IOTA 4926 Silicone sealant for new energy automotive safety power
IOTA 4926 Silicone sealant for new energy automotive safety power
Product features:
IOTA 4926 is a kind of double component silicone rubber, room temperature curing, can be heated fast curing. Its characteristics are as follows:
Before curing, good fluidity, the operation time is moderate, good self deaeration, convenient operation and use;
good high and low temperature resistance, after curing can be used for a long time under -50℃ ～+200℃；
good electrical insulation, arc resistance and shock resistance, long time protection of electronic components and welding points；
good thermal conductivity, can guarantee the effective heat dissipation of electronic components and batteries.
Application:
Widely used in new energy automotive power lithium battery PACK, electronic components, waterproof, heat sealing cushion.
Used in various electrical equipment potting, bonding, positioning, sealing and waterproof.
