Product reliability & consistency

Monomers which are used in Graphic Arts applications are low molecular weight substances which possess a potentially higher tendency for migration. It is essential therefore to ensure that the quality of the selected monomers is consistent from batch to batch, with any reaction by-products being assessed and quantified.

 

In order to meet the above requirements, Sartomer has developed a range of superior quality monomers under "Y*" references.

The development of this range is based on three fundamental pillars:

  • Thorough selection of raw materials
  • Strict process control
  • Analytical quality control process linked to tight specifications

 

*In all cases, it is essential that the end-user establishes the suitability of the selected monomers in each formulated ink/varnish systems intended for indirect food contact application.
