SI6715#4 China Superior Clear Elasticity Silicone Gel for IGBT PCB Potting
SI6715#4 China Superior Clear Elasticity Silicone Gel for IGBT PCB Potting
GEL 6715(4#) transparent two-component self-healing silicone gel, after curing to form a buffer, automatic recovery of special soft material. Used to insulate circuit boards from moisture and other harmful contaminants, and to provide insulation against high voltages. Another use is to provide stress relief to protect circuits and interconnectors from high temperature and mechanical stress.
l 1:1 additive molding, strong adhesion, self-healing
l High elongation; Excellent flexibility, eliminating mechanical stress
l Very low oil permeability after curing, excellent resistance to toxicity
l High temperature electrical insulation is excellent, to provide protection against high pressure
l Excellent aging resistance and weather resistance
l Excellent waterproof, anticorrosive, moisture-proof, chemical medium resistance
l It can be used in semiconductor modules, connectors, sensors, etc
Typical Applications
Power semiconductors, electronic sensors, automotive ECU integrated modules and other packaging protection IC chips, power telecommunication waterproof connectors, undersea fiber pooping and so on.
