49836676, Jan 8, 1991

Filed:

Jun 2, 1989

Appl. No.:

7/360616

Inventors:

Samuel L. Bagdasarian - Kissimmee FL

Assignee:

Raytheon Company - Lexington MA

International Classification:

C08L 7504

US Classification:

524703

Abstract:

A sprayable ablative coating formulation comprises a combination of a polymeric resin, a curing agent, cork flour and a vehicle such as toluene. The mixture is sprayable using conventional spray equipment. The surface to be coated is first sprayed with a primer to improve adhesion, and the mixture is than sprayed over the primed surface until a desired thickness is formed. Once cured, the coating has a uniform fine texture and thickness, providing thermal insulation for the coated surface. Pigments may be added to the formulation to acheive specified coloration of the coating.

Abstract:

A composition of ferrite and epoxy having the form of a film which can be cut, pressed onto word straps, and heat-cured to form an encapsulating keeper on a plated wire memory. The film comprises ferrite powder in a mixture of epoxy resins, typically Epon 1009 and Epon 828, pulverized dicyandiamide and butadiene/acrylonitrile rubber. The mixture is sprayed onto a sheet of halogenated polyolefin and air dried for 8-12 hours at between 160. degree. F. and 180. degree. F. The resulting flexible film is die cut to fit over word straps and further processed by applying 50-75 psi at 325. degree. F. for one hour.
