Dow Corning 3-6121 Low Temperature Encapsulant Elastomer, 5.4kg Kit, Translucent White

ID: DC3-6121X5.4KG Mfr ID: 3-6121-5.4KG
Manufactured by: Dow Corning
Dow Corning silicone 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/electronic applications. Dow Corning silicone encapsulants cure without exotherm at a constant rate regardless of sectional thickness or degree of confinement.

  • Brand name :  Dowcorning
  • Series :  3-6121
  • Item Name :  Encapsulant Elastomer
  • Short Desc :  ELASTOMER,ENCAP.,3-6121 5.4KG KIT
  • UNSPSC :  31201700

Dow Corning silicone elastomers require no post cure and can be placed in service immediately following the completion of the cure schedule. Standard silicone encapsulants require a surface treatment with a primer in addition to good cleaning for adhesion while primerless silicone encapsulants require only good cleaning.
