| ebalta GH 730/BR is a quite versatile two-components epoxy resin with good castability, curing at room temperature. Due to its easy workability as well as its high strength and low shrinkage there’s a big variety of applications as mouldmaking, toolmaking and in foundries. Moreover the high impact resistance and cast thickness of more than 30 mm make even more applications possible.
