The formulation may then be reacted in the identical way as pure bisphenol A. Some (non-crosslinked) epoxy resins with quite large molar mass are added to engineering thermoplastics, once more to realize flame retardant properties. The reaction concerning bisphenol A and epichlorohydrin results in a pre-polymer that's then reacted which https://www.propanraya.com/id/produk/epoxy-fast-dry
