Ebalta Kunststoff Gmbh GM 973Comp. A+B

The product is a Polyurethane system. For improving of the flow characteristics, GM 973 can be preheated to approx. 30°C. The final strength is achieved at room temperature after approx. 3-5 days. By post-curing at 80°C for 5 hours the stated values are achieved in short time. Parts / molds must not be cast with addition curing silicone, since this might lead to faulty reactions when curing the silicone.

    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.
    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.
    The processing in a vacuum is also possible.
    Stirring rods etc. with residual resin can be easily cleaned with ebalta cleaning agent
