    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
    For face-casting application of the resin the riser diameter has to be up to casting thickness.
    By adding our thixotropic agent 72 the product can be applied with brush.
    Our product HV 55 serves both as adhesive and coupling agent.
    For concrete casting we recommend our concrete release agent B3.
    Avoid any application of mineral spirit-conatining concrete release agents.
