An absorbent binder desiccant composition is provided which is capable of spontaneous crosslinking after application to a substrate, at a temperature of about 120° C. or less. The absorbent binder desiccant composition includes a monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, or a quaternary ammonium salt, and an acrylate or methacrylate ester that contains an alkoxysilane functionality, or a monomer capable of co-polymerization with a compound containing a trialkoxy silane functional group and subsequent reaction with water to form a silanol group, and a desiccant component. The absorbent binder desiccant composition is particularly suitable for use in manufacturing a wide variety of humidity control articles.
An absorbent binder desiccant composition comprising a water-soluble ionic polymer capable of sufficient non-radiative crosslinking within about 10 minutes at a temperature of about 120° C. or less, to reach an absorbent capacity of at least one gram of fluid per gram of polymer using the centrifuge retention capacity test, and at least one desiccant component.
An absorbent binder desiccant composition comprising an absorbent binder component and a desiccant component in a dry weight ratio of about 100:1 to about 1:10, wherein the absorbent binder component comprises:
A combination of an absorbent binder desiccant structure and a substrate, wherein the absorbent binder desiccant structure is formed from an absorbent binder component comprising a water-soluble polymer capable of sufficient non-radiative crosslinking within about 10 minutes at a temperature of about 120° C. or less, to reach an absorbent capacity of at least one gram of fluid per gram of polymer using the centrifuge retention capacity test, and a desiccant component.
