Technical Data November 2011 3M Double Coated Tapes 9474LE 9495LE Product Description 3M Double Coated Tapes with 3M Laminating Adhesive 300LSE provides high bond strength to most surfaces, including many low surface energy plastics such as polypropylene and powder coated paints. The acrylic adhesive also provides excellent adhesion to surfaces contaminated lightly with oil typically used with machine parts.

Note 2: Backside (BS) adhesive is on the exterior of the roll, exposed when liner is removed. Note 3: The caliper listed is based on a calculation from manufacturing controlled adhesive coat weights using a density of 1.012 g/cc. Features This tape has a film carrier which can add dimensional stability to foams and other substrates and also makes it easier to handle the tape during slitting and die-cutting. 3M Double Coated Tape 9474LE features a dual liner for ease in selective die cutting. The bond strength of 3M Laminating Adhesive 300LSE increases as a function of time and temperature, and has very high initial adhesion. Application Ideas Foam to powder coated painted surfaces. Low surface energy plastic adhesion. Lens bonding applications. 3 3M Double Coated Tapes 9474LE 9495LE Typical Physical Properties and Performance Characteristics Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.
