Ebalta Kunststoff Gmbh LH 28 1TM
- Chemical Family
- Epoxy & Epoxy Derivatives
Ebalta LH 28-1 / TM is a two components epoxy laminating resin, precuring at room temperature and, depending on postcuring, can be used till 175°C. Since this laminating resin system contains no fillers, it has got good wetting properties and makes a high glass fabric content possible. This leads to a low coefficient of thermal expansion and high strength. Together with aluminum granules, ebalta LH 28-1 is suitable for back filling of heat resistant molds and molding tools. At room temperature the curing takes 7 days and the material can only be used for applications till 60°C.

- Storing
At appropriate storage 18-25°C. Occuring crystallization due to disadvantageous storage conditions can be made return by warming up the material at approx. 60° C for some hours. Opened containers should be closed immediately after use and be protected against moisture. This material should be used up as soon as possible. Shelf life is indicated on the labels

- We recommend to perform the complete postcuring on the master model , at least the first one should be made this way.

- Processing Instruction
The temperature of material and processing should be between 18 and 25° C. The mixing of resin and hardener should be made intensively and if possible without any bubbles at room temperature. We recommend a post curing with a temperature rise of about 10°C/hour. Difficult geometries should be supported during the curing cycle. Afterwards the part should be cooled down at about 20°C/hour.
