| ebalta GH 760/GL is a two-components epoxy resin, curing at room temperature, castable to 40 mm. The fine non-grinding fillers lead to good surface slip properties and mechanical workability. For this reason ebalta GH 760/GL is especially suitable for metal sheet tools as well as for foundry equipment. Due to its high strength and excellent dimensional accuracy this system is quite versatile. Applications Foundry patterns Core boxes Boards Control castings jig Hammer form tools Stretch forming tool Stretch tools Properties dimensionally accurate abrasion resistant high strength castable until 40 mm very good sliding properties&& |
