Technical Bulletin # 665A

The hardener ratio may be varied to optimize the reaction andcure. Note that the resin temperature should be in the range 20-

25C (68-77F).After puncturing the metal foil seal, the hardener bottle is invertedand squeezed to discharge the hardener into the resin container.

The hardener reduction lines are to be read with the bottle invertedas shown.

The maximum amount of hardener possible should normally beused. The graph is for guidance; and the optimum amount willusually be slightly more than it shows. Dispose of excess hardener

in an approved manner and do not collect the remainder of severalbottles in one bottle as it may be mistaken for a complete hardener

unit.
