    We slit in rolls or die-cut to your exact specifications.

    Features: 

    • This tape has a moisture resistant polycoated kraft liner which can withstand high humidity conditions with minimal cockling or wrinkling.
    • This tape has a film carrier which can add dimensional stability to foams and other substrates and also make it easier to handle the tape during slitting and die-cutting.
    • The bond strength of 3M™ Laminating Adhesive 300LSE increases as a function of time and temperature, and has very high initial adhesion.

    Typical Applications: 

    • Foam attachment for electronic assemblies.
    • Low surface energy substrates.
    • Graphic attachment of high surface energy and low surface energy.
