REFRACTORY & INSULATION- CORPORATION UTILITY THERMAL FINISH CEMENT PLAINTIFF'S * EXHIBIT Utility Thermal Finish Cement is composed of high quality mineral fiber, hydraulic binders, and other suitable materials. Utility combines 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 Insulating Finish Cement develops a smooth, durable, protective finish within a few hours after application and without the presence of heat. Subsequent drying produces no excessive surface cracking or shrinkage in thickness, and occasional I 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 lating 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 at600F.mean temperature. This excellent insu lating value as compared to other finish cements is a very desirable advantage when figuring job and operating costs. May. 1964 PHYSICAL PROPERTIES /Service Temperature 1200F.
