Low Out-Gassing WaveGuide RF / Microwave Absorbers & Dielectrics
AA-BOND CR-112 can be used to mold waveguide terminations, attenuators, and loads to size. CR-112 can also be used to precisely pot small amounts of absorber in or around areas of RF leakage.
AA-BOND CR112 is a two-part castable load absorber epoxy system.
AA-BOND CR112 has good physical and mechanical properties plus superior wetting and handling characteristics.
AA-BOND CR112 is specialty designed to mold the waveguide terminations, attenuators and for potting of the absorbers in or around the areas of RF leakage.
AA-BOND CR112 mixture will have a longer pot life and exhibit high deflection temperatures, the exotherm during the cure is low and allows the casting for larger parts.
AA-BOND CR112 provides very good resistance to water, weather, jet fuels, most petroleum products, salt solutions, mild acids and alkalis, and many other organic and inorganic compounds.
For safe handling information on this product, consult the Safety Data Sheet (SDS).
HOW TO USE:
1. Carefully clean and dry all surfaces to be bonded.
2. Warm the part A (RESIN) of AA-BOND CR112 at 30°C to 40°C to reduce the viscosity and improve the pourability of the epoxy.
3. Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best result.
4. Mix the part A with the part B until homogenous mix and apply.
This epoxy can be supplied in many different packages.
