Mounting and Trim Attachment
3M Mounting and Trim Attachment solutions hold strong and long for smarter designs
The perfect tools for stylish performance
Mounting and Trim Attachment is the application of a smaller object to a larger surface to add functionality or decoration. These kinds of attachments are common in transportation, appliances, furniture, construction and architecture. They often require dead load holding strength, aesthetics, removability and fast bonding with little or no fixturing.
-
-
Mounting Assembly
Examples include small signs, mirrors and white boards, and panel-over-panel with partial adhesive coverage.
-
Trim Attachment
Decoration or identification added to a surface. Examples included nameplates, edge banding, bezels, rosettes and muntin bars.

- Dead load holding strength
- Pleasing aesthetics
- Repositionability during application
- Fast rate of strength build
- Removability after cure
Shear Stress in Mounting and Trim Attachment Assemblies
-
-
Very similar to panel-to-frame and stiffener-to-panel assemblies, mounting and trim often experience dead load shear due to gravity. Because the joint is often already designed as shear it is an inherently preferable design for adhesive bonding. Some mounting applications, however, will also see some cleavage in addition to shear – and as an impact rather than dead load: consider lenses or housings mounted to portable electronics or cases. Dynamic stresses are very common and drop-tests may be performed to test adhesive or tape strength.
-
PRO TIP
When the application requires dynamic strength, designing the joint with a tongue-and-groove provides additional mechanical strength and stress dissipation upon impact. Structural adhesives can often be used for these applications to provide a permanent assembly.
Performance factors for mounting and fixing small parts
Industrial adhesives and tapes with the features below are best suited for mounting and fixing small parts:
- Dead load holding strength
- Enhances aesthetics
- Able to reposition during application
- Fast rate of strength build
- Requires little or no fixturing
- Removability after cure
