Development of polymer network of phenolic and epoxies resins mixed with linseed oil: pilot study [PDF]
, 2010 Epoxy resin was mixed with phenolic resins in different percentages by weight. Composite 40/60 means the proportion by weight of epoxy resin is 40 percent. It was found that only composites 50/50 and 40/60 could be cured in ambient conditions. Dynamic
