SDPpotting EC 4920

DIELECTRIC RESIN

The SDPpotting EC 4920 system is a dielectric polyurethane resin with Shore A 80 hardness, a two-component system used to encapsulate, protect, and immobilize electronic components on a circuit board or in a housing. The main functions of the SDPpotting EC 4920 system are: • Mechanical protection against shocks and vibrations. • Electrical insulation that secures the circuit and prevents short circuits. • Protection against moisture and corrosion of electronic components.

Applications SDPpotting EC 4920

The SDPpotting EC 4920 system is a flexible two-component dielectric polyurethane resin used to encapsulate, protect, and immobilize electronic components on a circuit board or in a housing.

The main functions of the SDPpotting EC 4920 system are: 

  • Mechanical protection against shocks and vibrations
  • Electrical insulation that secures the circuit and prevents short circuits
  • Protection against moisture and corrosion of electronic components


The main characteristics of the SDPpotting EC 4920 system are:

  • Very low reaction exotherm
    • No damage to components, ideal for thick parts.
  • Very low curing shrinkage: maintains circuit integrity.
  • Excellent electrical insulation.
  • Excellent resistance to moisture and chemicals
  • Shore A 80 hardness,
    • Good resistance to shocks and vibrations


The SDPpotting EC 4920 system is a two-component product designed to be processed using a low-pressure casting machine or, depending on the application, manually.

The SDPpotting EC 4920 Polyol is a composition based on polyether and polyester polyols, and 100% reactive catalysts.

The isocyanate is a modified MDI.
