Effective Date: 09/26/2006

Description:


GENERAL
Print Technology: Thermal Transfer
Material Type: Metallized Polyester
Finish: Matte Silver
Adhesive: Tamper Indicating Acrylic

Brady B-438 is RoHS compliant to 2005/618/EC MCV amendment to RoHS Directive 2002/95/EC.

SPECIAL FEATURES
B-438 is designed to leave a "CHECKERBOARD" footprint when the label is removed. In addition, a "CHECKERBOARD" pattern will appear on the top surface of the label in order to prevent it from being reused. Recommended 24 hour room temperature dwell before removal for full tamper evident performance. The adhesive nature of this product does not allow for repositioning and requires minimal handling in order to prevent prematurely exposed CHECKERBOARD pattern.

Performance properties tested on B-438 printed with alphanumerics, and a 5 mil and 10 mil minimum X dimension barcode using a Series R4300 ribbon and a BradyPrinter™ THT Model 203 Thermal Transfer Printer. Printed samples of B-438 were laminated to aluminum before exposure to the indicated environmental condition.

The tamper evident checkerboard pattern of B-438 was retained after exposure to all of the listed conditions. Laboratory testing has shown that the tamper-evidency checkerboard pattern of this product becomes nonfunctional after exposure to temperatures higher than 104°F.

PERFORMANCE PROPERTY
CHEMICAL RESISTANCE

Samples printed with a BradyPrinter™ THT Model 203 using Brady Series R4300 ribbons and then laminated to aluminum panels. Test was conducted at room temperature after 24 hour dwell. Testing consisted of 5 cycles of 10 minute immersions in the specified chemical reagent followed by 30 minute recovery periods. After final immersion, samples rubbed 10 times with cotton swab saturated with test fluid.
