Adhesion Promoter For Polysulfide Sealing Compounds
|Publication Date:||1 November 2013|
This specification covers adhesion promoters in liquid form for use with aerospace sealing compounds.
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.
Safety - Hazardous Materials
Shall be in accordance with AS5502 (1.1).
Adhesion promoters shall be classified by formulary ingredient(s) and volatile organic compound (VOC) content as follows (See 8.4):
Class 1 - Nonhalogenated organic solvent(s)
Class 2 - Nonrestricted organic solvent(s)
Class 3 - Water-based composition
Type 1 - Standard VOC content (greater than 250 g/l)
Type 2 - Low VOC content (250 g/l or less)
