Ebalta Kunststoff Gmbh HFGPUR 11
- Chemical Family
- Polyurethanes (PU)
Ebalta HFG / PUR 11 is a light filled 2-components-polyurethane casting compound, which cures fast at room temperature. After curing this material is dimensional accurate light weight but anyway resistant, which is especially suitable for big volume backfilling of coreboxes and negative molds. For bigger wall thickness it is possible to mix about 35 volume parts "Kunststoffgranulat" (=synthetic granules) in comp. A in advance

- Processing Instruction
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. Stirring rods etc. with residual resin can be easily cleaned with ebalta cleaning agent.; Brush gel coat, e.g. OH 11; Gelling of surface; Brush gel coat together with chopped glass strand; Cast comp. B into comp. A; Stir with spiralmixer; Cast immediately
