Description

Cresol/Phenol,Sulfonated/ Urea-Formaldehyde/ Sulfonic Acid CAS NO 103332-05-4 is a specialized synthetic resin intermediate, a sulfonated co-condensate of cresol, phenol, urea, and formaldehyde. This compound is engineered to provide enhanced solubility, reactivity, and ionic character for demanding industrial formulations. It is primarily utilized by manufacturers in the production of advanced ion-exchange resins, specialty adhesives, and high-performance concrete plasticizers.

Application

• Ion-Exchange Resin Precursor: A key intermediate in the synthesis of cation-exchange and mixed-bed resins for water purification, chemical processing, and hydrometallurgy.
• Concrete Admixtures: Acts as a raw material for producing high-range water-reducing superplasticizers, improving workability and strength in concrete formulations.
• Specialty Adhesives & Binders: Used in formulating phenolic and urea-formaldehyde based adhesives with modified solubility and curing properties for wood composites and abrasives.
• Dye & Pigment Intermediate: Serves as a sulfonating agent and dispersant aid in the synthesis and stabilization of organic dyes and pigments.
• Oilfield Chemicals: Employed in the formulation of drilling mud additives and scale inhibitors due to its dispersant and chelating characteristics.
• Textile & Leather Auxiliaries: Functions as a tanning agent and dye-fixing assistant in leather processing and textile dyeing operations.

Quality Control

Our production of Cresol/Phenol,Sulfonated/ Urea-Formaldehyde/ Sulfonic Acid adheres to stringent quality management protocols. Each batch is characterized for critical parameters including sulfonation degree, molecular weight distribution, and functional group content to ensure batch-to-batch consistency for your processes. Certificates of Analysis (COA) documenting purity, viscosity, solids content, and acidity are available upon request.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can alter physical properties. Keep away from strong bases and oxidizing agents.
