Ebalta Kunststoff Gmbh GM 708PUR 4
- Chemical Family
- Polyurethanes (PU)
GM 708 is a high-quality, almost odorless 2-components-polyurethane casting compound without any filler. The filler will only be added when mixing both components. The long potlife of more than 45 min makes it possible to cast big-volume parts. Depending on the application, different dry fillers can be used. To get optimum properties, especially low shrinkage, we recommend a high filler content.

- 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.; Mixing ratio resin/hardener according to instructions.; Stirring rods etc. with residual resin can be easily cleaned with ebaclean.
