8030-01-324-4457 UI: LBCOATING COMPOUND: DESCRIPTION In accordance with Military Specification MIL-C-81904, Coating Compound, Thermal Insulation, Ablative, dated May 31, 1991 and Amendment 1, dated August 24, 1992. QPL qualification required. Component A only: polyester base resin Color: ghost gray, FED-STD-595 Color 36375 Size: The product shall be furnished in 590 lb quantities in new, straight-sided, cylindrical, steel drums of the type normally used for this product provided that there will be no interaction chemically or physically with the contents so as to damage the container or alter the strength, quality, or purity of the contents. The filled drums shall be closed in a manner that will insure that the contents will not spill or leak from the containers during shipment, handling, storage, and redistribution. The drums shall, as a minimum, meet the applicable requirements of the National Motor Freight Classification, Uniform Freight Classification, and Department of Transportation regulations. Shelf life code: 1 (3 months) Maximum age on delivery: 21 days EXCEPTION(S) TO TECHNICAL DOCUMENT 1. Remove MIL-P-87938 as an applicable document under Military in Paragraph 2.1.1. 2. Change paragraph 3.4.2 as follows: 3.4.2 Component B (Catalyst). Component B is a composition of methyl ethyl ketone peroxide containing glycerine. The glycerine content shall not exceed 9% by weight of the solution. The component B shall conform to the requirements as stated below: PRESENT TABLE 3. Add Paragraphs 4.6.3, 4.6.3.1, 4.6.3.2, and 4.6.3.3 as follows: 4.6.3 Component B (Catalyst) Tests. 4.6.3.1 Active Oxygen. The active oxygen content shall be determined using the following method: Thoroughly mix the solution prior to withdrawing samples. Prepare glass stoppered 125 ml Erlenmeyer flasks by adding 20 ml of glacial acetic acid then passing carbon dioxide into the acid in each flask for two minutes. Weigh to the third decimal point approximately 0.2 gram samples into these flasks. Add 10 ml of KI solution (10 grams KI in 20 ml water) and let stand in the dark for 15 minutes. Add 10 ml water, and titrate with 0.1N sodium thiosulfate to colorless endpoint. A blank shall also be run and subtracted from the sample titration before calculation. %Active Oxygen = [(ml thio - ml blk) x N x 0.008 x 100]/sample weight; N = normality of sodium thiosulfate solution. 4.6.3.2 Specific Gravity. Specific gravity shall be determined in accordance with ASTM D 891. 4.6.3.3 Refractive Index. Refractive index shall be determined in accordance with Method 4371 of Federal Test Method Std. No. 141. 4. Renumber present paragraphs 4.6.3 through 4.6.12. 5. If previously qualified product has changed manufacturer, the current manufacturer shall certify that the original qualifying product and formula has not been changed.
