"CALIDRIA" ASBESTOS SG-130 AND SS-210 For Tape Joint Compounds Lowers Costs Two Ways CALIDRIA Asbescos acts as a body ing and secondary chickening agenc permitting formulation of lower den sity, more economical tape joinc com pounds wichouc the sacrifice of per formance. CALIDRIA Asbestos is produced by a proprietary manufactur ing process that yields unusually high fiber concenc and more complete fiber liberation from the natural bundles. As a result, CALIDRIA Asbescos goes up to twice as far, pound for pound, as commercial grades of as bescos containing large amounts of ocher filler materials chat have no specific desirable effects on tape joinc compound properties. Reduces Cracking The fibers of CALIDRIA Asbestos behave as an accive lyophobic colloid in aqueous dispersion; by this mecha nism CALIDRIA Asbescos increases cape joinc compound liquid cohesive strength during drying. Increased liquid cohesive screngch greatly re duces the tendency for cracks over nail holes, in chick sections at the center of the joint, and along the feathered edges. Enhances Sandability CALIDRIA Asbescos contains mainly chrysocile fiber afid is essentially free from abrasive concaminancs, such as magnetite and serpentine rock dust. This composition results in a low density produce, free from con taminants thac 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 bacch to batch and improve the uniformity of tape joint compounds using CALIDRIA Asbescos. Suggestions for Use of CALIDRIA Asbestos CALIDRIA Asbescos can be readily used in your present tape joint compound formulation. Add approximately one-half the proportion of asbescos 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 Ociober, 1968 F-422S8 CALIDRIA. CELLOSlr_E.

CALIDRIA Asbestos SG-130 has the coarser particle size; it finds use for bedding compounds or perhaps spackling compound. The SG-210 has the finer parti cle size and is favored for topping com pounds, all-purpose compositions, texture paints, and similar formulas.

TOXICOLOGICAL PROPERTIES 1c 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 JO-hour week for a lifetime without developing asbestosis if the asbestos dust particle counc 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 "CALIDRIA" ASBESTOS S6-130 AND SG-210 TOXICOLOGICAL PROPERTIES (Continued) of asbescosis are believed co have occurred when exposures have been maintained ac or below this level, despice large-scale utilization (now approaching one million tons per year in che U.S.A.). This concen tration of dust is generally not visible in che average work area unless a beam of light causing a Tyndall effect is presenc. Usually the dust concentration must be from 8-10 million particles per cubic fooc before ics presence is visible in average lighcing conditions. Several years ago, it was reported that there was an increase in che incidence of cancerous tumors, especially of the lung, associated with asbescosis. Recendy chere have been reports of some cancers occurring in individuals exposed to asbescos dust, but who have not developed clinical as bescosis. It is believed by most authorities that these cases have been associated with exposures significantly exceeding the Threshold Limic Value. A major manufac turer of asbescos products who also mines asbescos 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 asbescos dust exposure is therefore necessary. The concrol 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 che system are necessary. Pelletizing is sometimes used co 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 che protection of the employee. A pro gram of environmental monicoring in manu facturing operations is highly desirable to determine chat Threshold Limic Values are noc 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 chat 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 ocher 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 5 THE DISCOVERY COMPANY Safes Offices UNION CARBIDE CORPORATION CHEMICALS AND PLASTICS 270 PARK AVENUE, NEW YORK.
