Processing Instructions

Material- and working- temperature: between 18 - 25 °C.
Close containers after use.
Seal porous mold surfaces first (ebalta mold sealer).
For optimum mold releasing we recommend a special release agent (like T1-1), which can
be applied easily with a brush or be sprayed. Releasing of the mold 2-3 times, evaporate
for about 20 min. after each releasing.
Mixing ratio resin/hardener according to instructions.
Stirring rods etc. with residual resin can be easily cleaned with ebalta cleaning agent
Both components can be easily mixed free from air bubbles in small quantities by hand with a stirring rod or in larger quantities
with a spiral stirrer.
The processing in a vacuum is also possible.
For fast demoulding:
Material temperature: 25 – 30 °C
Molding temperature: 70 °C
Demoulding time: approx. 45 minutes at a mold temperature 70°C and 2 mm thickness
