Nanorestore Gel® Peggy

Overview

Nanorestore Gels® Peggy are hydrogel for cleaning and/or controlled humidification of surfaces. Thanks to their retentive network, the liquid contained in them is slowly released to the surface. Nanorestore Gel® Peggy are highly flexibile and elastic, allowing for the application even on rough and/or irregular surfaces. Nanorestore Gel® Peggy are sold loaded with water, but they can be also loaded with hydroalcoholic mixtures or water-based nanostructured fluids of the Nanorestore Cleaning® series.

Available Formulations
Nanorestore Gel®
Peggy 5
Opalescent hydrogel based on poly (vinyl alcohol) polymeric network. The gel, flexible and elastic, adheres well even on rough and irregular surfaces. Each package contains a water-loaded sheet (approx. 10 cm x 15 cm x 2 mm), which can be reused up to 5 times, depending on the specific case. 15 €
Nanorestore Gel®
Peggy 6
Opalescent hydrogel based on poly (vinyl alcohol) polymeric network. The Peggy 6 gel is even more flexible, elastic, having lower retention of loaded liquid than Peggy 5; this is why it adheres particularly well to very rough and irregular surfaces. Each package contains a water-loaded sheet (approx. 10 cm x 15 cm x 2 mm), which can be reused up to 5 times, depending on the specific case. 15 €
Nanorestore Gel®
Peggy 5 Gum
Opalescent hydrogel based on poly (vinyl alcohol) polymeric network. The gel is supplied in parallelepiped shape (approx. 12 cm3). It allows to associate controlled and localized humidification with a light mechanical action and can be used as a sort of ultra-delicate eraser for the removal of surface dirt. 5 €

Nanorestore Gel®
Peggy 5 Pen
Opalescent hydrogel based on poly (vinyl alcohol) polymeric network. The gel has a pen shape of about 8 cm length and 1.5 cm diameter. It allows for a controlled and localized humidification with a light mechanical action and can be used as a sort of ultra-delicate eraser for the removal of surface dirt. 10 €

Technical Information

When are they used?

The Nanorestore Gel® Peggy are useful when a controlled release of cleaning/detergent systems on a surface is necessary. Limiting the action of the cleaning systems used (water, solvents, micellar solutions, microemulsions, etc.) to the interphase gel/surface allows a more selective and controlled action during the removal of grime, dust and/or aged varnishes, reducing the risk of damaging the original materials and/or the underlying pictorial layer. Unlike the most common thickeners, used to increase the viscosity of liquids, gels can be considered as "containers", which allow to put the cleaning fluid in contact with the surface to be treated. Moreover, the gel can be removed from the surface by using tweezers or by delicately peeling the gel, without the need to perform a potentially harmful mechanical action on the substrate.

How do they work?

They are used as vehicle (containers) for the liquid cleaning agent. They prevent the cleaning agent from fast evaporation and uncontrolled penetration into porous materials making the cleaning safer. Moreover, thanks to their formulation they do not leave residues on the treated surface.

How are they used?

The gels are used as loaded with water, aqueous solutions, polar solvents or water-based nanostructured fluids of the Nanorestore Cleaning® series. When Nanorestore Gel® Peggy are removed from their container (or their original package), they can be cut down and shaped in the desired size and form. Then, prior to application, water excess on the gel surface has to be removed by placing the gel between two sheets of absorbent material (e.g., absorbing paper) and exert a light pressure with hands. After this operation, the gel surface will be dry and the gel can be applied on the surface to be treated. Just lay the gel on the surface that has to be cleaned, apply a little pressure with a finger or a suitable laboratory tool in order to optimize the adhesion of the gel and remove any air bubbles between the gel and the surface.
