Brady B-361B: Clear Polyester Film Tape

Brady B-361B is a clear polyester film tape used in a self-laminating format for wire and cable identification: it has a white printable or write-on zone plus a translucent overlaminating area that wraps over the printed text. The lowest application temperature the sheet gives is 50°F (4°C), measured applying to stainless steel, and the one-year shelf life holds only if the product stays in its original packaging below 80° F (27° C) and 60% RH. It prints by laser and thermal transfer, and the sheet credits it with good print smudge resistance, solvent resistance, and elevated temperature performance — though after 30 days at 230°F (110°C) it shows slight discoloration, and the sheet describes the material as discolored but functional up to 130°C.

Extracted directly from Brady Technical Data Sheets to prevent real-world application failures and chemical degradation:

• Regulatory status (RoHS): The sheet states directly, "Brady B-361B is RoHS compliant to 2005/618/EC MCV amendment to RoHS Directive 2002/95/EC." This is the only compliance statement anywhere on the sheet — no agency approvals, listings, or other standards conformance (UL, CSA, MIL, REACH, etc.) are claimed, and no URL is given for further compliance information.
• Lowest application temperature is tied to one substrate: The Application Temperature row gives 50°F (4°C), and the test-method cell for that row reads "Lowest application temperature to stainless steel." The sheet gives no application-temperature floor for textured ABS, polypropylene, or any other surface.
• Elevated temperature causes discoloration: The High Service Temperature result cell reads "Slight discoloration at 110°C; no visible effect to laser print. Material discolored but functional up to 130°C." Discoloration is expected at elevated temperature even where the sheet still calls the material functional.
• One configuration fails where others do not (Methyl Ethyl Ketone): MEK is the only reagent on the sheet producing a "Severe" result, and it does so in exactly one column — the marker applied to 0.080" OD wire ("Severe unwrap"). The same reagent gave only "Slight unwrap" on 0.250" OD wire and "Slight adhesive ooze" on the flat aluminum panel. The severe result must not be generalized to the other two configurations, nor the milder results to the 0.080" wire.
• Unlabeled sentence below the chemical resistance table: "Laser printing legible in all test fluids." It sits directly beneath the chemical table with no row label and no column assignment, so the sheet does not state which reagents or which of the three sample configurations it covers. Quoted here verbatim rather than attributed to any row or column.
• Shelf life is conditional on storage: "Shelf life is one year from the date of receipt for this product as long as this product is stored in its original packaging in an environment below 80° F (27° C) and 60% RH."
• Fitness for use is the customer's to establish: "It remains the responsibility of the user to assess the risk of using this product. We encourage customers to develop testing protocols that will qualify a product's fitness for use in their actual applications."
• Data is not for specification purposes: "Note: All values shown are averages and should not be used for specification purposes." The sheet adds that its test data "shall not be relied upon by Brady customers for designs and specifications, or be relied on as meeting specified performance criteria," and directs customers developing specifications or performance criteria to contact Brady.
• Compliance data provenance disclaimed: Brady states product compliance information comes from raw-material suppliers or from third-party independent laboratory testing, and that "Brady makes no independent representations or warranties, express or implied, and assumes no liability in connection with the use of this information."
• No footnotes on this sheet: Checked — the document contains no superscript footnote markers and no notes appended below any table other than the unlabeled line recorded above.
