See our Privacy Policy and User Agreement for details. Liquid resins and curatives can form low-viscosity, easily modified systems. Pure epoxy resins are usually mixed as two ingredients (a resin and a hardener, often an amine) of equal or integrally proportionate (stoichiometric) ratios to produce a material that cures slowly with little shrinkage. The limiting oxygen index value of cured epoxy resin increased from 21.1% to 30.0% with increasing phosphorus compound/phosphorus content from 0/0 to 36.8/2.5 wt%. In this study, epoxy, the most common type of polymer used by civil engineers is used to produce polymer resin. Epoxy resins. Learn more.
