Note:The operation time was results based on testing 100g mixture; curing condition data was tested under 25°C,55%RH.

Adjusting the mix ratio of Part A and Part B would affect the hardness of the gel. (Increase the mass of Part B, will improve the penetration of the gel, the gel becomes softer and better adhesion; on the contrary, decrease Part B, the penetration of gel becomes less, the gel becomes stiffer with less adhesion.)


 
 

 

Key Feature of silicone sealant                                                                

  

  • Solvent free two component material
  • Transparent both before and after cured
  • Platinum catalyzed curing system
  • No by-products after curing
  • Low viscosity before cured, easy to application
  • Excellent flexibility, free from stress
  • Extremely low oil exudation, good anti-poisoning
  • By adjusting the mix rate of part A and part B, can adjust the gel adhesion
  • It can stick repeatable
  • It can use with polyethylene release liner
  • Pass test of physiological compatibility, poison cell, skin stimulus etc.

  • Mix Part A and Part B by 1:1 mass ratio, after evenly mixed, pouring directly into the components or modules as per requirements.
  • Still the potted component to let out the bubbles. It can be cured by heat, about 30mins in 80°C. It needs about 6 hours cured under room temperature.

 

  • 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 forSI2721to cure if contact with sulfur, amine or Sn
