Bisphenol vs phenol
WebPHENOLITE is a novolac phenol resin for epoxy resin curing agents. When a novolac phenol resin is used, the cross-linking density of the cured material is higher and heat resistance, moisture resistance, and chemical resistance are superior when compared to other epoxy resin curing agents. Bisphenol F (BPF; 4,4′-dihydroxydiphenylmethane) is an organic compound with the chemical formula (HOC 6H 4) 2CH 2. It is structurally related to bisphenol A (BPA), a popular precursor for forming plastics, as both belong to the category of molecules known as bisphenols, which feature two phenol groups connected via a linking group. In BPF, the two aromatic rings are linked by a methylene conn…
