Properties for Impregnation Epoxy Adhesives

Single part, no mix, solvent free epoxy impregnation compounds are used to seal porosity in metals and non-metals. Compounds offer excellent void filling capability, low shrinkage upon cure and cause no dimensional change to parts being sealed. Powdered metal parts and metal castings including aluminum, zinc, cast iron, steel and magnesium can effectively become pressure tight following vacuum impregnation. This reduces scraps, does not effect appearance, lowers warranty costs and improves profitability. Powdered metal components also will have improved machinability. Additionally, ceramics and plastics can also be protected against porosity.

Our epoxy impregnants seal against:

  • Air
  • Water
  • Oils
  • Solvents
  • Cleaners
  • Coolants
  • Lubricants and much more

Typical applications include:

  • Valves
  • Fuel system components
  • Microwave systems
  • Meters
  • Graphite plates
  • Engine blocks
  • Compressor parts
  • Lens housings

They are also used for:

  • High temperature coils
  • Termination stacks for brushless motors
  • Electronic connectors
  • Thermistors
  • Sensors
  • Wire harnesses
  • Ferrites

After impregnation dielectric properties are frequently enhanced. Master Bond impregnants are known for their unmatched reliability. They are available for purchase in a range of thicknesses and hardnesses.

To achieve the most desirable results considerations should be given to type of porosity material, size, geometry, sealing rate in choosing the proper impregnation process.
