Background

These substances were previously evaluated under the Second Phase of Polymer Rapid Screening. That assessment found that the 4 epoxy resins were identified as requiring further assessment due to potential human health and/or ecological risks. Therefore, conclusions were not reached for these 4 substances in that assessment.
