Genuine 3M VHB Tape 4910 | 40-mil Optically Clear Acrylic Foam Tape for Invisible Glass Bonding - STK
STK supplies Genuine 3M VHB Tape 4910, the industrial gold standard for high-strength, optically clear structural bonding. Featuring a 40-mil (1.0mm) solid, pure acrylic chemistry matrix, this transparent double-sided tape functions as both a heavy-duty structural adhesive and a crystal-clear seal. It is engineered specifically for high-surface-energy (HSE) substrates where an invisible bond line is mandatory, including glass, acrylic panels, polycarbonates, and polished metals.
The primary engineering hallmark of 3M VHB 4910 is its exceptional optical clarity, which allows light to pass through with near-zero refraction or distortion. This unique viscoelastic material distributes dynamic and static loads evenly across the joint, offering an alternative to mechanical fasteners and liquid adhesives in high-end architectural, commercial display, and electronic hardware assemblies.
Key Features & B2B Benefits
For manufacturing engineers and architectural project managers, 3M VHB 4910 delivers a highly predictable, visually seamless structural attachment method under demanding operational conditions:
Optically Clear Geometry
Provides 100% crystal-clear transparency. The dense, pure acrylic film creates an invisible bond line on glass and acrylic installations, preserving clean product lines and unobstructed views.
01
Anti-Yellowing UV Shield
Formulated to resist severe solar radiation and environmental exposure. The chemical structure ensures the clear foam maintains its original transparency over extended field service, resisting discoloration, clouding, or thermal degradation.
02
Seamless Architectural Aesthetics
Distributes stress uniformly across the entire length of the joined surfaces. It eliminates the need for mechanical fasteners such as rivets, screws, or weld lines, keeping clean architectural surfaces perfectly smooth and free of localized stress points.
03
Viscoelastic Energy Absorption
The 1.0mm solid acrylic core possesses high dynamic stress dissipation capabilities. It continuously absorbs wind loads, thermal expansion differentials, and high-frequency vibrations, maintaining a tight, flexible structural connection.

Primary High-Value Application Fields
Architectural Glass Bonding: Attaching glass panes to metal frames, sealing structural glass partitions, and mounting architectural skylight components where visible fasteners would disrupt aesthetics.
LED & Commercial Display Assemblies: Bonding transparent acrylic panels, protective glass fascias, and backlighting modules onto commercial digital signs, vending machine interfaces, and kiosk screens.
Electronic Touch Screen Lamination: Securing cover lenses, touch panel sensors, and protective bezels within consumer electronics, aerospace instrumentation, and medical control monitors.
Premium Signage & Lightbox Fabrication: Splicing clear plastic components, mounting translucent acrylic lettering, and sealing edge-lit LED profiles to ensure seamless light transmission.
B2B Custom Supply Power: Precision Slitting & Cleanroom Handling
High-end electronics and architectural glass lines require pristine, dust-free edges and exact roll dimensions to prevent bond-line blemishes. STK directly optimizes your materials pipeline:
• Precision Roll Slitting to the Millimeter:
We process genuine 3M™ VHB™ 4910 master logs using automated circular blade slitters, cutting rolls into the precise custom widths required by your frame or channel profiles (e.g., 6mm, 15mm, 45mm) with a strict tolerance of ±0.2mm.
• Precision Die-Cutting Services:
Send us your CAD or PDF drawings. STK utilizes advanced rotary and flatbed die-cutting systems to convert genuine 3M™ VHB™ 4910 into custom mounting pads, transparent bonding frames, sealing gaskets, spacer rings, and other intricate geometric components with high dimensional accuracy for automated assembly applications.
