General description

Two parts polyurethane potting resin.

Application

Casting resin for encapsulation of transformers, printed circuit board assemblies, inductive components ...

Processing

The resin must be stirred before use, as it contains fillers which may settle during storage. Avoid air introduction during stirring.

Polyurethane resin and hardener are sensitive to moisture during the processing steps (storage, mixing, casting). The parts to be

casted shoud be dry and clean.

A preheating of the parts and/or of the resin may improve the encapsulation. A vacuum processing enhance the dielectrical and

mechanical properties.

Mixing can be done by machine or manually.

The gel time and the curing time depend on the mixed volume, the temperature and the thickness of the layer.

Final properties are depending on the curing level.

Mixing ratio (resin/hardener):

Weight: 100 / 16

Volume: 100 / 20

Storage Conditions

Resin : 12 months in original packaging, at maximum 25°C, protected from moisture. Possible storage at higher temperature for

short period of time. A storage above 25°C will increase the settling.

Hardener: 12 months in original packaging, at maximum 25°C, protected from moisture. Possible storage at higher temperature for

short period of time. May crystallise below 5°C. In such case, warm up to 60°C until crystals disappear, and stir before use.

Packaging

Resin : 25 kg, 250 kg metallic drums,

Hardener : 5 kg, 25 kg, 250 kg metallic drums,
