Cellugel
Cellugel uses cellulose ethers
(specifically hydroxypropylcellulose) and isopropanol to treat red rot by penetrating the surface
of leather. It consolidates the leather substrate, depositing a thin film
which provides resistance to atmospheric conditions but does not darken or
discolor leather surfaces. It will not stain other materials it comes in
contact with. Cellugel dries quickly and the book
may soon be handled safely. A second coat may prove necessary for extremely
thick or badly deteriorated volumes. It is an excellent choice for
consolidating powdery leather surfaces prior to conservation treatments. If
the top is kept closed, the product should not evaporate, however, a little
100% isopropanol may be used for thinning. Water
should never be used, as it will cause staining and blackening of leather
surfaces. Expect a 16-oz jar to treat about 60 books measuring approximately
6 x 9 in.
No special ventilation is required.
