A CURING AGENT (FOR EXAMPLE, AN AMINE) FOR AN EPOXY RESIN IN ENCAPSULATED IN A READILY RUPTURABLE THERMOPLASTIC MATERIAL (FOR EXAMPLE, WAX), AND ADMIXED WITH AN EPOXY RESIN UNDER A FIRST PRESSURE WHICH IS IN EXCESS OF ATMOSPHERIC AND SUFFICIENT TO PRECLUDE RUPTURE OF SAID READILY RUPTURABLE THERMOPLASTIC MATERIAL. THE RESULTING ADMIXTURE IS THEREAFTER EXPOSED TO A SECOND PRESSURE LESS THAN THE FIRST PRESSURE, WHEREBY SAID READILY RUPTURABLE THERMOPLASTIC MATERIAL RUPTURED, THEREBY CAUSING THE MIXTURE OF CURING AGENT AND EPOXY RESIN TO COME INTO REACTIVE CONTACT. |
