CALIDRIA Asbestos is low density product, free from con produced by a proprietary manufactur taminants that interfere with sanding ing process that yields unusually high fiber content and more complete fiber Improves Uniformity 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 Narrow and well-controlled particle size distribution, low alkalinity and high brightness 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 Cracking The fibers of CALIDRIA Asbestos behave as an active hophobic 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 ac the Suggestions for Use of CALIDRIA Asbestos - CALIDRIA Asbestos can be readily used in your present tape joint compound formulation, Add approximately onc-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 1 "CAUDRIA" ASB ESTO S SG-130 AND SG-210 For Tape Joint Compounds < Suggestions for Use of C A U D R IA Asbestos (Continued) formulation or manufacturing procedure are required CAUDRIA Asbestos SG-130 has the coarser particle size, it finds use for bedding compoutds or perhaps spackling compound.

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 1/ dust concentrations were kept below a certain level. It is now generally accepted that a man can work a dO-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 3 "C A L ID R IA " A S B E S T O S S S -1 3 0 A N D S G -2 1 0 f T O X IC O L O G IC A L P R O P E R T IE S (Continued) of asbestosis are belteved 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 m 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 \anecy of dusty operations. They include closed flow systems, wet processes where possi ble, and adequate exhaust ventilation where openings in the system are necessary. Pellecizing is sometimes used to improve the handling characteristics of otherwise dusty materials. Where 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 ro determine that Threshold Limit Values are not being exceeded Employees should wear respirators where dusting occurs m 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 Lima 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 "CALIDRIA" A S B E S TO S S G -130 AND SG -210 For Tope Joint Compounds ** RELATIONSHIP BETWEEN WATER & OIL ADSORPTION CAPACITY OF SOME ASBESTOS PRODUCTS FOR TAPE JOINT ADHESIVE FORMULATIONS s < TH E DISCOVERY COM PANY Sales Offices UNION CARBIDE CORPORATION CHEMICALS AND PLASTICS 2 70PARKAVENUE, NRW YORK N.Y. 10017 U n ite d S ta te s ' F ,, ^ n - t - Affiliates - ATLANTA.
