DOWSIL™ EE-3200 Low Stress Silicone Encapsulant

Has a very low hardness and viscosity to minimize internal stress generation, fill small gaps, and improve manufacturing speed for complex and high volume electronic devices.

Benefits:

  • Low modulus reduces pressure on components
  • Thermal conductivity effectively dissipates heat
  • Good mechanical adhesion avoids delamination issues
  • Fast cure and optimized working time allows for more complex designs and lower module cost
  • Dielectric strength and volume resistivity reduce costs as no additional dielectric barrier is required
  • Ease of use – low viscosity allows fast fill and fit with high throughput manufacturing processes
  • Minimal filler settling allows for ease of process control
  • Meets certification requirements

Lower system cost using more reliable encapsulants that protect longer against tough climatic conditions

DOWSIL™ EE-3200 Low Stress Silicone Encapsulant combines the stress relieving properties of a gel with the thermal conductivity of an encapsulant.

This material is successfully proven in solar inverters, where it provides best-in-class protection of sensitive components against repeated thermal and mechanical stress, as well as moisture and other punishing environmental factors. Using silicone encapsulants help solar manufacturers to achieve higher system value and lower system costs.

The features that make this material so successful in solar inverter application, make it an ideal and proven material for other applications with similar requirements.

In addition, DOWSIL™ EE-3200 Low Stress Silicone Encapsulant solves the issue of thermally induced stress.
