Description

Lead(4+) Stearate is an organometallic salt of stearic acid and lead, known for its role as a high-temperature stabilizer and lubricant. This compound is valued in industrial formulations for its ability to impart thermal stability and reduce friction in polymer processing. It serves as a critical additive for manufacturers in the plastics, coatings, and specialty chemical sectors requiring reliable performance under demanding conditions.

Application

• Polymer Stabilizer: Acts as a heat stabilizer and lubricant in the processing of PVC and other halogenated polymers.
• Grease & Lubricant Additive: Used as a thickening agent and extreme pressure additive in high-temperature greases and industrial lubricants.
• Coatings & Paints: Functions as a drier and stabilizer in certain paint, varnish, and coating formulations to promote curing and prevent skinning.
• Plastic Processing Aid: Improves flow properties and reduces internal friction during the extrusion and molding of engineering plastics.
• Waterproofing Agent: Imparts water-repellent properties to textiles, paper, and construction materials.
• Corrosion Inhibitor: Used in protective coatings and primers for metal surfaces.
