REFRACTORY ^ .INSULAliUN lUkrui^iiuw ' UTILITY THERMAL FINISH CEMENT Utility Thermal Finish Cement is composed of high quality mineral fiber, hydraulic binders, and other suitable materials. Utility combine s the flexibility, high temper ature resistance, and excellent insulating qualities of uniformly nodulated mineral fiber with the strength, low shrinkage, and smooth finish of hydraulic setting cement. The result is a quick setting, smooth finish,, thermal resistant, single layer insulating finish cement. For temperatures .up- to 1200F. . ' QUICK SETTING Utility Insulatin_ x-'inish Cement develops a smooth, durable, protective finish within a . few hours after application and without the presence of heat. Subsequent drying proouces no excessive surface cracking or shrinkage in thickness, and occasional wetting does no damage after hydraulic set.. Long drying periods under normal conditions are eliminated. Saves time in applying weatherproofing, paint, or other finishes. Jobs are easier to schedule; scaffolding costs "are reduced. ONE COAT APPLICATION Utility is normally applied in a single layer application. A second layer is needed only when multiple layer thicknesses. are specified. Utility is virtually an all -purpose insulating finish cement, designed primarily for use over Griptex block or blanket insulations. Utility is widely used for insulating valves, fittings, heated equipment, and as an anti-sweat insulation for cold water tanks, pumps, etc. ^ `. Utility trowels with a good key on block insulation; blanket insulation and insu- Tatirig cement. It has good wet adhesion to clean steel surfaces, such as valves and fittings. .` . . .. ^_ PLEASING APPEARANCE -- . Utility dries to a smooth, light reflectant surface which as an interior finish, requires no further treatment. Utility, however, is easily painted if desired. Outdoor applications should be weather protected. Low temperature applications require a vapor seal type finish. - EXCELLENT THERMAL QUALITIES . Utility has a "K" factor of . 79 atbOOF.mean temperature. This excellent insu lating value as compared to other finish cements is a very desirable advantage when figuring job and operating costs.

' Gunfrf": I ' SUPER 711 Insulating Cement is a mixture of high temperature mineral fibers specially processed into resilient wool nodules, combined with asbestos and suitable binders to form a high temperature plastic insulation. Water added according to directions gives a trowelable consistency that is ready for application on equipment to be operated at temperatures up to 1800F. WIDE USAGE SUPER 711 is a versatile material for many types of insulation requirements. Applied over block or blan ket insulations, it fills open joints and provides a mono lithic surface for whatever type of subsequent finish is specified. Its plastic flexibility permits application directly to regular or curved surfaces -- such as valves, fittings, tanks and vessels. EASY TO APPLY ' SUPER 711 has excellent adhesive qualities. Its increased stickability means a better job in less time, from wet to dry. Will not slip or roll under trowel appli cation and may be easily gun applied. This superior workability is aresult of fine mineral nodules, special manufacturing methods, and quality control. MAXIMUM COVERAGE - LOW SHRINKAGE ' ' ' SUPER 711 Insulating Cement assures maximum coverage and low shrinkage. The resilient nodules of mineral fiber do not collapse when mixed with water.

Remove dirt, scale or loose paint from the surface to be treated, then apply rust preventative paint or coating when specified. 2. For trowel applications to columns and beams, form 3/8" rib lath (or paper-backed lath) to box-in the member. Apply rib `lath with ribs turned in and spanned from flange to flange. On members 14" and * larger, first weld 1/4" rods across the flanges approximately 12" to - 18" on centers to provide additional support for the lath. Secure the lath in place with wire or bands. For gun application, use 2x2 #16 paper-backed*lath such as Steeltex. - a) ' Provide 2"firestops on columns at 8' to 12* intervals (or as other wise specified). Form the metal lath into a horizontal shelf ex tending to and supported at the weo. Apply Pyroscat 2" thick in the opening. Provide similar stops at the top elevation of the fire proofing. - b) Plasterer's corner bead may be wired to the metal lath, forming and supporting.it to attain the total Pyroscat thickness specified. Corner bead shall be of the type having opeh-mesh legs to facili- . tate complete filling of the corners. The corner bead may be spaced the proper distance from the flanges by means of corner clips, rods, studs; or Pyroscat may be spotted-in to space the ' corner bead at specified fireproofing thickness. B. Application of Pyroscat ` 1. Mix P^yroscat to recommended consistency with clean, fresh water, before application. Refer to mixing instructions on the bag and use no more water than called for. Mix Pyroscat to a homogeneous plastic mass; avoid over-mixing, particularly with mechanical mixers. a) Apply Pyroscat well into the metal lath, installing approximately . 1/2 the total thickness in the scratch coat. Leave the first coat ` rough or scratch the surface. , b) On the underside of beams, the application may be in three coats. , Apply a thin scratch coat first to improve adhesion. '. c) If corner bead was not applied previously, wire it in place when the scratch coat has set. 2. Let the scratch coat harden until well set (4 to 6 hours or longer), then double-back with the finish coat. Apply it flush with the corner bead. Sponge-float the surface to a textured finish or as otherwise specified. a) When application of the finish coat is deferred over night or longer, wet down the scratch coat thoroughly before proceeding with thp finish coatt (r May, 1964 % C. .. Curing Pyroscat ; '1, ' Pyroscat is a cementitious material; to develop its strength, keep it moist for 72 hours or longer. Depending on atmospheric conditions when applied, the required water retention may be accomplished with wet burlap, periodic water spray or a hydrostatic (resin-base) sealer. 2. Following the curing period and when visual moisture has dried, apply a suitable flashing material at all intersecting joints and exposed ends of members treated (Duriseal T-178 Coating). .. * 3. Pyroscat may be painted with (1) masonry paint, (2) two coats of asphalt- base aluminum paint, or (3) other finishes as specified for operating ' conditions involved. (Note; "When conventional masonry paint of the hydra- ting-lype is used, wet down the Pyroscat before painting to insure proper . hydration). ALTERNATES FOR TOWER SKIRTS (VERTICAL) A-2 Attach a layer of 1" x 1" square mesh reinforcing, positioned 1" away from the - skirt, i. e., at the approximate center of the fireproofing thickness specified. a) - Trowel or gun Pyroscat solidly through openings in the square mesh, bringing the scratch coat out approximately 1" thick. Start at the bottom of the skirt and work upward. Leave the surface rough, or scratch it when trowel applied. - `\ b.) Screed strips may be attached temporarily over the square mesh reinforc ing, to accurately gauge the thickness of the second layer. c) When fireproofing is applied to skirts of heated vessels while they are in . operation, heat conducted to the skirt may prematurely dry the initial layer * of Pyroscat. Wet the first coat thoroughly, particularly at the top, before applying the final layer. ' ALTERNATES FOR HORIZONTAL TANKS ` A-2 Bolster bars are preferred for anchorage of the reinforcing mesh. The bolster bar selected would have legs extending from the tank surface approximately one-half of the total thickness of Pyroscat to be applied. Form the bolster bars to fit the tank curvature, then weld or wire in place circumferentially approxi mately 3' on centers. Wire the reinforcing mesh to the bolster bars. C-3 When tanks so fireproofed are to be operated below ambient temperature, suit able vapor-sealing treatment is recommended after the _5yroscat has been cured, dried and flashed.

These ingredients are factory blended to a uniform dry mixture that is ready for application after mixing with water at the job site, i Pyroscat is adapted to application by spraying, casting and trowelling techniques, depending on job conditions. USES: Pyroscat provides a lightweight, fire-retardent protective-treatment' for structural steel columns, beams, tower skirts, L.P gas tanks, and other exposed applications in refineries and chemical plants. Pyroscat sets up to a hard, durable sheath capable of withstanding for hours the 2000F. flame temperatures and Sigh-pressure water streams commonly encoun tered in industrial fires. :* . RECOMMENDED THICKNESSES: Fire-retardent materials are customarily rated in Hours, based on a given thickness used and on the method of application. For example, fire ratings for steel columns represent the number of hours required for'heat from a "standard fire" to penetrate the protective treatment as applied, and to increase the steel column temperature to a critical level (1200F;). The thermal conductivity and-heat capacity of a material are of some impor tance in an ASTM Fire Test. But the ability of the complete treatment to withstand thermal shock without destruction is one of the most significant factors in determining practical fire ratings in industrial installations. The Pyroscat thicknesses recommended below were determined by physical tests on a series of sprayed, cast and trowelled applications. Tests in cluded direct exposure to 100 psi hose pressure, both before and after subjecting the Pyroscat treatment to severe flame conditions. Thickness of Pyroscat 1" 1-3/4" 2" ' Approx. Fire Resistan .e Rating 2 Hours ADVANTAGES OF PYROSCAT Safer While Fighting Fires .... Many concrete aggregates and common bricks used for fireproofing purposes will spall and shatter when they are heated and subjected to a hose stream. Pyroscat remains virtually unaf fected after directfLame exposure and saturation with alOOpsihose stream.

Pjroscat weighs less than 55 lbs. /cu. ft. in place, compared to approximately 150 lbs./cu. ft. for conventional concrete fireproofing. Excess dead weight is eliminated. As. usually sprayed or trowelled in a protective sheath, Pyroscat weighs about 1/10 as much as formed concrete - at equivalent thickness per running foot. *. . . Spray, Cast or Trowel.... Pyroscat is specially formulated to permit installation by spray, trowel and casting techniques, depending on local job conditions. No other fireproofing material is as versatile, from an application standpoint. Em ploys conventional supporting materials and placement. Only the one fireproofing material is required - no need for subsequent finishing layers nor heavy mastic coatings. ' .. Durable and Weather-Resistant.... Pyroscat develops great strength from its selected high-temperature aggregates and hydraulic-setting binders. It with- ' stands continued cycles of saturated freeze-and-thaw weathering tests.
