ASTM E866-23

Standard Specification for Corrosion-Inhibiting Adhesive Primer for Aluminum Alloys to Be Adhesively Bonded in Honeycomb Shelter Panels

ABSTRACT
This specification covers corrosion-inhibiting adhesive primers for use on aluminum alloys that are to be adhesively bonded in the fabrication of honeycomb sandwich panels for tactical shelters. When applied to a properly cleaned surface of aluminum alloy, the primer imparts corrosion resistance and forms a surface suitable for structural bonding and coating with shelter paint finishes. The primer shall be a pigmented liquid composed of a modified epoxy resin system, compounded so that it can be spray-applied to produce a continuous coating without the addition of any solvent. Uncured primers shall be tested for solids content, inhibitor content, storage stability, shelf life, color, sprayability, and curing properties. Cured films, on the other hand, shall be tested on adhesion to metal, impact resistance, pencil hardness, water resistance, environmental resistance, corrosion resistance, humidity aging, heat resistance, and low-temperature shock. Finally, bonded specimens shall be tested and conform to normal-, low-, and high-temperature lap shears, humidity-exposure lap shear, salt-spray exposure lap shear, and normal- and low-temperature floating roller peel strengths.
SCOPE
1.1 This specification covers sprayable, pigmented liquid primers for use on aluminum alloys that are to be adhesively bonded in the fabrication of honeycomb sandwich panels for tactical shelters. When applied to a properly cleaned surface of aluminum alloy, the primer imparts corrosion resistance and forms a surface suitable for structural bonding using adhesives complying with Specification E865 and for coating with shelter paint finishes.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
