How well does Brady B-320 adhere to stainless steel, powder coat, and plastic surfaces?

Brady B-320 uses a Specialty adhesive adhesive. For optimum bond strength, surfaces should be cleaned with an isopropyl alcohol (IPA) wipe and allowed to dwell for 24 hours prior to full chemical or mechanical stress.

Which thermal transfer ribbons and Brady printers are compatible with B-320?

The official manufacturer-recommended thermal transfer ribbon for Brady B-320 is Brady Series R4300, R6000 Halogen-Free, or R6200 resin ribbons. Using the recommended resin or hybrid ribbon ensures crisp edge definition, high-density 2D DataMatrix scanning, and compliance with abrasion rub standards. Compatible Brady printers include benchtop industrial systems (i3300, i5100, i7100, BBP33) as well as rugged portable field printers (M510, M610, and M710) depending on the SKU form factor.

How does Brady B-320 withstand industrial chemicals, solvents, and fuels?

Brady B-320 resists common industrial reagents including lubricating oils, water, mild acids, and aliphatic solvents.

Is Brady B-320 UL Recognized, CSA Accepted, or Halogen-Free?

Brady B-320 meets RoHS 2011/65/EU and REACH (SVHC) directives.

What surface preparation is required before installing Brady B-320?

To achieve maximum bond strength, ensure the bonding substrate is clean, dry, and free of machining oils, silicone mold release agents, or dust. Wipe the surface with a 50/50 Isopropyl Alcohol (IPA) and water solution using a lint-free wipe, allow to evaporate completely, and apply firm, uniform roller or thumb pressure across the entire label face.
