Esschem Europe's  high-purity monomers are ideal for optical and medical applications, providing manufacturers with consistent low colour, appropriate inhibitor packages, consistent low acid and enhanced stability. These requirements must continually be met without deviation in order to efficiently manufacture quality materials.

High Purity Monomers:

HEMA is a primary alcohol making it a good adhesion promoter in anaerobic adhesives. The purity level of this methacrylate monomer also makes it cost efficient.
