Iron/Silicone Casting Resin

PPG C-RAM^® KRS is a series of two part liquid RTV silicone casting resin kits which can be used to mold wave guide terminations, attenuators, loads, RF gaskets and other radar absorber parts. When cured, the material converts to a flexible, high temperature silicone rubber.

Parts cast from PPG C-RAM KRS have the same performance as parts machined from sheets of PPG C-RAM RGD-S. PPG C-RAM KRS is available in the same grades as PPG C-RAM RGD-S.

A non-rusting version of the PPG C-RAM KRS is available in one grade only, denoted KRS-115-IS.

PPG C-RAM KRS will cure and adhere to itself or to other silicone surfaces, however, it will release from most substrates. If adhesion is required, a primer must be used.

PPG C-RAM KRS 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 12 months when stored in unopened containers. It may be necessary to power stir the contents as settling may occur.

Completed machined pads are available as PPG C-RAM RGD-S.
