Double-sided tape 3M 91915025 — 50 mm x 25 m, acrylic adhesive

3M double-sided tape 91915025 is a 50 mm wide, 25 m long acrylic adhesive tape designed for permanent bonding applications. The thin, double-coated construction provides a discreet joining solution for a variety of materials, delivering consistent hold where a low-profile bond is needed. This tape is formulated to perform in industrial, workshop and household environments, offering reliable adhesion to metals, plastics, glass, painted surfaces and laminates.

Advantages

The acrylic adhesive offers strong initial tack and long-term shear strength, with good resistance to temperature and ageing. The tape’s thin carrier minimizes the visible joint and provides a flush finish between adhered surfaces. Its double-sided nature simplifies mounting and laminating tasks by eliminating mechanical fasteners and visible fixings. Suitable for permanent applications, the adhesive maintains stability over time under normal environmental conditions.

Suitable for

• Mounting trim, nameplates and signs
• Bonding metal, plastic and glass components
• Laminating thin panels and overlays
• Workshop and general-purpose fastening where a low-profile bond is desirable
• Assembly tasks in industrial or light-manufacturing settings

Key specifications

• Width: 50 mm
• Length: 25 m
• Adhesive type: acrylic
• Double-sided construction for concealed bonds
• Suitable for long-term permanent bonding
• Compatible with metals, plastics, glass, painted surfaces and laminates

How to use

Clean and dry both bonding surfaces to remove dust, oil and other contaminants; use an appropriate solvent if necessary and allow full evaporation. Measure and cut the tape to the required length, apply pressure evenly across the bonded area to ensure full contact, and allow the adhesive to develop maximum strength according to the substrate type. For best results, apply at recommended application temperatures and avoid movement of bonded parts until the adhesive has set.

Usage recommendations

For optimal adhesion, press firmly across the tape with a roller or similar tool to eliminate air gaps. Avoid applying the tape to rough, dirty or highly curved surfaces without prior surface preparation. When bonding low-energy plastics, test compatibility first or prepare the surface with an appropriate primer.
