Chemically modified HPMC, through processes such as esterification, etherification, or crosslinking, enhances its adhesive properties significantly. These modifications introduce new functional groups that not only improve adhesion strength but also offer better control over the bonding characteristics. For instance, esterification introduces hydrophobic moieties, enabling enhanced adhesion to hydrophobic surfaces, while crosslinking results in increased mechanical stability and durability.
