Ebalta Kunststoff Gmbh GH 723D
- Chemical Family
- Epoxy & Epoxy Derivatives
ebalta GH 723/D is a very well castable two-components epoxy resin, which, after curing at room temperature, can be worked on well with tools for metalworking. This system is a most suitable back cast resin for molds of which the back has to be worked on mechanically after curing. For back-casting round aluminum granules are used, for bulking: rough aluminum granules. Since the resin/hardener mixture is very liquid, a 50-100 weightcontent of fillers like aluminum granules or silica sand has to be added to get a back-cast mass of 100-200 mm thickness. Under normal circumstances a thickness of 40 mm can be reached with GH 723/D.

- Processing Instruction
The temperature of material and processing should be between 18 and 25° C.; Filled systems should be stirred thoroughly before use.; After each use the containers have to be closed again.; Porous mold surfaces should be sealed before ( ebalta sealant ).; For an optimum mold release we recommend a suitable release agent (e.g. T 1-1) which can be easily applied with a brush.; The mold should be treated 2 or 3 times with release agent and allowed to evaporate for approx. 20 min after every application.; Mixing ratio resin/hardener according to instructions!; To get a clean component part , we recommend upward flow casting and to take care of sufficient venting.; Resin residues at stirring rods and so on can be easily cleaned with our ebaclean.
