un- r B Effective, low-cost thickening agent and thixotrope for epoxy resin systems imparts excellent viscosity control to resin systems (coatings, adhesives, sealants, caulks, mastics) KMX 02079 8 a/idrktA Resin-Grade 144 Isbestos ... a highly purified fiber product that is an effective, low-cost thickening agent and thixotrope for epoxy resin systems. By means of a special refining technique developed by UNION CARBIDE, CALIDRIA Resin-Grade 144 Asbestos is made completely grit-free and non-abrasive--this latter char acteristic makes it especially valuable in spray application. Other desirable features of CALIDRIA Resin-Grade 144 Asbestos include: . Disperses easily in liquid resin or hardener with a "Cowles" Dissolver or similar mixers Overmixing will not destroy the thixotropy of the resin-asbestos mixture Epoxy systems containing CALIDRIA Resin-Grade 144 Asbestos have excellent aging characteristics Reduced dust Unlike other thixotropes, it is effective with amine hardeners CALIDRIA Resin-Grade 144 Asbestos is substantially lower in cost than commonly used refined silicas or modified clays . No amine salts are necessary for viscosity build-up or thixotropic stabili zation (with the exception of the low-viscosity, cycloaliphatic epoxides) Typical physical properties Specific Gravity 2.45 Moisture Content, % by wt..................................... 2.0, maximum Surface Area, sq. meters per gram................................ 60, appr.

It compares relative differ ences in viscosity of BAKELITE Epoxy Resin ERL-2774 solu tions containing equivalent concentrations of CALIDRIA R-G 144 Asbestos, micro-crystalline silicate, and pyrogenic silica. Figure 2 illustrates the ability of CALIDRIA R-G 144 Asbestos to control viscosity in two different solvent-epoxy systems used in many epoxy coatings and paints. Figure 2 VISCOSITY CHARACTERISTICS OF CAUDRIA R-G 144 IN BAKELITE EPOXY SOLUTIONS Resin and amine hardener evaluation METHOD OF INCORPORATING THE THIXOTROPE: In preparing the test samples used in determining data for Tables 1, 2 and 3, the thixotrope--CALIDRIA Resin-Grade 144 Asbestos--was added to the liquid resin or hardener at 25C. and dispersed in a "Cowles" Dissolver at 2400 rpm. for 5 minutes. VISCOSITY MEASUREMENTS: Viscosities of the prepared test samples were measured on a Brookfield Model RVF Viscometer at 2 and 20 rpm. Table 1 shows performance data of bisphenol based resins, BAKELITE ERL-2774 and ERL-2795, with up to 4 PHR. of CALIDRIA Resin-Grade 144 Asbestos. Vertical draw down was excellent, and even higher asbes tos loading should result in even higher verti cal draw-down.

Table 2 presents data that show the effec tiveness of CALIDRIA Resin-Grade 144 As bestos as a thickener of several types of BAKELITE Amine Hardeners.

Higher loadings on the amine should result in much higher vertical drawdown. BAKELITE ERL-2774/ZZL-0820 A 4-per cent loading of CALIDRIA ResinGrade 144 Asbestos resulted in a 40-mil thickness that did not sag within 40 minutes at 80C. The system was gelled at that time. BAKELITE ERL-2774/ZZL-0854 With a 4-percent loading of CALIDRIA ResinGrade 144 Asbestos, it was possible to hold a 40-mil thickness at 80C. until gelled (65 minutes). CALIDRIA Resin-Grade 144 THE DISCOVERY COMPANY UNION CARBIDE CORPORATION ASBESTOS 270 PARK AVENUE, NEW YORK, N.
