Description

Glyceryl Trimethacrylate is a trifunctional methacrylate monomer characterized by its high reactivity and ability to form cross-linked polymer networks. This compound is essential for creating durable, high-performance materials with enhanced thermal stability, chemical resistance, and mechanical strength. It is a critical raw material for manufacturers in the coatings, adhesives, dental composites, and optical lens industries seeking to improve product performance and longevity.

Application

Glyceryl Trimethacrylate is a versatile cross-linking agent used across multiple advanced manufacturing sectors.

• Coatings & Inks: As a key component in UV-curable coatings, printing inks, and overprint varnishes to provide scratch resistance, gloss, and durability.
• Dental & Medical Materials: Used in dental restorative composites, sealants, and bone cements to enhance strength, wear resistance, and biocompatibility.
• Adhesives & Sealants: Employed in anaerobic and structural adhesives to improve bonding strength, thermal stability, and environmental resistance.
• Optical Polymers: A monomer in the production of high-refractive-index optical lenses and transparent plastics.
• Composite Materials: Acts as a cross-linker in fiber-reinforced plastics (FRP) and gel coats to improve matrix properties.
• Modifier for Synthetic Resins: Used to modify the properties of acrylic, polyester, and other resins, impacting flexibility and hardness.

Quality Control

Our Glyceryl Trimethacrylate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets exacting specifications for industrial and specialized applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and organic solvents. For long-term storage, maintaining an inert gas (nitrogen) blanket is recommended to preserve monomer integrity.
