STK Tape manufactures a premium Clear VHB (Clear Acrylic Foam Tape) engineered as a high-performance, cost-effective alternative to 3M 4905 and 3M 4910.
Featuring a solid, highly transparent acrylic structure, this Clear VHB tape provides an virtually invisible structural bond between smooth glass, clear acrylics, polycarbonates, and metals. Available in standard 0.5mm thickness (equivalent to 3M 4905) and 1.0mm thickness (equivalent to 3M 4910), it distributes dynamic stress along the entire length of the bond line while sealing against moisture and environmental elements. STK Tape provides global industrial manufacturers and display fabricators with flexible converting formats, custom roll dimensions, and precise die-cutting capabilities. Samples are available upon request for optical clarity evaluation and structural bonding tests prior to mass production.
Performance Features
Crystal-Clear Optical Transparency: Solid viscoelastic acrylic structure provides 100% transparent bond lines, making it ideal for glass-to-glass and backlit acrylic applications where visible adhesive lines are unacceptable.
Dual Thickness Engineering (0.5mm & 1.0mm): Offers 0.5mm gauge for ultra-thin precision electronic overlays and 1.0mm gauge for heavy architectural glass and gap-filling applications.
Viscoelastic Stress Dissipation: Allows the tape to stretch and absorb dynamic energy, compensating for differential thermal expansion between dissimilar substrates (such as aluminum to glass).
Permanent Weatherproof Sealing: Forms a continuous barrier against moisture, rain, dust, UV exposure, and industrial chemicals, preventing joint corrosion over long-term outdoor exposure.
Noise & Vibration Dampening: Replaces screws and rivets while absorbing structural vibrations, eliminating noise in display cabinets and architectural fixtures.

Application
STK Tape manufactures this advanced Clear VHB tape for high-aesthetic structural bonding across signmaking, glass construction, electronics, and architectural processing:
- Glass & Transparent Panel Bonding: Ideal for joining glass-to-glass, clear acrylic signage, glass display cabinets, and illuminated push-through lettering.
- Architectural & Commercial Glazing: Used for mounting decorative glass panels, partition walls, window trim, and skylight assemblies.
- Electronic Display & Appliance Trim: Secures transparent LCD windows, touch panels, and decorative glass facings in appliances and consumer electronics.
- Skylights & Lighted Signage Assembly: Permanent attachment of translucent panels and light-diffusing sheets where visible fasteners would mar appearance.
- Custom Die-Cut Structural Components: Easily converted into custom rings, frames, and intricate technical shapes for automated OEM assembly.
Solid clear acrylic VHB tapes present distinct converting challenges due to their soft, stretchy viscoelastic nature. STK Tape provides specialized converting solutions tailored specifically for solid clear acrylic mass:
Tension-Controlled Anti-Stretch Slitting: Micro-slitting performed under precise web-tension controls prevents edge distortion, roll telescoping, and sidewall adhesive bleeding on slit rolls.
Non-Stick Zero-Deformation Die-Cutting: Precision converting into frame gaskets, rings, and custom geometries using non-stick fluoropolymer tooling to eliminate edge compression and tape stringing.
Extended Finger-Lift Pull Tabs: Fitted with oversized or split red PE liners, allowing assembly line workers to peel thick 0.5mm and 1.0mm VHB liners effortlessly without stretching the adhesive edge.
Custom Gauge & Spool Options: Capability to supply custom thickness variations between 0.5mm and 1.0mm, as well as continuous spool-wound rolls for high-volume automated tape placement.
Global Lead Times
Industrial Packaging
STK Clear VHB Tape is supplied in log rolls, custom-slit narrow rolls, or precision die-cut parts on sheets. Packed with anti-static side discs and moisture-proof wrapping to prevent roll-end fusion during long-distance ocean transport.
Standard Dispatches
Standard 0.5mm and 1.0mm stock configurations in popular widths (12mm, 19mm, 25mm) are maintained for rapid dispatch based on order volume.
Custom OEM Slitting Orders
Custom roll widths, specialized spool configurations, and technical die-cut shapes are produced to client drawings. Lead times are confirmed upon drawing approval and quantity sign-off.
Important: STK's Clear VHB Tape is independently developed and manufactured by STK Tape. References to 3M 4905 and 3M 4910 are used strictly for comparative product positioning and application alignment. This product is not manufactured, sponsored, or endorsed by 3M Company. Customers are advised to test and validate performance under specific application conditions prior to mass production.
