Abstract
A method of visually verifying the application of a primer or adhesion promoter to a surface for optimizing the adhesion of a bonding tape to the surface. A fluorescing agent is mixed with the primer and a light source is emitted on the surface causing the agent to fluoresce when the primer is applied. The technician can then visually verify coverage of the primer. The fluorescing agent does not affect the bonding properties of the bonding tape or affect the aesthetic appearance of the surface or the material being bonded to the surface.
Claims7
A method for applying a primer to a radome surface for optimizing adhesion of a very high bond tape to the radome surface, the method comprising the steps of:
- mixing a fluorescent agent with the primer;
- applying the mixed primer and fluorescing agent to an inner surface of the radome;
- emitting a light on the surface;
- visually inspecting the application the mixed primer and fluorescing agent for adequate coverage;
- and
- pressing a very high bond tape onto the inner surface of the radome.
A method for bonding a cup to a radome, the method comprising the steps of:
- applying a very high bond tape to the cup;
- mixing a fluorescing agent with a primer;
- applying the mixed fluorescing agent and primer on an inner surface of the radome;
- emitting an ultraviolet light on the radome;
- visually inspecting the application;
- and
- pressing the cup directly onto the inner surface of the radome.
