Demonstrated versatility and bonding strength is

what’s behind the brand name “Scotch-Weld”.

The name is based on aircraft company

conclusions made in the early 1950’s that

this class of 3M load-bearing adhesive

exhibited assembly strength comparable to

welding. Today, industries worldwide take

advantage of the reliability and wide selection

of 3M

Structural Adhesives

for a variety of challenging applications.

The tools in the Demonstration Kit provide

tangible evidence of the history of

Scotch-Weld high performance on a wide

variety of substrates. To better understand

performance on different substrates, the

following information presents characteristics

and benefits of representative adhesives.

When used with the 3M

Structural Adhesives Selection Guide, this

kit can help an engineer or product designer

gain confidence in 3M structural adhesives

and choose products for evaluation.

Instant

Adhesive CA-40

• Cyanoacrylate adhesive for gaskets and

quick repairs

• Quickly bond most rubber, including

difficult-to-bond EPDM

• Fast set increases productivity

Bond EPDM to aluminum disk. CA-40 also

bonds EPDM to other bare or painted metal with

strength greater than the EPDM. This means that

with enough peel stress at the edge of the bond,

the EPDM itself will tear apart. Rather than

demonstrate this and destroy the tool, the photo

here shows delamination.

• 2-part epoxy adhesive

bonds most substrates

• Room cures to over 4000 PSI in overlap

shear strength

• Unique toughened formula for

impact resistance

Structural

Plastic Adhesive DP-8010

• 2-part acrylic adhesive bonds to

polyethylene and polypropylene with no

surface preparation

• Tough bond strength to resist vibration

and impact

• Bonds most difficult-to-bond LSE (low

surface energy) plastics

Polyethylene pipe bonded to polypropylene pipe in a straight butt joint for non-potable water and

liquids. This type of joint would generally not be used because of a high potential to fail under stress. But

for purposes of demonstration, this tool demonstrates the adhesives ability to not only hold the joint but

also permanently bond dissimilar difficult-to-bond plastics. Try bending and torquing the assembly by hand.
