MATERIAL - STRUCTURAL POTTING COMPOUND: FOAMED-IN-PLACE, EPOXY-PHENOLIC RESIN TYPE - QUALIFICATION OF
Abstract
Three types of Thermofoam 607 are in use. The composition and proportions of these are given. Information was needed to verify Convair's proposed specification FMS-0076 for foamed-inplace structural potting compound of the epoxyphenolic resin type; hence this test was originated to substantiate known characteristics and properties of Thermofoam 607 (types I, IA, and II) and to establish requirements for future acceptance testing of this material. Of all the compression specimens tests, only one went below the proposed minimum values. It was noted that at least one sample of each type of Thermofoam did not meet the density requirement; hence the proposed specification may need to be changed to comply with the test results. The cellular structure of the foam as stipulated in the proposed FMS-0076 (1/4 inch maximum, 1/16 inch average voids) was satisfactory. However, some variation existed in the different lots of material which resulted in varying densities with the same types of foam. Generally, as the density increased the compressive strength was proportionally increased. Adhesive Engineering's Thermofoam 607 meets the requirements of the proposed Convair Specification FMS-0076 except for the density requirement.
