Coping models- Processing Instructions
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.
