Abstract: Systems, apparatuses and methods for rapidly evaluating light transmission through coatings including paints, primers, thin films, surfacing films, laminates and the like are disclosed. The system includes a light source for transmitting light through a coating sample. A sample holder holds the coating sample in a position to receive the incident light. A spectrometer measures an amount of the transmitted light that passes through the coating sample. Optionally, one or more optical filters may be used to condition any transmitted light that passes through the coating sample to reduce the intensity of the light outside of wavelengths of interest. An opaque cover encloses the spectrometer, the one or more optional optical filters, and at least part of the sample holder to prevent light other than the transmitted light from the light source from entering the spectrometer such that any transmitted light passing through the coating sample can be accurately evaluated.

Abstract: The present invention relates to a method of activating an organic coating to enhance adhesion of the coating to a further coating and/or to other entities comprising applying a solvent and a surface chemistry and/or surface topography modifying agent to the organic coating. The invention also relates to a coated substrate having an activated coating, wherein the adhesion of the coating to a further coating and/or other entities has been enhanced by application of a solvent and a surface chemistry and/or surface topography modifying agent to the coating. The invention further relates to an activation treatment for an organic coating to enhance adhesion of the coating to a further coating and/or to other entities comprising a solvent and a surface chemistry and/or surface topography modifying agent and a method for the preparation of the activation treatment.

Abstract: The present invention includes a process using environmentally benign materials for the removal of adhesive residues from hard substrates, particularly vehicles, e.g., cars, trucks, buses, aerospace vehicles including airplanes, and the like. The invention uses an absorbable indicator (tracer) dye to aid in detection of remaining residues that may be in need of additional cleaning. The process uses a novel adhesive remover composition comprising a non-halogenated organic solvent, a non-abrasive thickening agent, a surfactant, glycerine, and an absorbable indicator dye. The invention provides a cost effective, safe, environmentally friendly adhesive remover composition specifically formulated for removal of, e.g., pressure sensitive adhesive residues from large areas of aircraft composite and aluminum surfaces, as well as others.

Abstract: A lightning protection system for protecting composite structures and a method of protecting composite structures from lightning strikes. A dielectric ply is fixed above and completely covers metal surface features, e.g., skin fasteners through a composite skin to a wing fuel tank. A conductive ply is fixed above and completely covers the dielectric ply and extends to an external connection to a platform ground. The conductive ply directs current from lightning strikes away from metal surface features, e.g., to the platform ground. Both plies may be adhesively backed and sequentially pressed into place.
