High water solubility with rapid dissolution in cold to warm water.
Excellent film-forming capability and strong adhesion to polar substrates.
Good compatibility with starch, cellulose derivatives, and various water-based resins.
Low residual acetaldehyde content, supporting stringent regulatory requirements for food-contact and pharmaceutical applications.
Consistent batch-to-batch reproducibility due to Kuraray’s controlled polymerization and hydrolysis process.
Water-soluble packaging films (e.g., detergent pods, agrochemical sachets).
Binder in ceramic and refractory green bodies for improved green strength and clean burnout.
Thickener and stabilizer in aqueous pigment dispersions for inkjet inks and textile printing pastes.
Protective colloid in emulsion polymerization of vinyl acetate and acrylic monomers.
