☆THEO A.H.E.W.=(THEORETICAL ACTIVE HYDROGEN EQUIVALENT WEIGHT) The physical properties of the cured epoxy resin system will change with different mixed ratio of the hardener. The value listed on the above table is the average value of many datas which are obtained by the different physical properties test at the ambient temperature in the laboratory.							The parts of Hardener by weight to 100 parts of Epoxy Resin(EEW:450~500) The parts of Hardener by weight to 100 parts of Epoxy Resin(EEW:180~200) Brookfield RVT Type; 1mPa.s.=1cP。 Gel Time : Total amount 100g at 20~23℃。 ※ Total amount 200g at 20~23℃ Softening Point : The Softening Point of TOHMIDE 210 is 45℃ determined by Ball-and-Ring method.
