In order to make the pores in the castings oil free and dry, the castings are washed and dried at 120°C.
Using a vacuum of less than 5 millibar the air is evacuated from the porosity.
After evacuation, the castings are submerged in the liquid resin. Following further evacuation the vacuum is then relaesed.
The IMP-Resin enters the pores of the castings driven by atmospheric pressure. Complete penetration is therefore attained.
The worksurface is washed in a water bath, so negligible surface film is left behind. Further cleaning of the components is not necessary.
The polymerisation of the resin inside the castings is achieved in a hot, water bath at the temperature of 90°C. Using IMP-Resins, bleed out is prevented.
