Description

Lignosulfonic Acid, Sodium Salt, Polymer With Formaldehyde And Phenol CAS NO 37207-89-9 is a chemically modified, water-soluble polymer derived from lignin, a major component of wood pulp. This engineered compound matters for its exceptional performance as a versatile dispersant, binder, and complexing agent in demanding industrial processes. Key industries that need it include construction, agriculture, ceramics, and oilfield services, where it enhances product stability and process efficiency.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer to improve workability and strength of concrete mixes.
• Agricultural Formulations: Serves as a dispersant and binder in pesticide wettable powders, granules, and suspension concentrates for improved stability and application.
• Ceramic & Refractory Production: Functions as a binder and deflocculant in clay bodies and casting slips, enhancing green strength and moldability.
• Oilfield Drilling Fluids: Used as a thinner and dispersant in water-based muds to control rheology and fluid loss.
• Dye & Pigment Dispersions: Provides stabilization and prevents agglomeration in the production of concentrated colorants.
• Industrial Cleaners: Acts as a sequestrant and dispersant for scale and particulate matter in boiler and cooling water treatment.
• Foundry Sand Binders: Used as a core binder in metal casting processes for its binding properties and thermal stability.
• Pelletizing & Briquetting: Employed as a natural binder in the agglomeration of fine powders like minerals, coal dust, and animal feed.

Quality Control

Our Lignosulfonic Acid, Sodium Salt, Polymer With Formaldehyde And Phenol undergoes rigorous quality testing to ensure batch-to-batch consistency and performance for your specific application. We adhere to stringent internal specifications that monitor key parameters such as active content, sulfonation degree, and molecular weight distribution. Certificates of Analysis (COA) documenting purity, physical properties, and performance tests 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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
