ebalta GM 979 is an easy-to-handle-2components-polyurethane casting compound which shows very low adhesive properties compared to moulding sand. Due to its high abrasion resistance, GM 979 is especially suitable for foundry patterns, which have to resist to abrasive wear by moulded sand. GM 979 even keeps its high mechanical strength when using moulding sands with higher temperatures. Applications
