Adhesive transfer tapes provide a high-performance bonding solution without a carrier layer. They deliver maximum conformability for irregular surfaces and are widely used in manufacturing, assembly, graphics, and precision converting applications. If you need a thin, clean, pressure-sensitive adhesive with excellent wet-out on demanding substrates, ATT products offer a reliable alternative to mechanical fasteners and thicker double-coated tapes.
Why Choose Adhesive Transfer Tapes?
Adhesive transfer tapes consist of a uniform layer of pressure-sensitive adhesive coated onto a release liner. This construction creates unique advantages for engineers and manufacturers who require high bond strength in a thin profile.
Key benefits include:
-
Superior conformability for curved, textured, or low-profile assemblies.
-
Excellent wet-out on a wide range of substrates including metals, plastics, composites, and coated papers.
-
High shear strength and tensile performance compared to many double-coated or rubber-based adhesive systems.
-
Cleaner aesthetics and reduced material thickness for electronic, aerospace, and signage applications.
-
Ability to form strong, durable bonds without the bulk of a carrier film.
Common applications include nameplate bonding, gasket attachment, membrane switches, foam lamination, splicing, and precision die-cut components.
Technical Specifications
Performance varies by adhesive family, but typical attributes include:
• Temperature Resistance
Acrylic adhesive systems generally withstand continuous temperatures from 90°C to 150°C, with select high-performance grades exceeding this range. Rubber-based systems provide aggressive tack at room temperature but are less suitable for high-heat environments.
• Substrate Compatibility
ATTs bond effectively to:
-
High surface energy (HSE) metals and plastics including aluminium and stainless steel.
-
Many low surface energy (LSE) materials such as polyethylene, polypropylene, powder-coat, and textured plastics when using specialised acrylic formulations.
-
Coated papers, foils, foam, and composite substrates in converting applications.
• Indoor and Outdoor Performance
Acrylic adhesive transfer tapes provide UV resistance, solvent resistance, and long-term durability outdoors. Rubber adhesives should be reserved for indoor use due to limited weathering resistance.
• Thickness and Handling
Because there is no internal carrier, adhesive transfer tapes offer ultra-thin profiles ranging from 1–5 mil. The absence of structure requires careful handling during manual application, although manufacturers frequently add a fibre-reinforced liner for stability.
Application Guide
To achieve maximum bond strength:
-
Prepare the surface. Clean using IPA/water mix to remove oils, dust, and processing residue. Ensure the substrate is fully dry.
-
Apply firm pressure. ATT products rely on pressure to drive the adhesive into the substrate’s micro-texture. Use a roller or squeegee where possible.
-
Allow proper dwell time. Acrylic adhesives reach full cure after 24–72 hours, improving shear and peel strength.
-
Avoid stretching the adhesive. Because ATTs lack a carrier, excessive pulling can distort the adhesive during application.
-
Use alignment techniques. Tabs, fixtures, or temporary backers help prevent wrinkling or misalignment when applying larger pieces.
FAQs
Is adhesive transfer tape removable?
Most acrylic ATTs are permanent and designed for long-term bonding. Removable or repositionable versions exist but are less common and intended for temporary signage or low-tack applications.
Will this work on powder-coated metal?
Yes, but always choose a high-performance acrylic adhesive engineered for low surface energy coatings. Proper cleaning and firm application pressure are essential.
What is the difference between transfer tape and double-coated tape?
Transfer tape is pure adhesive on a liner. Double-coated tapes include a carrier material that provides dimensional stability and easier handling but reduces conformability.
Can adhesive transfer tapes be die-cut?
Yes. They are widely used in precision-cut components. However, the lack of a carrier means specialised liners and equipment improve cutting accuracy and handling.
