Eccosorb®CRS
• It does not ship as a dangerous good.
• Shelf life is approximately 6 months when stored unmixed in a well sealed container at
temperatures no higher than 25°C (77°F).
INSTRUCTIONS FOR USE
• Mix the Eccosorb CRS Part A in its shipping container using a power stirrer to insure
homogeneity.
• Part A is supplied as a high viscosity paste. In all cases a small amount of Part B has to be
added.
• Weigh out the desired amounts of both parts in the correct mix ratio as given below.
Mix ratio : Eccosorb CRS-117: 100 parts of A to 1.18 parts of B
Eccosorb CRS-124: 100 parts of A to 1.00 parts of B
• To insure void-free castings, the entrapped air should be removed by vacuum de-airing.
• Pour into the cavity to be filled.
• Cure overnight at room temperature or for 3 hours at elevated temperatures of 80°C (175 °F).
Where use temperature is anticipated above 120°C (248 °F), a post cure is recommended.
Gradually raise cast parts to the use temperature over an 8 hour or longer period.
• If cast around inserts, they place negligible curing pressures on them.
• The Eccosorb® CRS will adhere to themselves but will release from most other surfaces.
Therefore, metal or epoxy molds are suitable for cast shapes. If adhesion is required, a thin
coat of a suitable primer should first be applied.

*Note: Attenuation is a theoretical property calculated from the Complex Permittivity and Complex Permeability of a lossy material and is strictly a means of comparing one absorbing material to another.
The attenuation properties are not an indication of how the material will perform inside a microwave device. For further electrical and physical properties of the ECCOSORB^® CRS series, please see the Typical
Electrical Properties Table on the ECCOSORB^® MFS technical bulletin
