Mix Instructions:
Adding the curing agent Econosil-25 B processes Econosil-25 A. The addition of 10% catalyst (by weight) has a pot life of 40 minutes and is ready for de-molding after 15 to 24 hours. After the mold has been removed from the master, it should be left for 24 hours in order to develop its maximum mechanical strength.
Use Thix 5170 and PE-ESS-5F (Mini Fibers) to create brush-on low sag rubber bladders. To quick cure Econosil-25, add 2% of FC-200 or Rapid Set at appropriate ratio for a 1-4 hour de-mold time.
