Cycloaliphatic epoxy resin refers to a series of products obtained by oxidation with butadiene and acrolein as base materials and the mixture of hydrogen peroxide and peracetic acid as oxidant. Epichlorohydrin is not selected as the synthetic base material, thus, the molecular structure does not contain any benzene ring and hydroxyl group, and the epoxy group is directly connected to the cycloaliphatic ring through oxidation-reduction.
