The GURONIC casting compounds are soft-elastic and offer excellent mechanical damping properties. They ensure reliable protection against vibration and shock, so that only extremely low loads are transferred to components and solder joints. A major advantage of the GURONIC casting compounds is their ability to repair. But also the electrical properties are to be emphasized: good dielectric, very good electrical insulation properties, high dielectric strength, minimal influence of electronic circuits as well as safe operation even at high voltages.
