2018 MARCH 30TH CASTING IMPREGNATION MATERIAL

Durable Features of Hardened Resin

  • Objective:Durability and hardness comparison of UC168 hardened resin
  • Testing:In the short aluminum hose (thick 3mm × width 17mm), cast is full of infusion and placed in 90 ° C hot water heating for 10min. After hardening, hardened resin is cut into 40mm testing pieces.
  • Conditions:Place the testing pieces in all liquids, and immerse for 7 days in the room temperature.

            1.Natural Drying

            2.Oven Drying (100°C × 1hr)

  • Weight Change Rate = (initial weight - measured weight) / measured weight × (100%)
  • Result:
