Abstract
An improved patch and method of repair of the integrity and/or surface imperfections of a structure which is defective because of accidental damage or flaws during the course of manufacture or subsequent use and handling. The invention relates to the use of a fibrous cloth which is impregnated by a fast curing acrylic-based adhesive composition which is utilized with an activator/accelerator that can be applied to the margins of the faulty workpiece and thence to the overall impregnated cloth to quickly cure it at ambient temperature. The improved material provides good adhesion to a wide variety of materials including unprepared metals, painted metals, plastics and moist or oil contaminated surfaces and displays a high impact strength heretofore not found in such materials.
