Ebalta Kunststoff Gmbh GM 986 1Comp. A+B

GM 986-1 Comp. B (Amine) can be subject to color variations due to raw materials, but these color variations have no influence on the quality and the properties of the product. This material is most suitable for high pressure molding plants with high molding pressure and temperature resistance. For application at 60°C Shore hardness D is between 60-62! The postcured material is not UV stable and darkens by and by. However according to our experience the change in color does not affect its utilizability. As bonding agent on aluminum support we recommend our PU coupling paste KP 8. The material is also dimensionally stable at high temperatures. At a mold temperature of approx. 60°C a Shore hardness D of 62-64 will still be reached. Due to remanent brittleness, for complicated geometries we recommend demoulding after 48 hrs. As bonding agent on aluminum support we recommend our PU coupling paste KP 8.

    Processing Instructions
    • 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 ebalta cleaning agent.

    Important processing instructions:

    • B comp. (amine) must be stirred in and carefully mixed into A comp. (isocyanate). The material must be free of streaks.
    • Before use you have to stirr up / shake the comp. A.
