Key Feature of duct silicone sealant                                                      

  

  • 1:1 addition type, good adhesive strength and self-healing 
  • High elongation, excellent flexibility for mechanical stress relieving
  • Low oil penetration after cured, good anti-poisoning property
  • Good dielectric in high temperature for high voltage protection 
  • Excellent aging resistance and weatherability 
  • Excellent waterproof, corrosion prevention, moisture proof and chemical media resistance

Typical Applications of  duct silicone sealant                                          

 

 

Used for encapsulation of various modules, semi-conductorIGBT, automotive ECU module,

 IC chip, weighing sensor, waterproof connector.

 

 Directions for Use                                                                                                                                                                                1. Mix Part A and Part B by 1:1 mass ratio, after evenly mixed, pouring directly into the components 

      or modules as per requirements.

  2. Still the potted component to let out the bubbles. The operation time is short, can cure in a short time, the

      fixture time is about 30 to 40 minutes, potting equipment is recommended for application.

 

  • Vacuum defoaming can improve the performance of cured product.
  • Seal the remaining products tightly after use.
  • Low temperature will slow the curing speed; heat curing is recommended.
  • It's hard for  SI2715-4  to cure if contact with sulfur, amine or Sn
