Dow silicone 10 to 1 encapsulants are supplied as two-part liquid component kits. When liquid components are thoroughly mixed, the mixture cures to a flexible elastomer, which is well suited for the protection of electrical/PCB system assembly applications. Dow silicone encapsulants cure without exotherm at a constant rate regardless of sectional thickness or degree of confinement.


  • Flowable
  • Room temperature and heat cure
  • Good dielectric properties
  • Rapid, versatile cure processing controlled by temperature
  • High transparency allows easy inspection of components


The 10 to 1 mix ratio these products are supplied in gives one latitude to tune the modulus and hardness for specific application needs and production lines. In most cases de-airing is not required.
