...a chemically modifiedhighly refined fiber with a mineral coating that gives: HIGHER VISCOSITY AT LOW LOADINGS-- "Calidria" asbestos RG-244 builds more vis cosity at a given concentration than pyrogenic silica or other thickeners. Part of this viscosity increase comes from hydrogen bonding be tween the mineral coating and the resin system --the same way that pyrogenic silica builds viscosity. What makes RG-244 more efficient is that the fibers enhance flow resistance. On a Ib.-for-lb. basis, RG-244 builds over twice as much viscosity as pyrogenic silica. BETTER FLOW AT HIGH SHEAR RATES"Calidria" RG-244 also improves flow at high shear rates because of its inherent thixotropic characteristics. This property is especially de sirable in spray-up applications where less resistance to flow is desired during pumping and spraying. SAVINGS FROM BETTER PERFORMANCEBy increasing viscosity and thixotropy more efficiently than other materials, "Calidria" asbestos RG-244 allows users to obtain their desired properties with less mineral additive. This reduction lowers costs and reduces any detrimental effect of thickeners on other resin properties. LOW COSTS TOO--"Calidria" asbestos RG244 costs less per lb. than similar thickeners. Thus, users save two ways--on unit cost and cost performance. FAST WETTING. EASY DISPERSION--Con ventional mixing equipment can be used to disperse "Calidria" RG-244 quickly and easily. In fact, this unique product wets out and dis perses considerably faster than most other thixotropes. BETTER SHELF LIFE. LESS SETTLING -Sys tems containing "Calidria" asbestos RG-244 can be stored for long periods without any significant change in viscosity or thixotropy. Settling during storage is minimized, and sys tems containing RG-244 can be remixed easily. In all these respects, RG-244 surpasses most other thickeners. NO COLOR OR OP/CilY "Calidria" asbes tos RG-244 is a highly refined fiber with a clear mineral coating that does not add color to most systems. At the same time, RG-244 has a refractive index that matches many systems, so that it does not add opacity. These features make RG-244 especially well suited for use in clear polyester gel coats. REDUCED DUSTING "Calidria" RG-244 is a fibrous material containing a minimum of dust. It therefore reduces dusting during materials handling and additions to resin systems.

"Calidria" asbestos RG-244 is stocked at Union Carbide's shipping locations throughout the United States and is available from several distributors. UCC 001742 Why is "Calidria" asbestos different? "Calidria" products are made from highpurity, short-fiber chrysotiie asbestos obtained from a unique deposit about 160 miles south of San Francisco, California. Unlike conven tional 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 fiber compared to conventional deposits which contain from 6 to 10% asbestos. Special hydraulic beneficiation techniques developed 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% liber ated from fiber bundles. RG-244 is made by additional refining to achieve over 99% purity. The fibers are then chemically coated by a patented process to form this unique, highly efficient thickener and thixotrope. CANADIAN ASBESTOS--AS-MINED--Individual fiber bundles are straight and tightly bonded, surrounded by consolidated rock masses. In this form, the fibers defy separation 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 up to 0% asbestos, considerably more than the Canadian ore. "CALIDRIA" ASBESTOS--IF DRY-PROCESSED-Even the most exacting dry processes do not completely break down the fiber bundles into individually liberated fibers. Union Carbide technology developed a special wet proc ess to liberate the fibers. "CALIDRIA" ASBESTOS--UNIQUELY WET-PROCESSED -- Union Carbide's process separates 98% of the fibers from the fiber bundles. RG-244 fibers are over 99% pure asbestos and chemically coated to provide an efficient thickener and thixotrope. UCC 001743 Typical Performance DatajGeneral Purpose UNPROMOTED Polyester Resins HIGHER VISCOSITY AT GIVEN CONCENTRATION On a Ib.-for-lb. basis, "Calidria" asbestos RG-244 builds substantially more viscosity in these 2 polyester systems than pyrogenic silica. RG-244 builds twice as much viscosity at a 1 % concentration and 4 times as much viscosity at 3% concen tration. Thus, users can use less RG-244 to obtain their de sired viscosity. HIGHER VISCOSITY AT LOW SHEAR RATES BETTER FLOW AT HIGH SHEAR RATES 2% "Calidria" asbestos RG244 gives better thixotropic properties than 4% pyrogenic silica in this unpromoted poly ester resin containing about 50% styrene. The RG-244 sys tem has better flow at high shear rates, allowing easier pumping and spray-up. As the shear rate is reduced, the RG244 resin has better viscosity and sag resistance. UCC 001744 SAVINGS USING "CALIDRIA" ASBESTOS RG-244-UNPROMOTED Polyester Resins The better performance and lower cost of "Calidria" asbes tos RG-244 allow substantial savings. In the typical unpro moted polyester resin system shown at the right, "Calidria" RG-244 builds a given viscosity for about one-half the cost of pyrogenic silica. Typical Performance Data/General Purpose PROMOTED Polyester Resins IMPROVES BOTH VISCOSITY AND THIXOTROPY "Calidria" asbestos RG-244 also effectively improves the viscosity and thixotropy of pro moted polyester resins, in many cases, the improved vis cosity and thixotropy provided by RG-244 will be sufficient to meet user needs. Should higher values be required, a small ad dition of ethylene glycol or a similar additivewill improve the viscosity, thixotropy, and sta bility of the RG-244 dispersion. At the right is an example of these improvements in a typ ical polyester resin containing a cobalt-type accelerator. UCC 001745 Typical Performance Data^Heat-Curabie vinyl plastisol Sealants "Calidria" asbestos RG-244 improves the vis cosity of heat-curable vinyl plastisols without reducing their inherently good adhesion prop erties, In fact, RG-244 provides excellent anti sag properties at both low (275 to 375 deg. F.) and high (above 350 deg. F.) fusion tempera tures. An example of how RG-244 improves the viscosity of a high-fusion temperature structural sealant without detracting from ad hesion is shown below: FORMULATION FOR HIGH-FUSION TFMFERATURE STRUCTURAL SEALANT INGREDIENT BAKELiTE QYOH-2 Resin FLEXOL Plasticizer 10-10 FLEXOL Plasticizer 10A EX-1 Extender Plasticizer Barium-Cadmium Stabilizer UNION CARBIDE Silane Y-5162 Adhesion Promoter Calcium Carbonate CALIDRIA Asbestos RG-244 PARTS BY WEIGHT 100 60 40 10 2 0.25 130 5 TEST DATA Butt tensile adhesion to cold-rolled steel after 45 minutes cure at 350 F.

Pressures above 300 psi tend to reduce viscosities. In general, "Calidria" asbestos RG-244 requires less en ergy for adequate dispersion than comparable concentrations of pyrogenic silica. TOW!. FS" DISSOLVER A "Cowies" dissolver can disperse "Calidria" asbestos RG-244 in 5 to 10 minutes at 3500 rpm, using a 3-in. impeller in a 3-quart con tainer. Under these conditions a 1% loading can be mixed for 1 hour while a 2% loading can be stirred for 30 minutes without degrad ing. Large volumes of RG-244 can be dis persed easily by scaling up the equipment.
