Due to the crack-free hardening, this embedding resin is preferably used unreinforced as casting resin. It hardens largely without shrinkage and with a tack-free, glossy surface.
For artistic and decorative applications, e.g. embeddings, sprues and river tables. Suitable for embeddings are metals (coins, electronic components), inorganic (shells, stones) and organic preparations (plants, insects). The preparations should be dry.
Room temperature is the most important parameter for successful processing of the Resin CRYSTAL-CLEAR. There is a relationship between room temperature (RT), the volume of resin poured and curing speed. Rapid curing caused by high room temperature results in a high exothermic reaction. The cured resin can then form cracks and shrink, especially in the corners.
Thoroughly mix the two components by hand or using a mixing propeller/drill. Care must be taken not to stir in too much air.
After the first mixing, pour the material into a second container and mix again. Allow the mixture to stand for at least 15-30 minutes for self-deaeration before pouring.
Due to the long pot life and low viscosity, the casting frame must be completely tight. Use a release agent as Partall® Hi-Temp Wax or PE packing tape.
After pouring and short resting time of the material, remaining bubbles can be easily removed with a hot air blow dryer.
For a shiny and smooth surface, light sanding and polishing or painting of the surface is usually necessary.
At least 12 months in closed containers at 15-25 °C.
After prolonged storage at low temperatures, crystallization of the A-component (resin) may occur.
This is easily removed by warming up for sufficient time to a maximum of 70 °C.
