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 1: Faceside (FS) adhesive is on the interior of the roll, exposed when unwound.
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.
