TESA Double-Sided Tape, 19mm x 50m, Transparent (64621)

The TESA 64621 is a high-performance double-sided filmic tape with a synthetic rubber adhesive, designed for permanent bonding applications. With a width of 19 mm and a length of 50 m, this transparent tape offers excellent adhesion to a variety of surfaces, including steel, plastics, and paper. The carrier material is a transparent polypropylene (PP) film, providing good tensile strength and elongation. The tape is equipped with a siliconized brown paper liner for easy handling and application. It is suitable for indoor use, offering good resistance to humidity and chemicals, but low UV resistance. Ideal for mounting, splicing, and general fixing tasks where a strong, invisible bond is required.

Advantages

This double-sided tape provides a strong and durable bond with high initial tack. The synthetic rubber adhesive ensures reliable adhesion on many surfaces, while the PP film carrier adds stability. The transparent color makes it nearly invisible when applied, perfect for clear or light-colored materials. The tape is easy to handle and cut, and the siliconized liner prevents unwanted sticking during application.

Suitable for

• Mounting of signs, posters, and displays
• Splicing of paper, films, and foils
• Bonding of plastic parts and components
• General fixing and holding applications in packaging and assembly
