valPure® NBPA Epoxy Studies and Research
The new valPure V70 Series of non-BPA* epoxy technologies represents the future of epoxy coatings for light metal packaging.
valPure V70 offers the universality of epoxy coatings, food safety and preservation, while answering the need for choices in the market and delivering on consumer preference.
Studies/Research
The initial screen of the Safety by Design process included a review of the literature, computational modeling, Quantitative structure–activity relationship (QSAR), and read-across for toxicity prediction. From this screen, a select few candidates were chosen, based upon their predicted safety profiles, for further in-vitro polymer synthesis studies. Only the safest chemicals were chosen from the initial screen to develop valPure NBPA Epoxy. Extensive testing, including 3rd-party laboratory testing, demonstrates evidence for an absence of genotoxicity and endocrine activity.
