Welcome to Fix-It Friday -- a monthly series that proposes to bring you a bit of news you can use to help repair and conserve books! This month, some information on a very useful bookbinding adhesive that can make book repair a kinder, gentler process for books and for you: methyl cellulose.
Methyl cellulose is a chemical compound derived from cellulose. When mixed with water, it can be used as a low-tack adhesive that is often added to PVA in bookbinding. The addition of methyl cellulose to PVA slows the drying time of PVA without compromising its strength.
Application of straight methyl cellulose to previously glued materials can also help break down and loosen old adhesive. It is used to clean old paper linings, adhesive, and super cloth from spines when preparing books for hollow tubes and rebacking.
