EP 6476 Epoxied casting resin (quick-curing)

Accessories for connecting elements

  • For cap-sealing connection elements in work areas, storage places and route installations
  • Sealing for optical plug connectors, tension-resistant and tight against pressurised water

General product data


  • Small package: component A 69.3 g and B 20.7 g
  • The low-viscosity material with high mechanical strength has an excellent adhesion to various materials:
    - Plastics: PE, PP, PVC etc., metal casing
    - Strength members made of aramide or glass
    - GFRP pulling and supporting members coated with epoxide, polyester resin or vinylester resin
  • Excellent dimensional stability, even under long-term stress and temperature change
  • Short hardening time (suitable for cap-sealing in works areas, storage places or route installations)
  • Pot life (Processing time): ~ 2-4 min, hardening time: ~ 3 hours
  • Shelf life: 18 months at storage temperature +5 °C to +30 °C
  • Keeps for 18 months, if stored in original sealed package


For speeded-up hardening (at an installation temperature of less than +20 °C), the tin of resin and the metal connector should be warmed up to approx. +25 °C to +30 °C. At temperatures over +35 °C the processing time is reduced to approx. 1.5 min. For good adhesion to materials such as GFRP, it is recommendable to keep the resin tin at a constant temperature by standing it in water or covering it with a damp cloth.

To speed up the hardening process of the resin (at an installation temperature of less than +35 °C) heat the tin and the cable closure to approx. +35 °C. At temperatures over +35 °C the processing time is reduced to approx. 1.5 min. We recommend keeping the resin at a constant moderate temperature (by standing in water or wrapping in a warm damp cloth etc.)



●     Stir the resin thoroughly in the tin.

●     Empty the entire contents of the hardener into the resin tin.

●     Stir both components thoroughly with a wooden stirring rod until the mixture is homogenous (an even greenish colour).



When the instructions for handling the resin mixture in the tin are properly followed there should be no direct contact with eyes or skin. Should this nevertheless occur, wash the affected area immediately with plenty of water as the mixture is corrosive. Eyes are better treated with boracic lotion, though clear water can also be used. Consult a doctor.


Storage and transportation

The product will keep for at least 18 months from the delivery date if kept in a dark, dry place, stored in rooms or containers at a constant temperature of +15 °C to +20 °C.

Technical data:

Quick-drying epoxide resin EP 6476/V01


EP 6476/V1 is a two-component, solvent-free resin with an epoxy resin base. This low-viscosity material hardens in a very short time to form a solid mass with high mechanical strength and good temperature resistance.

EP 6476/V1 adheres well to metals and a range of plastics.



EP 6476/V1 is used for den encapsulating small areas. It is suitable for insulating electrical components, to relieve strain on cables and to provide a tension-resistant seal for optical plug connectors that is effective against pressurised water and gas.

Due to its high thermic stability, it can also be used for encapsulation rotors and stators on small-sized motors.

If EP 6476/V1 is simply used as a glue on non-porous surfaces, it is enough to apply it to one of the surfaces, and no waiting time is necessary before joining them.

Special properties:

For layer thicknesses of less than 1 cm, there may be risk of a violent exothermic reaction (explosion), depending on the surrounding temperature.


Processing tips:

The surface must be clean and free from dust or grease.
Mix components A + B till they form a homogenous mass. To do this, add component B to the containing component A and mix thoroughly. The mixture may also be poured into a clean container for further mixing.

With a thinner.
