Description

1,12-Dodecanediol Dimethacrylate is a high-purity, long-chain difunctional methacrylate monomer, essential for creating cross-linked polymer networks with enhanced flexibility and chemical resistance. Its primary value lies in its ability to act as a reactive diluent and cross-linking agent, imparting durability and specific performance characteristics to final materials. This product is critical for manufacturers in the photopolymer, specialty coatings, advanced adhesives, and dental composite industries seeking to develop high-performance, tailored polymeric systems.

Application

• Photopolymer Resins & 3D Printing: A key component in stereolithography (SLA) and digital light processing (DLP) resins, contributing to low shrinkage and improved toughness in printed parts.
• Specialty Coatings & Inks: Used in UV-curable coatings, inks, and overprint varnishes to enhance flexibility, adhesion, and chemical resistance on various substrates.
• Dental Composites & Restoratives: Serves as a cross-linking monomer in dental filling materials and restorative composites, improving mechanical strength and wear resistance.
• Advanced Adhesives & Sealants: Incorporated into anaerobic, acrylic, and UV-curing adhesives to modify viscosity and final polymer properties like impact resistance.
• Fiber Optic Coatings: Used in the primary and secondary coatings for optical fibers, providing essential protective and mechanical properties.
• Optical Lenses & Components: Employed in the production of plastic lenses and optical elements where precise cross-linking and clarity are required.

Quality Control

Our 1,12-Dodecanediol Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and assay, GC for residual monomer and solvent content, and IR for identification, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Incompatible with strong acids and oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
