What is Pressure Sensitive Tape?
Pressure sensitive tape, also known as adhesive tape, is a type of tape that adheres to a surface when pressure is applied. It is commonly used for various applications such as packaging, labeling, and repairing.
Pressure sensitive tape is made up of a backing material, adhesive, and a release liner. The adhesive is activated by applying pressure, which allows the tape to stick to a surface without the need for heat or solvent activation.
History of Pressure Sensitive Tape in Art Conservation
The use of pressure sensitive tape in art conservation dates back to the mid-20th century. Initially, pressure sensitive tapes were used as a quick and convenient way to repair tears and hold together fragile artworks.
However, over time, it became evident that the adhesive in pressure sensitive tape could cause irreversible damage to artworks. Conservators began to explore alternative methods for repairing and restoring art without the use of pressure sensitive tape.
Types of Pressure Sensitive Tape Used in Art Conservation
There are several types of pressure sensitive tape that are commonly used in art conservation. These include:
1. Acid-free tape: This type of tape is made from materials that are pH neutral and will not cause damage to the artwork over time.
2. Japanese paper tape: Japanese paper tape is a thin, strong tape that is often used in delicate art restoration projects.
3. Filmoplast tape: Filmoplast tape is a transparent tape that is commonly used for repairing tears in paper artworks.
Application of Pressure Sensitive Tape in Art Restoration
Pressure sensitive tape is often used in art restoration to repair tears, hold together fragile artworks, and mount artworks for display. However, conservators must be cautious when using pressure sensitive tape, as the adhesive can cause irreversible damage to the artwork over time.
When applying pressure sensitive tape to an artwork, conservators must ensure that the tape is acid-free, archival quality, and easily reversible. It is also important to test the tape on a small, inconspicuous area of the artwork before applying it to the entire piece.
Risks and Considerations When Using Pressure Sensitive Tape in Art Conservation
There are several risks and considerations that conservators must take into account when using pressure sensitive tape in art conservation. These include:
1. Adhesive residue: Over time, the adhesive in pressure sensitive tape can degrade and leave behind a sticky residue that is difficult to remove without causing damage to the artwork.
2. Yellowing: Some types of pressure sensitive tape can yellow over time, causing discoloration to the artwork.
3. Incompatibility with artwork materials: The adhesive in pressure sensitive tape may not be compatible with certain types of artwork materials, causing damage or deterioration over time.
Alternatives to Pressure Sensitive Tape in Art Restoration
Due to the risks associated with pressure sensitive tape, conservators have developed alternative methods for repairing and restoring art. Some alternatives to pressure sensitive tape include:
1. Wheat starch paste: Wheat starch paste is a traditional adhesive that is commonly used in art restoration. It is reversible, pH neutral, and does not cause damage to artwork over time.
2. Japanese tissue paper: Japanese tissue paper is often used in conjunction with wheat starch paste to repair tears and reinforce fragile artworks.
In conclusion, while pressure sensitive tape can be a convenient tool for art restoration, conservators must be cautious when using it to avoid causing irreversible damage to artworks. By exploring alternative methods and materials, conservators can effectively repair and restore art while preserving its integrity for future generations.
