74921 TESA SELF-ADHESIVE PROTECTION FILM - GLASS

Self-adhesive protection film for glass and other smooth surfaces

The Tesa 74921 Self-adhesive Protection Film – Glass is a thin, smooth PE film designed to protect large glass areas and other smooth surfaces during work on site. It offers reliable protection against dirt, concrete and paint splashes, dust and light mechanical stress such as minor scratches. The film is easy to apply and can be removed cleanly without adhesive residues for a limited period, helping to keep windows, frames and glass doors clean and reducing cleaning time after the job is finished.

FAQ

On which surfaces can this protection film be used?

It is designed for glass and other smooth, non-rough, sensitive surfaces such as windows, glass doors, mirrors and similar smooth substrates.

Is it suitable for rough or textured surfaces?

No, the product is not suitable for rough surfaces. For optimal performance it should be applied only on smooth substrates.

How long can the film remain on the surface without leaving residues?

On suitable surfaces and under recommended conditions, the film can be removed residue-free after up to 90 days.

Can the film be repositioned during application?

Yes, the film can be repositioned several times during installation, allowing corrections while aligning it on the surface.

Does it protect against water?

The film offers medium water resistance. It provides basic protection against splashes, but is not intended for continuous or heavy water exposure.

How resistant is it to tearing?

The product is not classified as tear-resistant, so it should be handled with care to avoid damage during application and removal.

What temperature range is recommended for application?

The recommended application temperature range is from -5 °C to 60 °C.

Does humidity affect performance?

The film has good humidity resistance and is suitable for use in environments where normal humidity fluctuations occur, provided storage and application guidelines are respected.

How should the rolls be stored?

Store the product away from direct sunlight, at 10 % to 70 % relative humidity and at temperatures between 5 °C and 30 °C to maintain optimal performance.
