Chlorobutyl Lining EC Duro-Bond Chlorobutyl Sheet Lining Description EC Duro-Bond Chlorobutyl is an uncured chlorobutyl elastomer applied in sheet form and vulcanized after application using exhaust steam. Sheet thicknesses of 120 mils (2.3 mm), 150 mils (3.4 mm), and 180 mils (4.6 mm) are available. Uses Duro-Bond Chlorobutyl is used as a lining for tanks, valves and other equipment where chemical and heat conditions require a special lining. It is used primarily for handling specific acids at high concentrations such as hydrofluoric acid at 70%. Advantages EC Duro-Bond Chlorobutyl exhibits excellent abrasion and corrosion resistant properties. The lining is applied while in the soft uncured state. It readily conforms to curved surfaces allowing it to be applied to a wide variety of equipment with complex shapes. Service Temperature The maximum temperature for which Duro-Bond Chlorobutyl is recommended is 180oF (82oC). However, it can withstand higher intermittent temperatures. In constant elevated temperatures elastomers can harden and age prematurely, resulting in cracks and lining failure. It is sometimes desirable to provide thermal insulation, thereby increasing the service life of the lining. Corrosion resistant shale, fire-clay, or carbon brick are generally used for this purpose. One or more courses of brick joined with one of the Electro Chemical corrosion resistant cements may be required to obtain the desired temperature reduction. Chemical Resistance The information listed may be considered as a basis for recommendation, but not as a guarantee, unless sold and installed by Electro Chemical Engineering & Manufacturing Co.

Flammability Burns and supports combustion Color Black Abrasion Resistance Excellent Application The installation of Duro-Bond Chlorobutyl sheet lining is described in the following steps: 1. The metal surfaces are sand or grit blasted to a white metal finish. 2. One coat of primer is applied immediately after blasting metal to prevent rusting. Additional coats of primer are applied, if necessary. CHLOROBUTYL Lining.doc Page 4 of 5 Electro Chemical Duro-Bond Chlorobutyl Lining 3. The required coats of intermediate or tie cement are applied allowing sufficient drying time so that the coat being applied does not lift the preceding cost. 4. Edges of all sheets are skived at an angle from the top surface to the bottom of the sheet. 5. The Duro-Bond Chlorobutyl sheet is wiped with the recommended solvent and allowed to dry before application. The Duro-Bond Chlorobutyl sheet is then applied using the minimum number of seams consistent with good lining practice. Edges should overlap approximately 2" unless restricted by dimensional tolerances. During application, sheets are rolled and all seams and corners carefully stitched to eliminate all trapped air between lining and cemented surfaces.

EPA staff also note where changes to approvals are needed. Where those changes are not minor or technical, these changes require a reassessment or a modified reassessment of the approval of the substance under the HSNO Act 1996 (“the Act”) The Chemical Review is intended as a means of making changes to a number of approvals at once, taking into account the new information available to the EPA. This is undertaken as a modified reassessment under section 63A of the Act. This application makes recommendations to change some or all of the following aspects of the approvals in this application: - The approval name of the substance - The hazard classification(s) applied to the substance - The controls applied to the substance The controls changes proposed are largely as a result of changes to the hazard classifications of the substances in this application.

    50th International Conference on Environmental Systems ICES-2021-292 12-15 July 2021 Experimental Proof of Concept of a Cold Trap as a Purification Step for Lunar Water Processing Jordan B. Holquist1, Sean Gellenbeck2, Chad E. Bower3, and Philipp Tewes4 Paragon Space Development Corporation, Tucson, AZ 85714, USA Since the observation of direct evidence of water-ice in the permanently shadowed regions (PSR) on the lunar surface, in-situ resource utilization (ISRU) has been proposed for processing the regolith-bound water-ice to provide fresh water, breathable oxygen, and liquid rocket propellant for lunar exploration missions. One possible method of extraction is the sublimation and vapor transport of the water from the regolith to a collection and processing system. However, the water-ice is found concurrently with other typically volatile species that can sublimate with water vapor and that would contaminate and degrade downstream processing systems. Paragon Space Development Corporation® is developing the ISRU- derived water purification and Hydrogen Oxygen Production (IHOP) system to collect, purify, and process water-ice from PSRs on the lunar surface. A critical component of this system concept is a cold trap that selectively deposits water-ice from a saturated water vapor stream while rejecting the contaminant volatiles. This paper presents results, analysis, and discussion of an experimental proof of concept demonstration wherein a warm process gas containing water vapor and volatile contaminant components (H2, CO, H2S, NH3, SO2, C2H4, CH4, CO2, and CH3OH) was passed into an evacuated and actively chilled thick-walled glass bottle. Water-ice samples were collected from each of eight test batches with varying contaminant components present at concentrations with respect to water vapor matching their observed proportionality from the LCROSS mission results.

Title III of SARA, known as the Emergency Planning and Community Right-to-Act, sets requirements for hazardous chemicals, improves the public’s access to information on chemical hazards in their community, and establishes reporting responsibilities for facilities that store, use, and/or release hazardous chemicals. RQ = Reportable Quantity. An amount entered in this column indicates the substance may be reportable under §304 of SARA Title III. Amount is in pounds, a "K" represents 1,000 pounds. An asterisk following the Reporting Quantity (i.e. 5000*) will indicate that reporting of releases is not required if the diameter of the pieces of the solid metal released is equal to or exceeds 100 micrometers (0.004 inches). TPQ = Threshold Planning Quantity. An amount entered in this column reads in pounds and indicates the substance is an Extremely Hazardous Substance (EHS), and may require reporting under sections 302, 304 & 312 of SARA Title III. A TPQ with a slash (/) indicates a "split" TPQ. The number to the left of the slash is the substance's TPQ only if the substance is present in the form of a fine powder (particle size less than 100 microns), molten or in solution, or reacts with water (NFPA rating = 2, 3 or 4). The TPQ is 10,000 lb if the substance is present in other forms. A star (*) in the 313 column= The substance is reportable under §313 of SARA Title III.
