ZR706 microwave oven special sealing glue, it absorb themoisture in the air at room temperature curing neutral organicsilicon sealing material, not heating curing. It for the vastmajority of material, have good adhesive sealing performance,protect electronic products in harsh conditions.
Characteristics After Curing:
1. Avoid moisture, dirt and other atmospheric composition
2. Relieve mechanical, thermal shock and vibration of mechanicalstress and tension.
3. Have excellent electrical insulating performance.
4. Outdoor aging, excellent service life up to 20-30 years
5. In the -60-260 °C it has stable mechanical and electricalproperties
6. Fire resistance
