Ebalta Kunststoff Gmbh GM 727Comp. A+B
- Chemical Family
- Polyurethanes (PU)
Ebalta GM 727 is a well castable two components polyurethane casting resin, curing slowly at room temperature. This casting resin is particularly suitable for solid casting of dimensionally accurate large-volume models with high temperature resistance. Due to low mixing viscosity of GM 727 you can add 70% filler F-B and about 50% plastic granules to reduce shrinkage to approx. 0.05%.

- Processing Instruction
Material- and processing 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.; Follow mixing ratio of resin and hardener according to instructions.; For bubble-free mixing we recommend a star-shaped mixing rod. Stirring rods etc. with residual resin can be easily cleaned with ebaclean.
