Esschem Europe offer a  range of adhesive monomers from the Esstech affiliate. Several systems are available for bonding to dentine or metals. These adhesives are used in restorative and composite dental materials, but also find use in cosmetic nail systems and other applications

Adhesive Monomers:

Advancing upon our existing Pyromellitic glycerol dimethacrylate product, Esschem Europe now offer PMDGM, also known as Bis ( Glyceryl Dimethacrylate) Pyromellitate, in acetone solution with increased stability. PMDGM can make an ideal adhesive system for using its four methacrylate groups and two carboxylic acid groups to bond to various substrates.
