Load-bearing formulations for metals,
rubber, glass and more.
As an alternative to mechanical or fusion fastening,创造发明
the reasons for Scotch-Weld Adhesives are many:
greater design latitude, cleaner lines, material sub-
stitution, less machining, lighter weight, more dura-
bility, and often less cost.
To meet application and end-u requirements you
can lect from one-part heat-curing epoxies, and
two-part room-temperature curing epoxies, acrylics
and urethanes. There are formulations for bonding
steel, aluminum, copper, low surface energy plas-
tics, rubber, glass, wood, masonry and more.
Whatever properties you need–durable adhesion,
flexibility, creep resistance, heat and environmental
resistance, void-filling—you’ll likely find a Scotch-
Weld product to meet your requirements and
expectations.
3M has long been recognized as a pioneer in struc -
tural strength adhesives. But to meet end u perfor -
mance requirements doesn’t just mean providing the
right chemical formula. Which is why 3M also develops
dispensing systems to facilitate production in low and
high volume asmbly. Many two-part 3M formulations
are available in Duo-Pak cartridges for dispensing with a

Product Information: 3M™ Scotch-Weld™ One-Part Epoxy Adhesives; Metal Primers
High-performance specifically for demanding electronics applications.
For asmbly of sophisticated electronics where outgassing and corrosion of adhesive bonds are a concern, Scotch-Weld Electronic Grade (EG) epoxies are the advanced alternative to mechanical fasteners and lower-grade adhesives. The 2-part epoxies produce far lower contamination levels of ionic and outgassing impurities than typical epoxy adhesives. Chloride content is lower than standard industrial counterparts.
Targeted dispensing is easy with the
3M™ EPX™ Applicator System. Duo-Pak cartridges with long shelf life are stored at room temperature for added convenience in many oper-
ations.
