LOCTITE IS 5110

LOCTITE IS 5110 is a one-component, low-viscosity anaerobic sealant for vacuum impregnation of interfacial leak paths in rigid electronic assemblies. Its typical viscosity is 36 to 66 mPa s at 25 deg C, allowing liquid sealant to saturate internal porosity during vacuum impregnation. Excess material disperses in water and is rinsed from exterior surfaces before the retained sealant cures in the absence of freely available oxygen. The cured thermoset has Shore D 89 hardness, volume resistivity of 9 x 10^13 ohm cm, and a continuous-temperature design limit of 205 deg C. Applications include overmolded components, connectors, coils, lamination stacks, solenoids, and sealed enclosures.

Key features

• Low-Viscosity Vacuum Impregnation: Typical viscosity is 36 to 66 mPa s at 25 deg C for the vacuum-impregnation process.
• Water-Dispersible Excess Sealant: Excess liquid disperses in water for post-impregnation rinsing from exterior surfaces.
• Anaerobic Internal Cure: Sealant retained inside porosity polymerizes where freely available oxygen is absent.

Applications

Vacuum impregnation and leak-path sealing in overmolded electrical components, connectors, high-temperature coils, lamination stacks, solenoids, and sealed enclosures.
