ETCHING MATERIALS FOR
Our innovative high viscosity paste fills an unmet need
The Navy needed a safer and more efficient alternative to the hazardous process used in traditional non-destructive inspection (NDI) processes to test aircraft components for cracks and corrosion. ANI’s solution, which has been successfully tested on Naval aircraft materials, has the high viscosity of toothpaste, comes in single-use packets, has a long shelf life, and gets the job done more effectively and safely.

Our three-packet kit: safe, convenient, effective
The traditional method involves dipping aluminum alloys in large baths of corrosive etchant materials which are difficult to contain, may damage other components, and could expose users to chemical burn. Our high-viscosity materials are contained in a three-packet kit (etchant, neutralizer and de-smut) for single-use application, and can be used as-is with no mixing.
More revealing than traditional processes
Far from compromising performance, the increased viscosity ANI solution has demonstrated improved etch-rate. It achieves 0.5 micros/min etch rate at <30° C and uncovers cracks more visibly than with traditional methods. An added advantage is the shelf-life of <12 months. Packets maintain their integrity under weights of 25lb.

A Navy-tested product with broad applications
Penetrant NDI is important for early detection of corrosion and structural damage before component failure. The ANI solution has been successfully tested for use on Navy aircraft, but similar NDI needs are found on commercial aircraft, oil and gas exploration, refineries and pipeline transportation, ocean cargo vessels, railways, and aluminum industries in general.
