This parameter is used to estimate the mass of co-reactant (hardener) to work with when curing epoxy resins. Epoxies are generally cured with stoichiometric or near-stoichiometric quantities of hardener to obtain the most beneficial Bodily Houses. Looks-wise, epoxy morphs from a paste, liquid, or gel right into a hardened solid. https://www.propanraya.com/id/produk/epoxy-fast-dry
