Description

2,2,4-Trimethyl-1,3-Pentanediol Dimethacrylate is a high-purity, difunctional methacrylate monomer characterized by its rigid alicyclic core. This compound matters for its exceptional performance in creating cross-linked polymer networks with enhanced hardness, chemical resistance, and thermal stability. It is primarily needed by formulators in the coatings, adhesives, and advanced composites industries seeking to improve the durability and mechanical properties of their final products. CAS NO 13283-44-8.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for producing hard, scratch-resistant, and glossy finishes on plastics, metals, and wood.
• Dental & Biomedical Composites: Used in restorative materials and bone cements for its biocompatibility and ability to form rigid, durable polymer matrices.
• Adhesives & Sealants: Imparts high cohesive strength and resistance to environmental factors in structural and industrial adhesive formulations.
• Fiber-Reinforced Plastics (FRP): Serves as a reactive diluent and cross-linker in resin systems for automotive and marine composites.
• Optical Lenses & Components: Employed in casting resins for lenses due to its clarity, low shrinkage, and high refractive index upon polymerization.
• Lithographic Printing Plates: A critical monomer in photopolymerizable layers for creating high-resolution, durable printing plates.
• 3D Printing Resins (SLA/DLP): Enhances the toughness and heat deflection temperature of printed objects in stereolithography resins.

Quality Control

Our 2,2,4-Trimethyl-1,3-Pentanediol Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, inhibitor content, and color are available for every shipment 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 product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) to maintain stability and prevent premature polymerization. Keep away from heat, sparks, and open flame.
