Description

Vinyl Acetal Polymers, Glyoxals are a class of specialized polymers formed from the reaction of polyvinyl alcohol with glyoxal. These materials are valued for their unique cross-linking capabilities, water solubility, and film-forming properties, making them essential functional additives in demanding industrial formulations. They are primarily utilized by manufacturers in the coatings, adhesives, textile, and paper industries seeking to enhance product performance, durability, and processing characteristics.

Application

• Cross-linking Agent for Coatings: Imparts improved hardness, chemical resistance, and water resistance in water-based industrial and architectural paints.
• Paper Sizing and Wet-Strength Resin: Enhances the dry and wet strength of paper and paperboard, improving printability and durability.
• Textile Finishing Agent: Used for durable press (DP) and wrinkle-resistant finishes on cotton and cellulose-based fabrics.
• Adhesive Formulation: Acts as a binder and cross-linker in adhesives, particularly for porous substrates like wood and paper.
• Release Coatings and Films: Employed in the production of water-soluble films for packaging and release layers.
• Pharmaceutical Excipient: Serves as a film-coating agent or binder in tablet formulations for controlled release.

Quality Control

Our Vinyl Acetal Polymers, Glyoxals are manufactured under a strict quality management system. Each batch is tested to ensure consistent performance in key parameters such as degree of acetalization, viscosity, solids content, and solution clarity. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep container tightly sealed when not in use to prevent moisture absorption and potential viscosity changes.
