Description

Urethane Dimethacrylate Luting Resin CAS NO 125523-74-2 is a high-performance, cross-linking monomer specifically engineered for demanding dental and industrial adhesive formulations. This compound matters because it provides exceptional bond strength, durability, and low polymerization shrinkage, which are critical for long-lasting applications. It is primarily needed by manufacturers of dental cements, composite materials, and high-strength industrial adhesives seeking reliable performance and enhanced mechanical properties.

Application

• Dental Luting Cements: A key component in permanent and temporary dental cement formulations for crowns, bridges, and inlays.
• Dental Composite Resins: Used as a co-monomer to enhance the fracture toughness and wear resistance of restorative composites.
• Industrial Adhesives: Formulated into high-strength structural adhesives for bonding metals, ceramics, and engineered plastics.
• 3D Printing Resins: Serves as a reactive diluent and cross-linker in stereolithography (SLA) and digital light processing (DLP) resins for high-resolution prints.
• Coating & Sealant Formulations: Imparts chemical resistance and durability to protective coatings and specialty sealants.
• Optical Lens Manufacturing: Utilized in the production of scratch-resistant optical lenses and related polymer articles.

Quality Control

Our Urethane Dimethacrylate Luting Resin undergoes rigorous quality testing to ensure compliance with industry standards for purity and performance. Production is aligned with GMP (Good Manufacturing Practice) guidelines where applicable. Comprehensive Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed to prevent moisture absorption and degradation.
