AV 980 is used to remove corrosion inhibiting compounds (CIC), waxes and greases from airframes and aircraft components. It has a neutral pH, can be removed with water rinsing and is biodegradable.
Range Of Use
AV 980 is used for cleaning and degreasing internal and external aircraft structures and components. It can be used to remove CIC overspray in the manufacture of aircraft and for removing old or damaged CIC during aircraft maintenance and repair.
AV 980 will not damage or affect commonly used materials within the aircraft structure, however, acrylic materials such as acrylic glazing should be masked to prevent direct contact.
AV 980 is applied by brush, dip or spray as appropriate to the structures and components being treated. A generous coating is recommended, using typical film thicknesses of 30 to 150 microns.
AV 980 is thixotropic and can be applied to vertical and overhead surfaces without dripping.
AV 980 can be spray applied using the ACS System (airmix application), or the AAS System (airless application).
Contact times of 10 minutes and up to 2 hours are recommended depending on the type, age and condition of the CIC, wax or grease being removed.
The optimum contact time for removal can be determined by applying AV 980 and then checking periodically (perhaps every 10 minutes)
whether the softening process is sufficiently advanced to allow clean, easy and effective removal. If the CIC, wax or grease is particularly difficult to remove, and one application of AV 980 is not totally effective, then another coating can be applied and the removal process repeated until the CIC, wax or grease has been completely removed.
AV 980 and the softened CIC, wax or grease can be removed using high pressure water rinsing (cold water at 50 to 140 bar pressure).
Operating instructions and recommendations for using spray equipment are given in the Technical Manual “Aircraft Corrosion Protection and Control“ available from the local Chemetall Sales Office
