3M has the

options to meet
your needs.
Packaging Options
*Scotch-Weld adhesive packaging availability can vary by product.
**Jet-melt adhesive sticks may require specific 3M Polygun™Applicators.
3M offers dispensing systems to
meet the most exacting fabrication
and assembly applications.
Check chart for substrates used in measuring strength.
Hot Melt Adhesives
For applications requiring cost-efficient bonding, sealing, potting
or encapsulating, 3M Jet-melt adhesives offer good strength and
elastic characteristics.
*Note: This technical information and data should be considered representative or typical only and should not be used for specification purposes.
With the ever-increasing sophistication of
electronics, you need the most dependable and
versatile methods for their fabrication and
assembly. 3MTM Scotch-WeldTM epoxies and Jet-melt TM
adhesives have the performance characteristics
that provide reliable bonds and seals for a broad
spectrum of applications. From hard disk drive
and printed circuit board fabrication
to cellular phone and computer assembly, our
adhesives can provide solutions that help
improve product performance while
streamlining assembly processes
and reducing material costs.
Electronic Grade (EG) Epoxies
For assembly of sophisticated electronics where outgassing
and corrosion of material bonds are a concern, our two-part
Electronic Grade (EG) epoxies are an excellent alternative to
mechanical fasteners and lower-grade adhesives. 3M Scotch-
Weld EG epoxies produce far lower contamination levels of
ionic and outgassing impurities than typical epoxy adhesives.
This makes 3M Scotch-Weld EG epoxies ideal for the
fabrication and assembly of critical components.
One-Part Epoxies
3M Scotch-Weld one-part epoxies provide superior structural
adhesive performance where durability, environmental resistance
and chemical resistance are essential. One-part epoxies also
eliminate mixing, weighing and work life limitations. What’s
more, they cure on demand when heat is applied, thereby
offering flexibility in processing.
Two-Part Epoxies
If structural performance is a priority, consider the many
solutions provided by 3M Scotch-Weld two-part epoxies.
They’re available in a wide range of formulations, performance
profiles and handling characteristics. Precision dispensing is
made easy with the 3M EPX™Applicator System. Duo-Pak™
cartridges also offer room temperature storage and long shelf
life for added convenience in many fabrication and assembly
operations.

Packaging Options
*Scotch-Weld adhesive packaging availability can vary by product.
**Jet-melt adhesive sticks may require specific 3M Polygun™Applicators.
3M offers dispensing systems to
meet the most exacting fabrication
and assembly applications.
Check chart for substrates used in measuring strength.
Hot Melt Adhesives
For applications requiring cost-efficient bonding, sealing, potting
or encapsulating, 3M Jet-melt adhesives offer good strength and
elastic characteristics.
*Note: This technical information and data should be considered representative or typical only and should not be used for specification purposes.
With the ever-increasing sophistication of
electronics, you need the most dependable and
versatile methods for their fabrication and
assembly. 3MTM Scotch-WeldTM epoxies and Jet-melt TM
adhesives have the performance characteristics
that provide reliable bonds and seals for a broad
spectrum of applications. From hard disk drive
and printed circuit board fabrication
to cellular phone and computer assembly, our
adhesives can provide solutions that help
improve product performance while
streamlining assembly processes
and reducing material costs.
Electronic Grade (EG) Epoxies
For assembly of sophisticated electronics where outgassing
and corrosion of material bonds are a concern, our two-part
Electronic Grade (EG) epoxies are an excellent alternative to
mechanical fasteners and lower-grade adhesives. 3M Scotch-
Weld EG epoxies produce far lower contamination levels of
ionic and outgassing impurities than typical epoxy adhesives.
This makes 3M Scotch-Weld EG epoxies ideal for the
fabrication and assembly of critical components.
One-Part Epoxies
3M Scotch-Weld one-part epoxies provide superior structural
adhesive performance where durability, environmental resistance
and chemical resistance are essential. One-part epoxies also
eliminate mixing, weighing and work life limitations. What’s
more, they cure on demand when heat is applied, thereby
offering flexibility in processing.
Two-Part Epoxies
If structural performance is a priority, consider the many
solutions provided by 3M Scotch-Weld two-part epoxies.
They’re available in a wide range of formulations, performance
profiles and handling characteristics. Precision dispensing is
made easy with the 3M EPX™Applicator System. Duo-Pak™
cartridges also offer room temperature storage and long shelf
life for added convenience in many fabrication and assembly
operations.

With the ever-increasing sophistication of
electronics, you need the most dependable and
versatile methods for their fabrication and
assembly. 3MTM Scotch-WeldTM epoxies and Jet-melt TM
adhesives have the performance characteristics
that provide reliable bonds and seals for a broad
spectrum of applications. From hard disk drive
and printed circuit board fabrication
to cellular phone and computer assembly, our
adhesives can provide solutions that help
improve product performance while
streamlining assembly processes
and reducing material costs.
Electronic Grade (EG) Epoxies
For assembly of sophisticated electronics where outgassing
and corrosion of material bonds are a concern, our two-part
Electronic Grade (EG) epoxies are an excellent alternative to
mechanical fasteners and lower-grade adhesives. 3M Scotch-
Weld EG epoxies produce far lower contamination levels of
ionic and outgassing impurities than typical epoxy adhesives.
This makes 3M Scotch-Weld EG epoxies ideal for the
fabrication and assembly of critical components.
One-Part Epoxies
3M Scotch-Weld one-part epoxies provide superior structural
adhesive performance where durability, environmental resistance
and chemical resistance are essential. One-part epoxies also
eliminate mixing, weighing and work life limitations. What’s
more, they cure on demand when heat is applied, thereby
offering flexibility in processing.
Two-Part Epoxies
If structural performance is a priority, consider the many
solutions provided by 3M Scotch-Weld two-part epoxies.
They’re available in a wide range of formulations, performance
profiles and handling characteristics. Precision dispensing is
made easy with the 3M EPX™Applicator System. Duo-Pak™
cartridges also offer room temperature storage and long shelf
life for added convenience in many fabrication and assembly
operations.
