Description

Strontium 2-Ethylhexanoate is a metal-organic compound, specifically a strontium salt of 2-ethylhexanoic acid. This versatile metal carboxylate is valued for its role as a highly effective catalyst and stabilizer in polymer synthesis and as a key component in specialty coatings and additives. It is primarily sought by manufacturers in the plastics, paint, and advanced materials industries for applications requiring precise metal ion incorporation and thermal stability.

Application

• Polymerization Catalyst: Acts as a co-catalyst or catalyst component in the production of polyesters, polyurethanes, and other specialty polymers.
• PVC Stabilizer: Functions as a heat stabilizer in polyvinyl chloride (PVC) formulations, particularly in combination with other metal soaps like zinc or calcium.
• Driers for Paints & Coatings: Used as a through-dry catalyst in alkyd resin-based paints, varnishes, and printing inks to promote uniform film formation and hardening.
• Ceramic & Glass Precursor: Serves as a strontium source in sol-gel processes and the production of specialty ceramics, glasses, and ferrite materials.
• Additive for Greases & Lubricants: Imparts thickening and stabilizing properties in high-temperature lubricating greases.
• Crosslinking Agent: Utilized in silicone rubber and other elastomer systems to facilitate crosslinking and improve thermal properties.

Quality Control

Our Strontium 2-Ethylhexanoate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity, metal content, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment to guarantee compliance with your technical 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 absorption of atmospheric moisture, which can affect product quality.
