Monomers and Oligomers

Acrylates, Epoxy Acrylates and Polyester Acrylates

The following table shows the Monomers and Oligomers I have been testing. These are samples I have sourced from Sartomer and they are some of the best candidates for our UV/Visible cure resin systems. I have listed the properties the compounds should impart, leaving blanks where the information is not given/known.

Several final resin systems will result from mixing several of these monomers and oligomers as none has the best combinations of properties by it's own. There will be several resin systems as we may want to push for certain properties that are very specific for some applications or are opposing properties.
