This specification covers adhesion promoters in the form of a liquid, either in bulk or aerosol form. This product has been typically used to enhance the adhesion of polysulfide sealing compounds or adhesives to AMS-C-27725 integral fuel tank coating, MIL-PRF-23377 epoxy primer, MIL-PRF-85582 waterborne primer, and bare titanium alloy substrates, but usage is not limited to such applications. Care should be exercised around plastic substrates (e.g. polycarbonates, acrylics) as the formulary solvents may tend to craze these surfaces. AMS3100 Class 2 may contain halogenated solvents that could cause stress-corrosion cracking when used on titanium alloys which will be subjected to temperatures above 450 °F (232 °C) or on high strength steels. Users of this specification should be attentive to reference the appropriate class of promoter for their specific applications.

This SAE Aerospace Recommended Practice (ARP) provides methods and guidelines for isolating dissimilar repair patch materials from carbon composite structure during a repair operation. These procedures are applicable to any repair procedure for carbon fiber reinforced plastic parts in which the repair patch is a metallic alloy that can form a galvanic cell with carbon in the presence of moisture or other electrolytes. The principal patch materials addressed are aluminum, titanium, and stainless steel. The procedures are primarily concerned with bolted repairs that introduce the most severe, potential corrosion problem but bonded repairs are also considered. The procedures are also applicable to repairs involving reinstallation of metallic inserts into a carbon fiber reinforced plastic part. Fiberglass and aramid fiber reinforced plastics do not have galvanic reactions with other materials, and the procedures outlined herein are, therefore, not essential with these materials. The sealing procedures covered herein are still recommended, however, as a means of preventing moisture entry.

Standard reference fluids, or test fluids, have long been used to evaluate the effects of hydrocarbon fuels on various materials, such as integral fuel tank sealants. Standard fluids are required because hydrocarbon fuels, such as JP-4, vary widely in composition depending on crude source, refining techniques, and other factors. To ensure reliable and reproducible results when determining the fuel resistance of materials, reference fluids of known composition, using worst case fuel compositions, are used. The current Jet Reference Fluid (JRF) called out in military sealant specifications was developed in the mid-1950s specifically as a JP-4 type test fluid formulation to be used for the accelerated laboratory testing of integral fuel tank sealants. In August 1978, chalking of the polysulfide sealant in integral fuel tanks of some new aircraft at Edwards Air Force Base in California was discovered after only 1 year of service. Although chalking of polysulfide sealants had been observed occasionally in the past, the rate of chalking was unprecedented.
