Description

Dextrin, Polymer With Formaldehyde CAS NO 53740-05-9 is a chemically modified polysaccharide derivative, formed by the cross-linking reaction of dextrin with formaldehyde. This product is valued for its ability to act as a versatile binder, adhesive, and film-forming agent, offering improved water resistance and mechanical properties compared to native dextrin. It is primarily utilized in industries such as foundry core binding, paper and textile sizing, and as a component in construction materials and specialty adhesives.

Application

• Foundry Binder: Used as a core and mold binder in metal casting for its good collapsibility and strength.
• Paper & Textile Sizing: Acts as a surface sizing agent to improve strength, stiffness, and printability of paper and textiles.
• Adhesive Formulation: Serves as a base for remoistenable adhesives, corrugated board, and label pastes.
• Construction Materials: Functions as an additive in gypsum boards, plasters, and other building materials to enhance workability and adhesion.
• Pelletizing & Agglomeration: Employed as a binder in the agglomeration of powders for fertilizers, ceramics, and catalysts.
• Pharmaceutical Excipient: Can be used as a tablet binder and disintegrant in specific pharmaceutical formulations (subject to appropriate grade and compliance).

Quality Control

Our Dextrin, Polymer With Formaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistency and performance for its intended industrial applications. While specific grades are available, we ensure compliance with relevant industrial specifications. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking or degradation due to moisture absorption.
