Description

Calcium Diacrylate is a versatile organometallic compound widely utilized as a crosslinking agent and reactive monomer. Its primary value lies in its ability to form durable polymer networks, enhancing the mechanical and chemical resistance properties of various materials. This product is essential for manufacturers in the polymer, adhesive, and specialty chemical industries seeking to improve product performance and stability.

Application

• Crosslinking Agent for Polymers: Used to create three-dimensional networks in acrylic and vinyl polymers, improving their heat resistance and dimensional stability.
• Dental & Medical Materials: A key component in the formulation of light-curable dental composites, restorative materials, and bone cements.
• Adhesives & Sealants: Imparts enhanced adhesion, cohesion, and water resistance to industrial and construction-grade adhesives.
• Coatings & Inks: Serves as a reactive diluent and crosslinker in UV-curable coatings, inks, and varnishes for rapid curing.
• Superabsorbent Polymers (SAP): Employed in the synthesis of SAPs used in hygiene products (e.g., diapers) and agricultural water-retention gels.
• Grouting & Cement Modifiers: Enhances the flexibility, waterproofing, and durability of cementitious grouts and construction materials.

Quality Control

Our Calcium Diacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing the results for all critical parameters are provided to guarantee supply reliability and batch-to-batch consistency for your formulations.

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) and must be kept in a dry environment to prevent caking and degradation. Keep away from incompatible materials such as strong oxidizing agents.
