Overview of Double Sided Repostionable Tape
3M™ 9415PC is part of 3M’s Repositionable Tape family—a series of engineered double-coated tapes designed for applications that require one or both sides to be easily removed, repositioned, or reused. Unlike standard double-coated tapes that form a permanent bond immediately, 9415PC allows for controlled adhesion strength between surfaces.
Its dual-adhesive system makes it a favorite in prototyping, display assembly, and removable labeling. The key differentiator? A high-tack adhesive on the faceside (the side exposed when the roll is unwound) and a low-tack, removable adhesive on the backside, covered by a liner.
Construction Details
-
Faceside Adhesive: 3M™ 400 high-tack acrylic adhesive – offers strong, permanent adhesion to papers, plastics, and metals.
-
Backside Adhesive: 3M™ 1000 low-tack acrylic adhesive – enables clean removability from many films, foils, and paper stocks without causing delamination.
-
Carrier: 1 mil (0.025 mm) clear polyester for excellent dimensional stability.
-
Liner: 58 lb natural poly-coated kraft paper liner.
-
Total Thickness: 2 mils (0.05 mm).
-
Color: Translucent.
This balanced construction allows the tape to maintain a professional finish while giving engineers control over how temporary or permanent the bond becomes.
Performance Characteristics
-
Adhesion to Steel:
-
Faceside (Permanent): ~50 oz/in (54 N/100 mm)
-
Backside (Removable): ~3 oz/in (5.4 N/100 mm)
-
-
Temperature Resistance: Up to 158 °F (70 °C) continuous exposure.
-
UV Resistance: Good.
-
Solvent Resistance: Fair.
This differential adhesion makes 9415PC particularly versatile in laminating applications—strong enough to hold permanently on one side, yet gentle enough to remove cleanly from the other.
Advantages
-
Allows multiple repositioning cycles on the low-tack side without residue.
-
Works with flexible materials like films, foils, and papers.
-
Enables two-stage bonding—temporary hold during assembly, permanent hold after positioning.
-
Clear construction maintains appearance when used on translucent or decorative materials.
-
Performs well on smooth or lightly textured surfaces.
Common Applications
-
Reclosable bags and envelopes
-
Book inserts or promotional item mounting
-
Temporary labeling or point-of-purchase displays
-
Removable foam gasketing
-
Temporary protection or holding materials during transport
-
Changeable graphics and advertisements
Because it removes cleanly from most surfaces, it’s often used in assembly processes that require part repositioning before final adhesion.
Application Guidelines
For best performance:
-
Apply between 70 °F–100 °F (21 °C–38 °C).
-
Surfaces must be clean, dry, and free of oils.
-
Use firm pressure to enhance adhesive contact.
-
Once applied, the tape can withstand colder conditions without losing bond integrity.
Why Choose 9415PC?
3M™ 9415PC occupies a unique space between permanent and removable bonding. It’s a go-to solution for engineers, converters, and product designers who need reliable hold strength coupled with adjustability. At NEDC, we often convert 9415PC into custom die-cut shapes, tabs, or roll widths for packaging, assembly, and prototyping applications—helping customers reduce setup time while maintaining precise alignment control.
Summary
3M™ 9415PC Repositionable Double-Sided Tape bridges the gap between flexibility and permanence. With a polyester carrier for stability, dual adhesives for differential bonding, and clean removability, it continues to be a top choice for dynamic or changeable applications.
If you need to test-fit components, hold materials temporarily, or design reclosable systems, 9415PC offers a proven and repeatable solution. NEDC can die-cut or laser cut these tapes to complete shapes, or laminated tapes.
