who makes styrenated phenolic resins equivalent to si group

    Epoxy - Wikipedia

    An important criterion for epoxy resins is the epoxide group content. This is expressed as the "epoxide equivalent weight", which is the ratio between the molecular weight of the monomer and the number of epoxide groups. This parameter is used to calculate the mass of co-reactant (hardener) to use when curing epoxy resins.
