ECCOSORB CR ECCOSORB CR Two-Part Castable Load Absorber Series Material Characteristics Typical Properties Castable epoxy resin that remains rigid when cured Service Temperature, F (C) <356 (<180) ECCOSORB CR will duplicate the physical and electrical properties of its counterpart in the Specific Gravity 1.6 to 4.6 ECCOSORB MF series. For example, ECCOSORB -6 Thermal Expansion Coefficient (C) 30 x 10 CR-117 is the equivalent to ECCOSORB MF-117 Frequency range from 1 - 18 GHz 6 Izod Impact, ft-lb/in of notch (ergs/cm) 0.3 (1.6 x 10 ) Dark Gray in color Water Absorption, %, 7 days immersion 0.1 Low out-gassing properties for space applications 2 Flexural Strength, psi (kg/cm) 15,000 (1050) %TML 0.08 - 0.51 Applications %CVCM 0.001 - 0.01 ECCOSORB CR can be used to mold waveguide terminations, attenuators, and loads to size Shelf Life at temp. no higher than 77 F 6 months ECCOSORB CR can also be used to precisely pot small amounts of absorber in or around areas of RF leakage Recommended Frequency and Shipping & Availability Mixing Ratios by Weight ECCOSORB CR is available in six castable versions, Series Range (GHz) Part X Part Y CR-110, CR-112, CR-114, CR-116, CR-117, & CR-124 ECCOSORB CR is supplied as a two part system CR-110 26+ 100 12.0 consisting of a Component X and Component Y in 2 CR-112 12 - 18 100 8.2 pound (quart) and 5 pound (gallon) kits Both CR-117 and CR-124 are available in premixed CR-114 10 - 14 100 4.8 and frozen 5cc, 10cc, and 30cc syringes. No Mixing is CR-116 6 - 12 100 3.0 needed. Note: Premixed and frozen packaging requires storage at 40F (-40C) and shelf life is 3 CR-117 4 - 8 100 2.3 months. Minimum buy is 100 syringes for any size. CR-124 5 and below 100 2.0 Component Y ships as a hazardous material: Class 6.1, UN1673, P/G III Recommended Cure Schedule Instructions for Use Temperature Cure Time Prepare mold by applying a thin coat of butchers wax Mix Part X in its shipping container to a uniform 165F (74C) 12 hours consistency before removing any material 200F (93C) 4 hours If crystals appear in Part Y, gently heat to 150 F until crystals go into solution 250F (121C) 2 hours Weigh out the desired amounts of both Part X and Part 300F (149C) 1 hour Y in accordance with the table at right Heat Part X to about 150 F. This will reduce the viscosity substantially and improve pourability. Note: in an effort to drop viscosity do not dilute with any chemical as this would alter the electrical performance of the material Thoroughly blend Part X and Part Y. Remove entrapped air, if necessary, by vacuum evacuation Pour into mold (pot life at 150 F is about 1 hour) and cure per the below schedule. The mold is also preferably preheated to about 150 F Clean up can be done with a solvent such as MEK EMERSON & CUMING MICROWAVE PRODUCTS, INC., 28 York Avenue, Randolph, MA 02368 / Telephone (781) 961-9600.
