Iron/Epoxy Casting Resin
PPG C-RAM® KR is a series of two-part castable epoxy resin that remains rigid when cured.
Once cured, PPG C-RAM KR will have the same electrical and physical properties of its counterpart PPG C-RAM RGD.
In general, best performance is obtained at lower frequencies by using a high iron loadings, whereas low loadings work best at higher frequencies. Generally, PPG C-RAM KR-117 and -124 are the preferred grades below 30 GHz.
A non-rusting version of the PPG C-RAM KR material is available in one grade only, denoted KR-115-IS.
PPG C-RAM KR is available in two-part kits in the following sizes:
- 3 lb pint (1.35 kg total weight)
- 6 lb quart (2.7 kg total weight)
- 25 lb gallon (11.3 kg total weight)
Shelf life is at least 6 months when stored in unopened containers. It may be necessary to power stir the contents as settling may occur.
