Nanorestore Gel®

Overview

Nanorestore Gels® are water-based chemical gels, which leave no residues on the surface of the treated artifacts. Thanks to their highly retentive network they can be used also on water-sensitive surfaces because their action is limited to the interface, thus only a small amount of liquid is released to the surface. Nanorestore Gels® are sold loaded with water, but they can be also loaded with polar solvents (such as ethanol) or water-based nanostructured fluids of the Nanorestore Cleaning® series.

Available Formulations
Nanorestore Gel®
Dry
Transparent chemical hydrogel based on a pHEMA/PVP semi-interpenetrated network having high retention of loaded liquid. Can be safely used on water-sensitive substrates. Each package contains a water-loaded sheet (approx. 150 cm2 - 2 mm thick), which can be reused up to 4-5 times, depending on the specific case. 15 €
Nanorestore Gel®
Extra Dry
Transparent chemical hydrogel based on a pHEMA/PVP semi-interpenetrated network having very high retention of loaded liquid. Can be safely used on particularly water-sensitive substrates. Each package contains a water-loaded sheet (aapprox. 150 cm2 - 2 mm thick), which can be reused up to 4-5 times, depending on the specific case. 15 €
Nanorestore Gel®
Max Dry
Transparent chemical hydrogel based on a pHEMA/PVP semi-interpenetrated network having the maximum retention of loaded liquid. Can be safely used on substrates that cannot tolerate water. Each package contains a water-loaded sheet (approx. 150 cm2 - 2 mm thick), which can be reused up to 4-5 times, depending on the specific case. 15 €
Nanorestore Gel®
Test Kit
This kit includes one water-loaded sheet (approx. 70 cm2 - 2 mm thick) of each of the Nanorestore Gel® series formulations. It could be used for preliminary tests, in order to choose the best formulation for your specific need. 20 €

Technical Information

When are they used?

Cleaning of water-sensitive (painted) surfaces is a very delicate operation, since detergent systems have to perform a selective and controlled action to remove grime, dirt and/or aged varnishes without affecting the original materials and/or the underlying pictorial layer. Gels are usually used for this purpose. Traditional gelled systems offer quite good performances, but their nature makes them very hard to be removed from the cleaned surface and might produce irreversible damages to the pictorial layer. Nanorestore Gels® are designed to overcome the limits of traditional gels.

How do they work?

They are used as vehicle (containers) for the liquid cleaning agent. They prevent the liquid 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 surfaces.

How are they used?

The transparent gels are used as loaded with water, aqueous solutions, several solvents or water-based nanostructured fluids of the Nanorestore Cleaning® series. The loaded gel is applied over the surface, and the undesired layers (dirt, grime, aged varnishes, adhesives etc.) are either dissolved (and migrate into the gel) or swollen/softened and removed by gentle mechanical action directly after the removal of the gel form the surface.
