    L1
    The L1 adhesive platform features a modified acrylic adhesive with good initial tack and peel adhesion. 3M™ Tape L1 Series are designed to withstand temperatures up to 93°C (200°F) and bonds well to a wide range of substrates, including PU ether, cross-linked PE foam and microcellular urethane. All L1 constructions feature 74# white, unprinted, densified kraft liner for excellent processing.
    L1 + DCP - Double coated tape
    L1 + RT - Scrim reinforced tape

    L1 + DCP
    • This 3.5-mil double-coated polyester tape provides added dimensional stability and ease of handling during laminating or die cutting, particularly on thin or flexible susbtrates.

    • Adhesive coat weight of 1.5 mils each side of a 0.5-mil PET carrier provides good adhesion to many substrates.

    L1 + RT
    • 3M™ L1 + RT Adhesive Transfer Tape is reinforced with a high density scrim carrier to boost dimensional stability during lamination.

    • An adhesive coat weight of 3.2-mils allows the adhesive to flow and ensures good bond strength even around tight radiuses and contoured surfaces.

  • L2
    The L2 adhesive platform features a proprietary 3M modified acrylic that withstands temperatures up to 107°C (225°F) and offers high initial tack, excellent peel adhesion and shear strength to many open and closed cell foams. It bonds well to PU ether, cross-linked PE foam, EPDM foam, neoprene foam, nitrile foam and microcellular urethane.

    All L2 constructions feature an 83# tan coloured, unprinted polycoated kraft liner.
    L2 + DCP - Double coated tape
    L2 + DCD - Double coated differential tape
    L2 + T3 - Adhesive transfer
    L2 + T5 - Adhesive transfer

    L2 + DCP
    • This double-coated polyester tape provides excellent adhesion to a wide variety of substrates, including many open and closed cell foams.

    • A thin 0.5-mil PET carrier provides enhanced dimensional stability, handling and easy processing.

    L2 + DCD
    • This double-coated differential tape adheres well to open and closed cell foams (L2 adhesive face side) and low surface energy materials (LSE acrylic adhesive on backside).

    • Excellent for bonding both open and closed cell foams to LSE materials.

    L2 + T3
    • This 3-mil transfer tape does not have a carrier, which enables it to provide maximum confromability and good adhesion to opena nd closed cell foam surfaces.

    L2 + T5
    • This 5-mil transfer tape shares the benefits of L2 + T3 but offers a thick coat weight to adhere to the most structured open and closed cell foam surface.

  • L1
    The L3 adhesive platform is a proprietary specialty acrylic adhesive designed to withstand temperatures up to 135°C (275°F) and has good adhesion to many elastomeric substrates. It bonds well to santropene, neoprene rubber, butyl rubber and many versions of EPDM rubber. All L3 constructions feature an 83# tan coloured, unprinted polycoated kraft liner for superior processing.
    L3 + T3 - Adhesive transfer tape
    L3 + T5 - Adhesive transfer tape

    L3 + T3
    • This 3-mil transfer tape does not have a carrier, which enables it to provide maximum conformability and good adhesion to elastomeric surfaces.

    • Adhesive coat weight of 1.5 mils each side of a 0.5-mil PET carrier provides good adhesion to many substrates.

    L3 + T5
    • This 5-mil transfer tape shares the benefits of L3 + T3, but offers a thick coat weight to adhere to more structured surfaces.
