CALIDRIA ASBESTOS SG-210 ...an economical, highly efficient product to strengthen and control viscosity of dry and ready-mix ...TAPE-JOINT COMPOUNDS Wa >*<*'^3.-tit'/' PLAINTIFF'S EXHIBIT GP-703 /H-/6 SGP 0021222 SG-210 for TAPE-JOINT COMPOUNDS WATER AND OIL ABSORPTION CAPACITY OF DIFFERENT ASBESTOS FROOUCT3 The high-purity, finely ground fibers of "Caiidria" asbestos SG-210 offer many advantages compared to other types of asbestos including: MORE EFFICIENT STRENGTHENING "Caiidria'' asbestos SG-210 fibers are ground to a fine size, with over 85% of the fibers less than 325 mesh. The product therefore has a large surface area and more active sites to interact with the inert fillers in the compound. Formulators using "Caiidria" asbestos therefore need less material to give dimensional strength to the finished joint. MORE EFFICIENT VISCOSrTY CONTROL The fibers of "Caiidria" asbestos SG-210 can absorb vast amounts of water -- generally about 400 times their weight. As shown by the graph above, this unique asbestos absorbs from 70 to 125% more water and oil than other types of asbestos. Thus, less "CaiidHa" asbestos is needed to reach a given viscosity. 40% SMALLER ADDITIONS This reduction can be made by most users switching to "Caiidria" asbestos SG-210 from other types of asbestos. Such a reduction allows substantial savings in the amount of asbestos to be handled and stored. To make up for the weight difference, extra lime stone should be added to the system. 0 S 10 IS 20 28 30 35 40 WATER RETENTION InM. HjO par 20*. ubmttal LESS CRACKING The smaller addition needed with "Caiidria" asbestos SG-210 reduces shrinkage problems that often occur with large asbestos additions. SG-210 users have reported that cracking over nailholes and along feathered edges has been minimized. SMOOTHER. WHITER COMPOUNDS The tiny particles of "Caiidria" asbestos SG-210 give very smooth compounds when spread and dried. The absence of rock dust and abrasive fillers in this asbestos also contributes to the smoothness. There are no impurities that can discolor the system, so that a whiter compound can also be obtained. CONVINCE YOURSELF To test the effectiveness of "Caiidria" asbestos SG-210, make up a small batch of your present formulation. Add 60% of your normal asbestos addition using "Caiidria" asbestos SG-210. Then make up for the difference in weight using limestone. Overall water demand should be about the same but sometimes varies according to the ingredients in the formulation. Withhold about 10% of the water for final viscosity adjustment at the end of mixing. Then test the properties of the formulation made with SG-210 ... and compare. SGP 0021223 Why is "Calidria" asbestos different? "Calidria" products are made from high-purity, short-fiber chrysotile asbestos obtained from a unique deposit about 160 miles south of San Francisco, California. Unlike conventional deposits that extend through the host rock, this deposit is essentially free of hard, consolidated rock masses. Further, the ore assays up to 60% asbestos compared to conventional deposits which contain from 6 to 10% asbestos. Special hydraulic beneficiation techniques develop ed by Union Carbide efficiently break down the fiber bundles and remove the rock and impurities from the asbestos fiber. As a result, all "Calidria" products are over 95% pure asbestos whose fibers are 98% liberated from fiber bundles. SG-210 is finely ground for use in tape-joint compounds. CANADIAN ASBESTOS - AS-MINED - Individual fiber bundles are straight and tightly bonded, surrounded by consolidated rock masses. In this form, the fibers defy seoaration from each other and from the host rock. "CALIDRIA" ASBESTOS - AS-MINED - Here the fibers are randomly oriented and essentially free of hard rock masses. Further, the ore assays uo to 60% asbestos, consider ably more than the Canadian ore. "CALIDRIA" ASBESTOS - IF DRY-PROCESSED - Even the most exacting dry processes do not comoletely break down the fiber bundles into individually liberated fibers. Union Carbide technology develooed a special wet process to liberate the fibers. "CALIDRIA" ASBESTOS - UNIQUELY WET-PROCESSED - Union Carbide s orocess separates 98% of the fibers from the fiber bundles. The fibers contain virtually no rock dust, abrasive fillers, or impurities that can mar tape-ioint compounds. SGP Use "Calidria" Asbestos T-135 in Acoustical and Texturing Compounds Containing high-purity asbestos and TiO^, "Calidria" asbestos T-135 is a low-cost pigment with secondary thickening action. The titanium dioxide particles are uniformly dispersed along the asbestos fibers and are firmly fixed to the fiber surface by electrostatic attraction. These dispersed Ti02 particles give maxi mum optical efficiency and allow T-135 to replace TiO} on a pound-for-pound basis. The effective thickening ability of the high-purity asbestos fibers also allows removal of asbestos and partial removal of other thickeners. "Calidria" asbestos T-135 therefore provides savings in many spray-ceiling acoustic and wall-texturing compounds. UNION CARBIDE CORPORATION MINING AND METALS DIVISION 270 PARK AVENUE. NEW YORK, N.

CALIDRIA Asbestos is produced by a proprietary manufactur ing process that yields unusually high fiber content and more complete fiber liberation from the natural bundles. As a result, CALIDRIA Asbestos goes up to twice as far, pound for pound, as commercial grades of as bestos containing large amounts of other filler materials that have no specific desirable effects on tape joint compound properties. Enhances Sandability CALIDRIA Asbestos contains mainly chrysotile fiber and is essentially free from abrasive contaminants, such as magnetite and serpentine rock dust. This composition results in a low density product, free from con taminants that interfere with sanding. Improves Uniformity Narrow and well-controlled particle size distribution, low alkalinity and high b rightness are characteristic of CALIDRIA Asbestos. These proper ties are consistent from batch to batch and improve the uniformity of tape joint compounds using CALIDRIA Asbestos. Reduces Crocking The fibers of CALIDRIA Asbestos behave as an active lyophobic colloid in aqueous dispersion; by this mecha nism CALIDRIA Asbestos increases tape joint compound liquid cohesive strength during drying. Increased liquid cohesive strength greatly re duces the tendency for cracks over nail holes, in thick sections at the center of the joint, and along the feathered edges. Suggestions for Use of CALIDRIA Asbestos CALIDRIA Asbestos can be readily used in your present tape joint compound formulation. Add approximately one-half the proportion of asbestos you now use. Increase the proportion of calcium carbon ate or other inert filler to make up for the lower quantity of asbestos. You may also be able to use slightly more water in your ready-mix and maintain your present vis cosity level.

TOXICOLOGICAL PROPERTIES It has been known for many years that some persons working in asbestos produc tion were prone to develop a disabling lung disease. In time, this condition became known as asbestosis and was related to exposure to high concentrations of asbes tos dust. With further experience, it was found that men could work with asbestos without development of lung disease if dust concentrations were kept below a certain level. It is now generally accepted that a man can work a 40-hour week for a lifetime without developing asbestosis if the asbestos dust particle count is kept at or below 5 million particles per cubic foot of air. This dust concentration of 5 million particles per cubic foot of air is the Thresh old Limit Value for asbestos, and no cases SGP 0021230 3 "CALIDRIA" ASBESTOS SG-130 AND SG-21Q TOXICOLOGICAL PROPERTIES (Continued) of asbestosis are believed to have occurred when exposures have been maintained at or below this level, despite large-scale utilization (now approaching one million tons per year in the U.S.A.). This concen tration of dust is generally not visible in the average work area unless a beam of light causing a Tyndall effect is present. Usually the dust concentration must be from 8-10 million particles per cubic foot before its presence is visible in average lighting conditions. Several years ago, it was reported that there was an increase in the incidence of cancerous tumors, especially of the lung, associated with asbestosis. Recently there have been reports of some cancers occurring in individuals exposed to asbestos dust, but who have not developed clinical as bestosis. It is believed by most authorities that these cases have been associated with exposures significantly exceeding the Threshold Limit Value. A major manufac turer of asbestos products who also mines asbestos has not been able to show an in crease in cancerous growths in men work ing where dust concentrations were main tained at the Threshold Limit Value. Control of asbestos dust exposure is therefore necessary. The control methods are the standard ones applicable to a variety of dusty operations. They include closed flow systems, wet processes where possi ble, and adequate exhaust ventilation where openings in the system are necessary. Pelletizing is sometimes used to improve the handling characteristics of otherwise dusty materials. There satisfactory con tainment to stay within the Threshold Limit Value is impractical or impossible, effi cient and reliable respirators are available for the protection of the employee. A pro gram of environmental monitoring in manu facturing operations is highly desirable to determine that Threshold Limit Values are not being exceeded. Employees should wear respirators where dusting occurs in finishing products such as sanding taped joints. Pre-employment and periodic physical examinations of workers are desirable. These should include chest X-rays to in sure that the worker has no chest con dition prior to work with asbestos and to determine that no lung changes are result ing from work with asbestos. In conclusion, while asbestos dust in excess of the Threshold Limit Value is potentially harmful, as are many other dusts encountered in industry, it is as readily controlled as other such dusts and it can be used safely with appropriate precautions. 4 SGP 0021231 `CALIDRIA" ASBESTOS SG-130 AND SG-210 For Top Joint Compound* SG-210 \J SG-130 od> \ Q.
