Claim of US Patent No. 10,336,047

1. A method of preventing corrosion of the mating surfaces of components, said method comprising:(i) impregnating a polyester based carrier with at least one anaerobic acrylic adhesive to form an impregnated carrier;
(ii) spraying at least one pressure sensitive acrylic adhesive on one surface of said impregnated carrier to form an impregnated carrier having a pressure sensitive acrylic adhesive layer;
(iii) protecting said pressure sensitive acrylic adhesive layer using a protective silicon release liner to configure a pasting surface on said impregnated carrier;
(iv) pasting said pasting surface after detaching said silicon release liner therefrom on a first component, wherein said pasting surface is in contact with said first component;
(v) abutting a second component to said first component such that said impregnated carrier is sandwiched therebetween; and
(vi) applying force on said abutted first and second components such that said anaerobic acrylic adhesive oozes out from said impregnated carrier and coats mating surfaces of said abutted first and second components in the absence of oxygen to commence and complete curing of said anaerobic acrylic adhesive on mating surfaces of said first and said second components.
