Description

Phenol, Polymer With Formaldehyde, Sulfomethylated, Sodium Salt is a water-soluble, anionic phenolic resin derivative. This modified polymer is engineered to offer enhanced dispersing, binding, and complexing properties in demanding industrial formulations. It serves as a critical functional additive in sectors requiring high-performance water treatment and material synthesis, where its sulfomethylated structure provides superior solubility and reactivity.

Application

• Dispersant in Water Treatment: Acts as a scale and corrosion inhibitor in cooling water and boiler water systems.
• Tannin-Based Dispersant: Used in leather tanning and processing to improve dye penetration and uniformity.
• Adhesive & Binder Component: Employed in the formulation of foundry resins, abrasives, and refractory materials.
• Oilfield Chemical: Functions as a fluid loss additive and thinner in drilling mud formulations.
• Textile Auxiliary: Serves as a dyeing assistant and dispersing agent for synthetic fibers.
• Ceramic & Cement Additive: Enhances the workability and reduces the water content in ceramic slips and cement mixtures.
