Ethylene Glycol Dimethacrylate (EGDMA) from Germany
Ethylene glycol dimethacrylate (EGDMA) is a difunctional crosslinking monomer for improved mechanical properties in resins. Though di-functional, it classifies as 'other' methacrylic ester under HTS 2916.14.20 since Chapter 29 prioritizes monocarboxylic acid ester heading. Used in dental composites and 3D printing resins.

Import Tips
• Functionality testing (double bond equivalence) confirms difunctional nature
• Refractive index (1.45-1.46) purity check
• Avoid copper/iron contamination; accelerates polymerization
