Resinous composition for determining surface strain concentrations in rigid articles
Abstract
Abstract A LIQUID RESINOUS COMPOSITION COMPRISING A WATER RESISTANT RESIN OF SUITABLE MELTING POINT AND A PLASTICIZER DISSOLVED IN A VOLATILE SOLVENT, CAPABLE OF FORMING, WHEN DRIED ON THE SURFACE OF A RIDGID ARTICLE, A THIN BRITTLE FILM THAT IS RELATIVELY INSENSITIVE TO HUMIDITY AND THAT, WITHIN A TEMPERATURE RANGE OF 0* TO 130*F., IS HIGHLY SENSITIVE TO STRAINS OF 100 MII AND ABOVE, AND THEREFORE USEFUL FOR THE DETERMINATION OF STRAIN CONCENTRATIONS. THE COMPOSITION CAN BE APPLIED TO THE SURFACE AS A LIQUID SPRAY OR AS AN AEROSOL TO BUILD UP A BRITTLE FILM OF BETWEEN 0.004 AND 0.009 INCH IN THICKNESS WITH A MYRIAD OF MINUTE BUBBLES THEREIN THAT FACLITATE THE ACCURATE DETERMINATION OF SURFACE STAINS.
