Description

Vinol 540 is a high-purity, water-soluble polymer belonging to the polyvinyl alcohol (PVA) family, identified by CAS No. 98002-50-7. This versatile chemical is engineered to provide exceptional binding, film-forming, and emulsifying properties, making it a critical component in demanding industrial formulations. It is essential for manufacturers in sectors such as adhesives, paper processing, textiles, and construction chemicals who require consistent performance and reliable supply chain partners.

Application

• Adhesive Formulations: Serves as a primary binder and thickener in water-based adhesives for paper, wood, and packaging.
• Paper & Paperboard Coating: Used as a strength agent and coating binder to improve surface properties, printability, and grease resistance.
• Textile Sizing: Acts as a warp sizing agent to protect yarns during weaving, offering excellent film strength and easy removal.
• Construction Chemicals: Functions as a non-redispersible powder in tile adhesives, mortars, and self-leveling compounds to enhance workability and adhesion.
• Polymerization Aid: Employed as a protective colloid and stabilizer in the emulsion polymerization of vinyl acetate and other monomers.
• Ceramic & Mold Binder: Provides green strength in ceramic bodies and precision casting molds.

Quality Control

Our Vinol 540 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including degree of hydrolysis, viscosity, and purity. A Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are kept sealed to prevent moisture absorption and caking.
