UNION CARBIDE (a/idria ASBESTOS UNION CARBIDE CORPORATION . METALS DIVISION P.O.BOX 579 NIAGARA FALLS, N.Y. 14302 TEL: 716-278-3376 "Calidria" Asbestos Resin Grade-144 & Resin Grade-244 "Calidria" Asbestos - A chrysotile fiber obtai ned from a unique short-fiber deposi., which is essentially free of hard consolidated rock masses typical of other asbestos ores. A proprietary "wet process" breaks down the fiber bundles, removes rocks and other contaminents and provides 98? liberated. efficient fibrils of uniform quality. RG-144 - A highly-refined grade of "Calidria" Asbestos used as a viscosity control agent in epoxys, vinyl plast iso Is, asphaltic compounds, polysulfide and butyl rubber sealants, silicone and casein adhesives. Unlike other thixotropes, RG-144 can be used effectively with amine hardeners in epoxy systems and has an indefinite shelf life. It costs only about 1/4 as much as pyrogenic silica, and is generally used at addition levels of I - I 1/2?. RG-244 - Very highly refined "Calidria" fiber which has been surface-modified for use as a thickening agent and thixotrope in polyester spray-up and hand lay-up resins, in vinyl sealants, in epoxys, and in a variety of adhesives, coatings and mastics. In many systems RG-244 does not contribute color or opacity - a character istic that makes it particularly attractive in polyester gel coats. It offers ease of dispersion with minimum settling and stable rheological properties. RG-244 costs less and is generally used at lower levels than other thixotropes. Packages of RG-144 and RG-244 are sealed with polyethylene overwraps to ensure moisture protection and are readi y available at many warehousing points.
