Description
These resins, some with a history of safe use in human health applications exceeding 50 years, continue to be far safer than many alternative technologies offered which are not based on epoxy and do not suffer from the same saponification problems associated with polyesters. Jana is also able to supply suitable resins for the production of epoxy esters and epoxy polysiloxanes.
