Description

Strontium methacrylate is an organometallic monomer featuring a reactive methacrylate group bonded to a strontium cation. This compound is valued for its ability to introduce strontium ions into polymer matrices, imparting specific functional properties such as enhanced refractive index, X-ray opacity, or bioactivity. It is primarily utilized by manufacturers and R&D professionals in the advanced materials, specialty polymers, and biomedical sectors seeking to develop novel composite materials.

Application

• Dental and Biomedical Composites: As a key component in resin-based composites and cements to provide radiopacity for X-ray imaging and potential bioactive benefits for bone-contact applications.
• Optical Polymers and Coatings: To modify the refractive index of acrylic polymers for lenses, optical adhesives, and advanced coating systems.
• Cross-linking Agent for Specialty Elastomers: Used to introduce ionic cross-links into polymer networks, enhancing the mechanical and thermal properties of synthetic rubbers and adhesives.
• Flame Retardant Additives: Serves as a reactive intermediate in the synthesis of polymeric flame retardants, where strontium can contribute to smoke suppression.
• Catalyst and Reagent in Organic Synthesis: Employed as a precursor or catalyst in various organic transformations and polymerization reactions.
• Surface Modification and Grafting: Used to functionalize inorganic particle surfaces (e.g., glass, ceramics) with polymerizable groups for improved composite material interfaces.

Quality Control

Our strontium methacrylate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing purity, heavy metal content, and other critical parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation by moisture absorption. Keep away from heat, sparks, and open flame.
