Abstract:

The patent application pertains to a sprayable material for aircraft skin fastener head areas which is formed from a fully saturated prepolymer that is a reaction product of polytetramethylene ether glycol and 2,4 toluene di- isocyanate. The prepolymer is mixed with toluene to form a first mixture. This first mixture is combined with a second mixture of 4,4 methylene-bis-2- chloroaniline and urethane grade methyl ethyl ketone. The sprayable material is applied over an epoxy-polyamide primer coating covered by a metal pretreatment coating compound. An aliphatic polyurethane coating is then applied over the sprayable material.
