Description

Lignosulfonic Acid, Calcium Salt, Polymer With Cyanoguanidine, Formaldehyde And Sodium Lignosulfonate CAS NO 95649-13-1 is a specialized, high-performance synthetic polymer derived from modified lignin. This engineered compound is valued for its multifunctional properties, including excellent dispersing, binding, and complexing capabilities. It is primarily utilized in demanding industrial applications where robust performance and material stability are critical, such as in construction materials, agricultural formulations, and specialty chemical manufacturing.

Application

• Concrete Admixtures & Water Reducers: Acts as a highly effective plasticizer and dispersant in cement and concrete formulations to improve workability and reduce water content.
• Agricultural Dispersants & Binders: Used in the formulation of wettable powders, suspension concentrates (SC), and granules for pesticides and fertilizers to enhance stability and dispersion.
• Oil Well Drilling Fluids: Serves as a fluid loss control additive and thinner in drilling muds to maintain viscosity and stability under high-temperature, high-pressure conditions.
• Ceramic & Refractory Industry: Functions as a binder and deflocculant in ceramic slips and refractory castables to improve green strength and casting performance.
• Dye & Pigment Dispersants: Provides effective dispersion and stabilization for dyes and pigments in textile, paint, and ink manufacturing.
• Industrial Detergents & Cleaners: Incorporated into formulations for its sequestering and soil-suspending properties, particularly in hard surface cleaners.
• Pellet Binders: Used as an organic binder in the agglomeration process for iron ore pellets, coal briquettes, and animal feed.
• Leather Tanning Auxiliaries: Acts as a dispersing and filling agent in leather processing to improve the quality and uniformity of the final product.

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. Keep away from incompatible materials.
