The industry has long known that the casein protein polymer is effective as a functional ingredient for technical applications because of the multiplicity of reaction modes that it can perform. Until recently, however, the preparation of casein protein polymer solutions proved difficult, leaving many potential users unable or unwilling to invest in this unique and versatile polymer. Caseinates eliminate this difficulty by creating water-soluble casein salts with differing metal ions attached to the molecule. This promotes ease of make-down, order of addition flexibility and reduced usage of alkalies as well as minimal cleanup. Ammonium, sodium, calcium and potassium are among the more popular ions being used in technical applications.

The caseinate protein polymer can react as a hydroxyl source, an amino
source, and a carboxyl source in a variety of interpenetrating polymer networks. Its amphoteric nature makes it a preferred co-binder in multiple polymer systems.

The caseinate protein polymer has come of age in the technical industry for any water-based application, as well as some solvent-based applications. Industries seeking materials with zero VOC's which possess this high degree of crosslinking, density-promoting activity will find the caseinate protein polymer an excellent addition to their polymer choices.
