Ebalta Kunststoff Gmbh GH 705TL 1
- Chemical Family
- Epoxy & Epoxy Derivatives
Ebalta GH 705/TL-1 is a thick-castable, aluminum-filled, heat-resistant, two-components epoxy resin, which shows aluminum-like properties after curing at room temperature. Due to high aluminum contents GH 705/TL-1 shows good thermal conductivity, is well workable and has a low linear expansion coefficient. A thickness of about 30 mm can be casted, by adding massive aluminum granules thicknesses of more than 100 mm can be casted. Maximum thermal stability of thin-wall casting parts is reached after immediate thermal treatment of 12-15 hrs. at 50-60°C after curing at room temperature. The thermal treatment can also be made by slow heating up to working temperature. At a casting thickness of more than 80 mm an automatic thermal treatment happens by formation of heat of reaction.

- 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.
