Double-sided tape 3M 5925F VHB dark gray 12 x 0.64 mm, 33 m roll

3M 5925F VHB double-sided tape in dark gray is a thin, high-strength foam adhesive designed for permanent bonding applications. With a 12 mm width, 0.64 mm thickness and a 33 m roll length, this tape offers a balance of conformability and structural adhesion for joining metals, plastics and painted or coated surfaces. Its closed-cell acrylic foam core provides gap-filling capability and resistance to shear forces, while the dark gray carrier minimizes visibility on darker substrates. The product is suitable where a clean, fast assembly is required without mechanical fasteners.

Advantages

The acrylic foam construction delivers strong, durable bonds with good resistance to temperature variation, moisture and plasticizer migration from substrates. The tape’s thin profile allows for discrete joints and efficient use of space, while its conformability enables reliable contact across uneven or slightly irregular surfaces. It dampens vibration and absorbs stress, reducing the need for mechanical fasteners in many permanent mounting tasks.

Suitable for

• Mounting metal and plastic panels
• Attaching trims, nameplates and signage
• Bonding painted or coated surfaces
• Permanent joins where a low-profile adhesive is required

Key specifications

• Color: dark gray
• Width: 12 mm
• Thickness: 0.64 mm
• Roll length: 33 m
• Core material: closed-cell acrylic foam
• Adhesion type: double-sided pressure-sensitive adhesive

How to use

Select and clean both bonding surfaces to remove dust, oils and release agents; use isopropyl alcohol or a compatible cleaner and allow surfaces to dry. Cut the tape to the required length, apply firm pressure to ensure full contact, and allow time for the adhesive to develop initial bond strength. For thinner or flexible parts, apply continuous firm pressure across the joint; for heavier assemblies, support parts until full adhesive strength is achieved. Avoid stretching the tape during application to maintain consistent bond thickness.

Usage recommendations

For optimal long-term performance, apply at recommended application temperatures and ensure substrates are compatible with acrylic adhesives. Use primer when bonding low-energy plastics or when enhanced adhesion is required. Store rolls in a cool, dry place away from direct sunlight and use within the manufacturer’s suggested shelf life.
