dwell 24 hours at room temperature prior to exposure to the indicated environments. Labels applied to glass test tubes (1.1 cm outer diameter) and polypropylene centrifuge tubes (1.1 cm inner diameter, 1.5 ml capacity) were wrapped with a 1/8" overlap.

ENVIRONMENT	TEST METHOD	TYPICAL RESULTS
High Service Temperature	30 days at elevated temperatures	Slight discoloration at 266°F (130°C), no visible effect to print. Material discolored but functional up to 320°F (160°C)

ENVIRONMENTAL PERFORMANCE PROPERTIES - LABEL APPLIED TO COLD SURFACE

B-490 samples were printed with Series R4300 ribbon on Bradyprinter™ THT Model 300X-Plus thermal transfer printer. Surfaces listed below were stored for 24 hours in either liquid nitrogen at -320°F (-196°C) or in a freezer at -94°F (-70°C). Printed B-490 samples were then laminated immediately after removal of the surfaces form liquid nitrogen or freezer. Samples were alowed to dwell 24 hours at room temperature prior to exposure to the indicated environments. Labels applied to glass test tubes (1.1 cm outer diameter) and polypropylene centrifuge tubes (1.1 cm inner diameter, 1.5 ml capacity) were wrapped with a 1/8" overlap.

PERFORMANCE PROPERTIES - CHEMICAL

Flat samples of B-490 were printed with Series R4300 ribbon onBradyprinter™ THT Model 300X-Plus thermal transfer printer. Printed samples were laminated and allowed to dwell 24 hours prior to testing. Test conducted at room temperature. Samples were immersed in test solvents for 15 minutes. The samples were removed and rubbed 10 times with a cotton swab saturated with the test fluid. The rating scale below shows the effect to the quality of the print for each sample.

CHEMICAL REAGENT	EFFECT TO PRINT WITH RUB	EFFECT TO PRINT WITHOUT RUB	EFFECT TO LABEL STOCK
Ethanol	2	1	No visible effect
Toluene	3	1	Slight adhesive ooze
Isopropanol	2	1	No visible effect
Xylene	3	1	Slight adhesive ooze
Dimethylsulfoxide (DMSO)	2	1	No visible effect
Methylene Chloride	4	1	Slight adhesive ooze
50% Acetic Acid	1	1	No visible effect
10% Sodium Hydroxide	1	1	No visible effect
10% Clorox® Bleach Solution	1	1	No visible effect

Rating Scale:
1=no visible effect
2=slight smear or print removal, detectable but minimal smear
3=moderate smear or print removal (print still legible)
4=severe smear or print removal (print illegible or just barely legible)
5=complete print and/or topcoat removal
