Description
Item 9474-24x36-3pk is as pack of three sheets of 3M 9474LE double-linered* and double-coated**
adhesive transfer tape (or "double-sides adhesive," in layman's terms),
which features 3M's super-strong 300LSE adhesive. Each of the three sheets is of size 24" x 36" (612 mm x 918 mm), the original size as manufactured by 3M.
3M 300LSE adhesive bonds extremely well with metal, wood, plastics,
(even Acrylic and other so-called "low surface energy" plastics that
don't bond well with other glues), hard leather, suede, fabrics, rubber,
and, beware, your fingers. As illustrated in Fig. 2, there are two
adhesive layers, 2.8 mils and 3.4 mils thick, and between them is a thin
polyester carrier 0.5 mils thick. With this design the product is
suitable not only for smooth surfaces but also for lightly textured
and/or lightly porous surfaces. The third illustration above is a
comparison chart published by 3M that shows how the 300LSE adhesive
compares to other 3M double-sided adhesives with regard to adhesion to
different materials. As is apparent from that comparison table 3M's
300LSE adhesive is the strongest and most versatile adhesive
commercially available. For example, a very narrow sliver of 3M 300LSE
adhesive is used to bond the screen of the iTouch 4th Gen iPod Touch to
the body of the device. This adhesive is strong!
Included with purchase:
- Three sheets of 3M 9474LE 300LSE double-sided adhesive of size 24" x 36" (612 mm x 918 mm).
- One page choke-full of detailed instructions. We wrote this page specifically for this product and it aimed at less experienced users. Even if you could find this product elsewhere (and you won't), the instructions will help prevent you from ruining sheets and will reduce your learning curve from hours to the five minutes it takes to read the instructions.

Why 3M 9474LE is the best double-sided adhesive:
3M 9474LE is hands-down 3M's best
double-sided 300LSE adhesive, and here is why. Simpler versions of double-sided adhesive based on 300LSE (e.g., 3M's 8153LE) have
three layers: two protective liners, and sandwiched between them, the
300LSE adhesive. The problem with all versions offered with this 3-layer
design is that when cutting these sheets with scissors or knifes, a
small amount of the adhesive oozes out between the two liners and sticks
to the sides of the liners, along the cut. Then, when trying to peel
off a liner, that liner will stick to the opposite liner, making it
impossible to separate the liners cleanly. In contrast, the
sophisticated 9474LE product is constructed with five layers, as shown
in Fig. 2, above. Here, an ultrathin, so-called "carrier" is sandwiched
between two layers of 300LSE adhesive, thereby stabilizing the adhesive
and preventing it from oozing out when being cut. As a result, the
sheets of 3M 9474LE offered in this listing here can be cut with
utility knifes or scissors and the liners will separate cleanly without
sticking together. If you ever went through the frustrating
experience of cutting simpler versions of 300LSE-based double-sided
adhesives, you will appreciate the value of the 9474LE product. We here
at Soles2dance certainly appreciate the benefits of 3M 9474LE and we use
this sophisticated product for our own fabrication needs, even though
it is more expensive than simpler versions.3M
offers other double-coated** adhesive transfer tapes with the same
5-layer construction as that of 9474LE. However, in these other products
the adhesive layers on each side the carrier are not the same. For
example, 3M 9490LE uses
300MP adhesive on the faceside and 300LSE adhesive on the backside. This
is good for specific applications in the auto industry, but most of our
customers will prefer 300LSE on both sides, and the product
offered here is the only such version available as sheets. Also, in
small quantities of a few sheets and in small sizes (smaller than
24"x36"), this product is available only from us; take our word for it,
it will save you a lot of time.
Shipping notes:
- Our
store-wide offers for various free shipping options do not apply to this
product. Rather, there is a shipping cost for this item and we reserve the right to use at our discretion USPS Priority Mail or Amazon's multi-channel fulfillment shipping. The latter option means that the product ships from our
large stock of products stored at Amazon warehouses across the country,
using Amazon's reliable and fast shipping service. Typically, this
method of shipping gets the order into the customer's hands faster than
when we ship from our own warehouse.
- This item cannot be shipped outside of the U.S.
Other notes:
* "double-linered"
means that the product is provided with liners (protective foils) on
the front and back. This is different from products fabricated in the
form of rolls: those have only one liner and are thus not suitable for
marketing in sheet-format.
**
"double-coated"
means that there are two layers of adhesive, stabilized by a thin
polyester carrier between them. The adhesive layers on both sides of the
carrier adhere very strongly to that polyester carrier, giving the
combination of adhesive-carrier-adhesive the characteristics of a single
solid but flexible layer. Without the carrier, a single layer of
adhesive has the characteristics of a very viscous fluid, somewhat
similar to those of honey.
