glue for heat resistant insulation for electrical wire
Description :
ZR703 heat resistant insulation for electrical wire , it absorb the moisture in the air at room temperature curing neutral organic silicon sealing material, not heating curing. It for the vast majority of material, have good adhesive sealing performance, protect electronic products in harsh conditions.
Characteristics After Curing:
lAvoid moisture, dirt and other atmospheric composition
lRelieve mechanical, thermal shock and vibration of mechanical stress and tension.
lHave excellent electrical insulating performance.
lOutdoor aging, excellent service life up to 20-30 years
lIn the -60-260 °C it has stable mechanical and electrical properties
lFire resistance
lGlue 3 mm thickness when resistance to 300 °C for a long time
