To make a component, the cavity of a female mold is sprayed with a polyester gel coat to a thickness of .025". After the gel coat sets, it is sprayed with the base structure of glass fiber and polyester resin to a nominal thickness of 3/16". The completed component is then removed from the mold. The gel coat was originally formulated from a polyester resin, a filler and a viscosity control agent (thixotrope) of colloidal silica. Substitution of a resin-grade asbestos for the colloidal silica as the thixotrope in the gel coat has resulted in significant cost savings for the manufacturer. The asbestos costs about half as much as silica, has higher yields, gives better batch consistency using less thixotrope and is more readily wetted by the resin without fluffing up. making spraying quicker and easier. . ' The asbestos used is Union Carbide Corporation's CAL- I P R I A Asbestos, Resin-Grade 244. Material cost savings in the range of $10.00 per 800-pound batch are being realized, stability problems are eliminated and viscosity is maintained during lengthy storage periods. ' G EN U IN E PIT SEA L is an emergency gasketing ma terial that will become semi-plastic with fil natural heat gen erated by 'the metal surfaces lietween which it is Used. It is for use where a flange or a joint is badly pitted, scored or distorted and when plant down-time is impracticable due to cost factors or loss of production. The material is composed of long-strand asliestos fillers which ar interwovn with white alloy wire containing a special imported graphite. It will take pressures up to 350 psi and temperatures to 450F and is available in sheet sizes 40" x 40" and 40" x 80" with Vib" and Vie" thicknesses. Free samples of the gasketing material are available from the manufacturer, Industrial Hermetic Materials, Inc., Miami, Florida. ; Page 30 ASBESTOS -- September 1969 PATENTS A b stracts of l \ S.
