    BRADY B-542 HIGH TEMPERATURE CREPE PAPER

    TDS No. B-542
    Effective Date: 29-Jun-2011

    Description:
    Brady B-542 masking tape is a tan colored saturated crepe paper with a removable rubber based pressure sensitive adhesive.

    Brady B-542 is used primarily as a solder dip mask or in other making applications where high temperatures are present.

    Brady B-542 has good conformability, has very good resistance to heat, and removes cleanly without adhesive residue from most surfaces.
