The formulation may then be reacted in a similar way as pure bisphenol A. Some (non-crosslinked) epoxy resins with very superior molar mass are additional to engineering thermoplastics, again to attain flame retardant properties. The reaction between bisphenol A and epichlorohydrin results in a pre-polymer which is then reacted by https://www.propanraya.com/id/produk/epoxy-fast-dry
