BRADY B-429 THERMAL TRANSFER PRINTABLE SATIN WHITE TAMPER EVIDENT LABEL STOCK

TDS No. B-429
Effective Date: 16-Nov-2007

Description:

 

GENERAL

B-429 is a polyolefin film with a permanent rubber pressure sensitive adhesive and a topcoat specifically designed for thermal transfer printing.

 

APPLICATIONS
B-429 is designed for applications like E-PROM labeling and rating plates that require both high performance and protection against removal.

 

SPECIAL FEATURES
B-429 is designed to destroy upon removal. A 24 hour dwell time is recommended for ultimate destructibility.

 

RECOMMENDED RIBBONS
Recommended ribbons are the Brady Ribbons R-7960, R-7961 and R-7962 for optimal print performance.

 

AGENCY APPROVALS
B-429 is a UL-recognized component and CSA accepted material when printed with Brady series R-7960 and R-7961 ribbons. See UL file MH17388 and CSA Acceptance Record LS 28736 for specific details.

CHEMICAL RESISTANCE

Samples printed with Ribbons R-7960, R-7961 and R-7962 using a BradyPrinterTM Model 300 X thermal transfer printer. Samples laminated to aluminium panels and allowed to dwell 24 hours prior to testing. Test conducted at room temperature. Testing consisted of 5 cycles of 10 minute immersions in the specified test fluid followed by a 30 minute recovery period. After final immersion, samples rubbed 10 times with cotton swab saturated with test fluid.
