FIELD: manufacture of flexible abrasive tools used in stomatology, as well as in instrumentation engineering, radio engineering, mechanical engineering. SUBSTANCE: to enhance the tool heat stability, resistance to the conditions of sterilization (180 C, endurance - 40 min), preserve the operating characteristics at rotational speeds within 25,000 to 40,000 rpm, enhance the vital capacity of the compound, the latter uses a mixture of polyester and polysiloxan as an organic binder, and a mixture of polythioaceptic base and polyamine - as a curing agent. EFFECT: improved grinding of surfaces of various materials. |
