Authentic Tesa Quality – What to Look For

Tesa 4965 is a flagship double coated tape trusted by manufacturers worldwide. To ensure you receive genuine performance, always look for the official Tesa-branded core and full-length rolls.

Be cautious of unbranded or blank cores and shorter rolls that may be offered online. These products may not meet the same specifications, consistency, or long-term reliability as authentic Tesa 4965 double coated tape.

Additional Information

Tesa 4965 is part of the Tesa family of high-performance, double coated tapes designed to replace mechanical fasteners and liquid adhesives in many applications. Its combination of transparent PET film, tackified acrylic adhesive, and proven reliability makes it an excellent choice for bonding smooth, rigid, and high-energy surfaces.

For best results, ensure surfaces are clean, dry, and free from dust, oil, or release agents before application. Apply firm pressure to achieve full wet-out of the adhesive. Where long-term or critical bonding is involved, sampling the tape in your specific application is always recommended before full production.
