Isobornyl Methacrylate from Canada
Isobornyl methacrylate, derived from methacrylic acid and isoborneol, provides hardness in UV-curable coatings and dental composites. Classified as 'other' under HTS 2916.14.20, it meets Chapter 29 criteria for cyclic alcohol esters of acyclic acids by later numerical order rule. Its high Tg enhances cured film properties.

Import Tips
• Chiral purity documentation if enantiomerically pure; racemic mixtures still classify identically
• Viscosity specs (8-15 cps) verify against adulteration with lower monomers
• Light-tight packaging required; UV exposure initiates polymerization
