Adhesion Promoter For Polysulfide Sealing Compounds
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.
AMS3100D primarily clarifies the VOC content and the composition control requirements, and corrects an error in Table 4.
