Ebalta Kunststoff Gmbh GM 900 1Comp. A+B
- Chemical Family
- Polyureas
Ebalta GM 900-1 / Comp. A+B is a very soft-elastic polyurea casting compound. ebalta GM 900-1 is suitable as a flexible casting system in the field of mold- and tooling for parts which require low shore hardness and high tear propgation resistance due to deep under cuts. Mold temperatures of about 60 °C lead and/or curing at 60°C, to faster curing and therefore short demoulding time. Demoulding can be reduced to 30-40 min

- HIGHLIGHTS
To achieve final properties as fast as possible, postcuring can be made at 60°C for 6-8 hrs. and after curing at room temperature.; For complete curing of the mold, any non-postcured molds should only be employed after 2-3 days.; Any non-observance may lead to shorter pot life. The potlife of GM 951-1 can be shortened by mixing hardener GM 951-1 with hardener GM 900-1 (see mixing table).; For individual formulation of the shore hardness, GM 951-1 can be mixed with GM 900-1 (see mixing table).
- Processing Instruction
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 round stirring rod or in larger quantities with a spiral stirrer.
