FIBER CLOTH TAPE AT0121

AT0121 RAYON CLOTH TAPE: High-Performance White Rayon Cloth Adhesive Tape

The AT0121 rayon cloth tape is a white rayon cloth adhesive tape designed for demanding applications where holding power and strength are non-negotiable.

Its rayon structure gives it excellent tear resistance, ideal for masking, strapping, or repairing in industrial environments.

The high-performance adhesive ensures reliable adhesion to a wide range of surfaces, even under sustained usage conditions.

What is the AT0121 Rayon Cloth Tape?

The AT0121 Rayon Cloth Tape is an adhesive tape with a rayon (fibranne) cloth backing, coated with a high-performance acrylic adhesive. Its white color makes it discreet and suitable for visible applications.

It tears easily by hand, both lengthwise and across. This saves concrete time on site or in the workshop.

Composition and structure of the white rayon cloth tape

The rayon (fibranne) backing is a woven synthetic textile, lighter than standard cotton cloth. It offers good mechanical strength while remaining flexible.

The tape structure consists of three layers:

• A white rayon cloth backing, resistant to tearing
• A high-cohesion acrylic adhesive
• An anchorage primer between the two for a durable bond

The acrylic adhesive guarantees good long-term hold, including when faced with moderate temperature variations. It does not leave a greasy residue on smooth surfaces.

Compared to a traditional cotton cloth tape, the AT0121 is more uniform in thickness and offers a more homogeneous surface, ideal for clean finishes or marker inscriptions.

Technical specifications of the AT0121 Rayon Cloth Tape

The AT0121 Rayon Cloth Tape is an adhesive tape with a white rayon (fibranne) cloth backing. It combines mechanical strength and flexibility to adapt to irregular surfaces.

Its natural rubber adhesive offers excellent initial tack on many substrates: cardboard, wood, plastic, metal. Adhesion is rapid and reliable, even in demanding usage conditions.

The rayon cloth gives the tape good hand-tear resistance without the need for cutting tools. This is a concrete advantage on construction sites or in production, where application speed matters.

Key features:

• Backing: rayon cloth
• Color: white
• Adhesive: natural rubber
• Hand-tearable
• Good conformability on curved surfaces
• Mainly for indoor use

Application areas for the AT0121 Rayon Cloth Tape

The AT0121 Rayon Cloth Tape is a versatile adhesive tape designed to meet the requirements of professional and industrial environments. Its white rayon cloth gives it good mechanical strength while remaining easy to tear by hand.

Industrial and professional uses

This tape is used in many sectors. It is particularly suitable for temporary masking, holding, bundling cable harnesses, or surface protection.

Here are the main application areas:

• Cabling and electrotechnics: holding and bundling cables and harnesses
• Industrial packaging: reinforcing and sealing heavy parcels
• Construction and finishing: temporary fastening, zone marking, surface protection
• Automotive industry: wrapping and protecting electrical harnesses
• General maintenance: temporary repairs on equipment and structures

The white rayon cloth offers a clean and neutral appearance, making it a common choice in environments where visual presentation matters, such as exposed electrical installations.

Its ability to be torn manually without tools facilitates rapid application on sites or in workshops. It is a concrete asset for professionals working in real-world conditions.

Comparison: AT0121 vs. other cloth tapes in the AT range

AT0121, AT0180, AT6200, AT2002: what are the differences?

The AT range includes several cloth tapes with very distinct profiles. Here is how the AT0121 compares to its counterparts.

Part Number	Backing	Color	Adhesive	Main use	Strength
AT0121	Rayon cloth	White	Natural rubber	Masking, finishing, marking	Clean manual tear, smooth white surface
AT0180	Rayon cloth	Black	Natural rubber	Cabling, light insulation, marking	Visual discretion, good contrast on light backgrounds
AT6200	Woven polyester cloth	Grey / Silver	Synthetic rubber	Repair, harness wrapping	Superior mechanical strength, increased heat resistance
AT2002	Cotton cloth	White	Natural rubber	Packaging, protection, general use	Maximum flexibility, very good conformability

The AT0121 with white rayon cloth stands out for its smooth surface and neat appearance. It is perfectly suited for applications where visual cleanliness counts as much as holding power.

Compared to the AT6200, it falls behind in mechanical strength. However, it is easier to tear by hand and leaves a neat finish without tools.

Compared to the AT2002 cotton tape, the AT0121 rayon backing offers a more homogeneous surface and better dimensional stability. Cotton remains more flexible, but less uniform.

The AT0180 shares the same construction as the AT0121, only the color changes. The choice between the two depends solely on the visual context of the application.

Instructions for use and application of the AT0121 Rayon Cloth Tape

The AT0121 Rayon Cloth Tape is easy to apply, but a few best practices will help you get the best out of it.

Start by cleaning and drying the surface before application. Dust, grease, or residual moisture reduce adhesion. A dry cloth is sufficient in most cases.

Apply the tape by pressing firmly with your palm or an application roller. Press along the edges to prevent any premature peeling.

The white rayon cloth cuts easily by hand in the direction of the weave. No need for a cutter for most common uses.

For temporary assemblies or repairs, the tape can be removed without leaving residue if removed quickly after application. On delicate surfaces, test on a small area first.

This tape is suited for indoor environments. For prolonged exposure to moisture or UV, opt for an aluminum tape or reinforced PVC tape.

• Clean and dry surface before application
• Firm pressure along the entire length
• Hand-cutting possible
• Prior test on sensitive surfaces
• Recommended for indoor use

FAQ - AT0121 Rayon Cloth Tape

1. What is rayon and why is it used in this tape?

Rayon is a textile fiber derived from regenerated cellulose, similar to viscose. It gives the tape a natural flexibility and good resistance to manual tearing.

This is what allows the AT0121 cloth tape to be cut by hand, without scissors, while maintaining a solid hold once applied.

2. On which surfaces does the AT0121 tape adhere properly?

It adheres to most clean and dry surfaces: cardboard, wood, metal, rigid plastic, and some textiles.

Dusty, damp, or highly porous surfaces reduce holding power. A quick wipe usually corrects the problem.

3. Is the AT0121 tape moisture-resistant?

The white rayon cloth offers moderate resistance to occasional moisture. It is not designed for immersion or prolonged exposure to water.

For very damp environments, a PVC or polyester tape will be more suitable.

4. Can you write or print on this tape?

Yes. The matte white surface of the rayon accepts permanent marker well. This is a concrete advantage for marking, labeling, or temporary signage.

However, direct industrial printing is not well-suited to this type of textile backing.

5. What is the difference between rayon cloth tape and classic duct tape?

A classic cloth tape (duct tape) often uses a woven polyester or polyethylene backing, which is more rigid and more waterproof.

Rayon provides a softer feel, a cleaner hand-tear, and better breathability, useful for masking or light holding.

6. Does the AT0121 tape leave residue when removed?

When removed quickly and under good conditions, it leaves little or no residue on most smooth surfaces.

On sensitive surfaces (fresh paint, varnished wood), it is advisable to perform a preliminary test and remove the tape by pulling at a 45° angle, slowly.
