"CALIDRIA" ASBESTOS SG-130 AND SG-210 For Tape Joint Compounds n Lowers Costs Two Ways CALIDRIA Asbestos acts as a body ing and secondary chickening agent permitting formulation of lower den sity, more economical cape joint com pounds without the sacrifice of per formance. CALIDRIA Asbestos is produced by a proprietary manufactur ing process chat yields unusually high fiber concent 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 ocher filler materials chac have no specific desirable effects on tape joinc compound properties. 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 gready re duces the tendency for cracks over nail holes, in thick sections at the center of the joint, and along the feathered edges. Enhances Sondabilify CALIDRIA Asbestos contains mainly chrysocile fiber arid 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 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. 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 alsobe able to use slightly more water in your ready-mix and maintain your present vis cosity level. No other changes in your October. 1968 F-J22S8 CALIDRIA. CELLOSlr-E.

CALIDRIA Asbescos SG-130 has the coarser particle size; it finds use for bedding compounds or perhaps spackling compound. The SG-2I0 has the finer parti cle size and is favored for topping com pounds, all-purpose compositions, texture paints, and similar formulas.

TOXICOLOGICAL PROPERTIES It has been known for many years that some persons working in asbescos produc tion were prone to develop a disabling lung disease. Iu time, this condition became known as asbestosis and was related ro exposure to high concentrations of asbes tos dust. With further experience, it was found that men could work with asbestos wichout development of lung disease if dust concentrations were kept below a certain level. It is now generally accepted that a man can work a -10-hour week for a lifetime wichout developing asbestosis if the asbestos dust particle count is kepc 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 "CALIDRIA" ASBESTOS SG-130 AND SG-210 TOXICOLOGICAL PROPERTIES (Confirmed) of asbestosis are believed co have occurred when exposures have been maintained ac 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 che 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 ac 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 syscern are necessary. Pelletizing is sometimes used to improve che 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 to determine that Threshold Limit Values are not being exceeded. Employees should wear respirators where dusting occurs in finishing products such as sanding caped joints. Pte-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 che 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 "CALIDRIA" ASBESTOS SG-130 AND SG-210 For Tope Joint Compounds RELATIONSHIP BETWEEN WATER & OIL ADSORPTION CAPACITY OF SOME ASBESTOS PRODUCTS FOR TAPE JOINT ADHESIVE FORMULATIONS 9 THE DISCOVERY COMPANY Sa/es Offices UNION CARBIDE CORPORATION CHEMICALS AND PLASTICS 270 PARK AVENUE.
