Nanorestore® Paper Propanol 5 g/l: Calcium hydroxide nanoparticles dispersed in 2-propanol at a concentration of 5 g/l.
Nanorestore® Paper formulations are specifically designed for the pH control and deacidification of cellulose-based artifacts. Calcium hydroxide nanoparticles are used to raise the artifact's pH around neutrality (7.0 - 8.0). Neutrality prevents the degradation of cellulose due to acid-catalyzed hydrolysis and also hampers metal-catalyzed oxidation.
OK to be used for
- Deacidification and pH control of the blank paper.
- Deacidification and pH control of printed books.
- Deacidification and pH control of iron and metal gall ink manuscripts.
- Deacidification and pH control of wooden artifacts.
- Deacidification and pH control of canvas, i. e., the backside of easel paintings.
How do they work?
Calcium hydroxide nanoparticles of Nanorestore® Paper formulations adhere to the cellulose fibers and rapidly neutralize acidity on site. The excess of particles reacts with CO2 in the atmosphere, turning into carbonate, granting protection against reoccurring acidity.
