ebalta GH 781 is a heat resistant two components epoxy resin with very low thermal expansion and high mechanical strength. ebalta GH 781 is suitable to pour on a cast aluminium carrier (sandblast surface). With a thickness of 10-20 mm you get a high quality surface with good thermal conductivity. With hardener GH 781 S a better curing and therefore shorter curing time is reached. For any amendments, repairs and sealings we also have a putty system available. By means of this system together with HRS hardener thicknesses of 5-6 mm can be reached. Applications
