D4926 Two-component silicone sealant
Details
D4926 Two-component silicone sealant
Product features:
D4926 is a kind of double component silicone rubber, which is cured at room temperature and can be heated quickly. Its characteristics are as follows:
Before curing, good fluidity, the operation time is moderate, good self-decoration, convenient operation and use;
good resistance to high temperature and low temperature performance, after curing can be used under -50℃~+200℃;
good electrical insulation, arc resistance and shock resistance, long time protection of electronic components and welding points;
Good water resistance, ozone resistance, earthquake resistance, aging resistance, can effectively prevent the infiltration of water vapor, to maintain long time sealing performance;
good thermal conductivity, can guarantee the effective heat dissipation of electronic components and batteries.
Application:
Widely used in the new energy automotive power lithium battery PACK, electronic components, waterproof, heat sealing cushion;
Used in various electrical equipment potting, bonding, positioning, sealing and waterproof.
