**Remoistenable Tissue โ€” Transcript & Summary | SozAI** Source: https://sozai.app/transcript/remoistenable-tissue/ Learn how to make and use remoistenable tissues for paper conservation, ideal for moisture-sensitive objects. ## Key Takeaways - Remoistenable tissues provide a gentle method for repairing delicate paper without excessive moisture. - Proper adhesive selection and application technique are crucial for effective tissue performance. - Japanese paper is the preferred carrier for its compatibility and strength. - Using a polyester backing film helps in preparing and handling the tissue before application. - The method allows for quick drying and multiple tissue preparations. ## What the video covers - Remoistenable tissues stabilize or close tears in paper, especially for moisture-sensitive objects. - They consist of a carrier material coated with an adhesive that reactivates with minimal moisture or solvent. - Japanese papers are commonly used as carrier materials for these tissues. - Adhesive concentration typically ranges from 0.5% to 5%, depending on strength and thickness requirements. - Preparation involves applying adhesive on a polyester backing film and fixing it with weights or tape. - Three main adhesive application techniques are used: wide soft brush, film applicator, and pipet; airbrush is an alternative. - Hydroxypropyl cellulose and gelatin are examples of adhesives used in various concentrations. - The adhesive film should be even, bubble-free, and slightly larger than the paper substrate. - Remoistenable tissues dry quickly as adhesive only needs to dry on the surface, allowing multiple preparations. - These tissues are suitable for water-sensitive objects due to low moisture penetration. Answers ## Questions about this video What are remoistenable tissues used for in paper conservation? Remoistenable tissues are used to stabilize or close tears in paper, especially for objects that are sensitive to moisture. What materials are needed to make remoistenable tissues? You need a carrier material like Japanese paper, a selected adhesive such as hydroxypropyl cellulose or gelatin, a nonadhesive backing like polyester film, and weights or tape to hold it in place. How is the adhesive applied when making remoistenable tissues? Adhesive can be applied using a wide soft brush, a film applicator for uniform thickness, a pipet, or an airbrush, depending on the desired film thickness and adhesive concentration. ## Full Transcript โ€” Download SRT & Markdown 00:12 Speaker A This video explains what remoistenable tissues are, how they are made, and how they can be used in paper conservation. Remoistenable tissues are used to stabilize or close tears in the paper. They are particularly suitable for objects that are sensitive to moisture. 00:35 Speaker A moisture essentially a remoistenable tissue consists of a carrier material coated with an adhesive the adhesive layer is reactivated during use with a minimal amount of moisture or solvent a variety of Japanese papers can be used as a carrier material When selecting the 00:55 Speaker A Essentially, a remoistenable tissue consists of a carrier material coated with an adhesive. The adhesive layer is reactivated during use with a minimal amount of moisture or solvent. A variety of Japanese papers can be used as a carrier material. When selecting the adhesive, it is important to ensure that it can be reactivated with moisture or a solvent. When applied, the adhesive should form an even film without air bubbles. Depending on the requirements in terms of adhesive strength and film thickness, 01:11 Speaker A a concentration of between 0.5% and 5% is appropriate following supplies are needed a carrier material for example Japanese paper the selected adhesive and a nonadhesive backing such as polyester film and weights or tape to hold it in place in this video you will be shown 01:39 Speaker A a concentration of between 0.5% and 5% is appropriate. Following supplies are needed: a carrier material, for example Japanese paper, the selected adhesive, and a nonadhesive backing such as polyester film, and weights or tape to hold it in place. In this video, you will be shown 01:59 Speaker A the paper against the adhesive layer the preparation procedure entails applying the selected adhesive and fixing the base with weights or tape with a little practice you will also be able to fix the object by simply using your fingers the Japanese papers should be 02:19 Speaker A three different techniques for the application of the adhesive. For this, a wide and soft brush, a film applicator for a defined film thickness, and a pet are needed. As an alternative, an airbrush can be used. Last, a soft brush for pressing 02:45 Speaker A gelatin a film applicator can be used to achieve a uniform thickness of adhesive the adhesive is then applied with a pipet in this example we use a 2.5% hydroxypropyl cellulose using both hands pull the film applicator over the substrate in a 03:05 Speaker A the paper against the adhesive layer. The preparation procedure entails applying the selected adhesive and fixing the base with weights or tape. With a little practice, you will also be able to fix the object by simply using your fingers. The Japanese papers should be 03:26 Speaker A adhesive film should also be slightly larger than the paper substrate and should not contain any bubbles the paper substrate is held diagonally over two corners and placed on the adhesive film it will usually adhere to the adhesive film by itself if 03:44 Speaker A humidified beforehand. See this video for more information on paper humidification. To make the remoistenable tissue, the adhesive is brushed onto a polyester film. Then a soft brush is used to spread the adhesive evenly. In this example, we are using a 3% 04:03 Speaker A less the unevenness provides a larger contact surface between the adhesive and the object allowing a lower adhesive concentration to be selected after drying the remoistenable tissue is cut to size on the polyester film the remoistenable tissue is now 04:24 Speaker A gelatin. A film applicator can be used to achieve a uniform thickness of adhesive. The adhesive is then applied with a pipet. In this example, we use a 2.5% hydroxypropyl cellulose. Using both hands, pull the film applicator over the substrate in a 04:49 Speaker A adhesive should be applied relatively quickly to the corresponding area in this case since the adhesive is only reactivated on the surface and does not have to dry completely the drying time is much shorter as a result several remoistenable tissues can be prepared 05:09 Speaker A smooth, even motion. The adhesive can also be applied with an airbrush. In this example, we are using a 1% gelatin solution. After applying the adhesive, the spray head should be thoroughly cleaned to prevent the nozzles from sticking. The 05:33 Speaker A solvents due to the low moisture penetration remoistenable tissues are suitable for water sensitive objects [Music] Topics: remoistenable tissue paper conservation Japanese paper adhesive application hydroxypropyl cellulose gelatin adhesive paper repair moisture sensitive objects film applicator airbrush adhesive --- This is the markdown twin of https://sozai.app/transcript/remoistenable-tissue/ โ€” the same content, without the markup.
