description Product Description
Used in textile sizing and finishing to improve strength and smoothness of yarns and fabrics. Commonly employed as a water-soluble film in packaging, especially for detergents and agrochemicals, due to its biodegradability. Applied in paper coatings to enhance printability and moisture resistance. Widely used in adhesives for paper and wood products because of its strong bonding and water-based formulation. Utilized in the pharmaceutical industry for encapsulation and as a coating agent in tablets. Found in eye drops and contact lens solutions as a lubricant. Used in construction materials as a binder and film-forming agent in cement and plaster formulations. Also serves as a thickener and stabilizer in aqueous formulations across cosmetics and coatings. Additionally, employed in ceramics and powder metallurgy as a binder to facilitate product forming prior to firing.
