METHODS OF APPLYING BOND PRIMER COMPOSITIONS FOR BONDED AEROSPACE STRUCTURES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17828291 titled 'METHODS OF APPLYING BOND PRIMER COMPOSITIONS FOR BONDED AEROSPACE STRUCTURES

Simplified Explanation

The patent application describes a method for applying a bond primer composition to a metal surface of an aerospace part.

  • The method involves creating a multilayer bond primer structure by applying multiple layers of the bond primer composition onto the metal surface.
  • A foam applicator is used to apply the first sublayer of the bond primer composition.
  • The first sublayer is then heated before applying the second sublayer.
  • The second sublayer is also heated before applying the final sublayer.
  • The final sublayer is applied onto an underlying sublayer of the multilayer bond primer structure.
  • The multilayer bond primer structure is then cured to form a bond primer coating that adheres to the metal surface.


Original Abstract Submitted

Methods of applying a bond primer composition to a metal surface of an aerospace part are provided which may comprise forming a multilayer bond primer structure by (a) applying a first sublayer of a bond primer composition onto a metal surface of an aerospace part using a foam applicator comprising the bond primer composition; (b) heating the first sublayer; (c) applying a second sublayer of the bond primer composition onto the first sublayer; (d) heating the second sublayer; (e) applying a final sublayer of the bond primer composition onto an underlying sublayer of the multilayer bond primer structure; and curing the multilayer bond primer structure to form a bond primer coating adhered to the metal surface.
