Description

Dehydran 490 is a high-performance chemical additive widely utilized in industrial formulations. Its primary value lies in its exceptional efficacy as a defoamer and air-release agent, which is critical for ensuring the quality and performance of final products in demanding manufacturing processes. This product is essential for industries where foam control and material integrity are paramount, such as in coatings, adhesives, construction chemicals, and industrial cleaning systems. Dehydran 490 CAS NO 72779-49-8 offers reliable performance to enhance process efficiency and product stability.

Application

• As a highly effective defoamer and air-release agent in water-based and solvent-based industrial coatings and paints.
• For controlling foam in the production of adhesives and sealants, improving application properties and final appearance.
• In construction chemical formulations such as cement additives, grouts, and self-leveling compounds to prevent air entrapment.
• As a process aid in industrial and institutional (I&I) cleaning products to suppress foam during use.
• For foam mitigation in paper and pulp processing chemicals and coating formulations.
• In the manufacture of printing inks to ensure smooth application and prevent defects.
• As an additive in textile auxiliaries and dyeing processes to control foam generation.
• For enhancing the performance of metalworking fluids and coolants by eliminating problematic foam.

Quality Control

Our Dehydran 490 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. While it is an industrial-grade additive, production adheres to relevant industry standards for raw material and process control. Comprehensive testing is performed to verify key parameters such as defoaming efficiency, compatibility, and stability. Certificates of Analysis (COA) documenting these specifications are available upon request 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 / 59-77°F). Keep away from heat sources and open flame. Ensure the container is kept tightly sealed when not in use to prevent contamination and maintain product efficacy.
