Description

Benzenesulfonic acid, 4-hydroxy-, polymer with formaldehyde and urea, reaction products with aniline, 1,3-bis(hydroxymethyl)urea, 4,5-dihydroxy-1,3-bis(hydroxymethyl)-2-imidazolidinone, disodium disulfite, formaldehyde, tetrahydro-3,5-bis(hydroxymethyl)- is a specialized synthetic polymer with a complex, cross-linked structure designed for high-performance applications. This engineered material is valued for its ability to provide enhanced stability and functional properties in demanding industrial formulations. It is primarily sought by manufacturers in sectors requiring advanced polymeric additives, such as resin modification, specialty coatings, and functional material synthesis.

Application

• Cross-linking agent and modifier for thermosetting resins (e.g., phenolic, urea-formaldehyde resins) to improve mechanical strength and thermal stability.
• Functional additive in industrial coatings and adhesives to enhance durability, chemical resistance, and adhesion properties.
• Component in advanced composite materials for the automotive and aerospace industries, where tailored polymer properties are critical.
• Intermediate for synthesizing specialty polymers with specific ionic or reactive functionalities for niche chemical applications.
• Additive in textile auxiliaries to impart wrinkle resistance, flame retardancy, or other finish properties to fabrics.
• Potential use in ion-exchange materials or chelating agents due to its complex structure containing sulfonic and hydroxyl groups.

Quality Control

Our production of this advanced polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical methods including FT-IR for structural identification, viscosity measurement, and thermal analysis (TGA/DSC). A comprehensive Certificate of Analysis (COA) detailing specific lot parameters is provided with every shipment to support your quality assurance and regulatory needs.

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 easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain its functional integrity. Keep away from strong oxidizing agents and incompatible materials.
