Description

Dimethyl Tin Dilaurate is an organotin compound widely recognized as a highly effective catalyst and stabilizer. Its primary commercial value lies in accelerating polyurethane (PU) foam formation and acting as a potent heat stabilizer for PVC and other polymers. This product is essential for manufacturers in the polymer and plastics industries seeking to optimize production efficiency and enhance material performance. The compound is supplied under strict quality control to ensure batch-to-batch consistency for industrial applications.

Application

• Polyurethane Foam Catalyst: A key catalyst for promoting the reaction between polyols and isocyanates in flexible, rigid, and microcellular PU foam production.
• PVC Heat Stabilizer: Provides excellent long-term thermal stability for polyvinyl chloride (PVC) compounds used in pipes, profiles, and cables.
• Polymerization Catalyst: Used as a catalyst in esterification and transesterification reactions for producing polyesters and other polymers.
• Silicone Cross-linking Agent: Acts as a catalyst in the curing of silicone rubbers and resins.
• Lubricant Additive: Serves as an anti-wear and extreme pressure additive in industrial lubricants and greases.
• Adhesive & Sealant Formulation: Employed to control cure rates and improve the thermal properties of various adhesive and sealant systems.

Quality Control

Our Dimethyl Tin Dilaurate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for tin content, acidity, and color. A Certificate of Analysis (COA) detailing purity, assay, and key physical-chemical parameters is provided with each shipment to guarantee traceability and compliance with your formulation requirements.

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 contact with atmospheric moisture. Keep away from strong alkalis and incompatible materials.
