Surfactants useful for enhancing the electrical conduction of electrodes attached to the surface of a patient. The surfactants are also useful in transport of materials in and out of the body of a patient (animal or human) and in the measurement of disease states. Typical surfactants particularly useful in the invention are broadly represented by protein/fatty acid based compounds. The protein/fatty acid compounds may be lipopolypeptides. In some embodiments the lipopolypeptides may be acyl peptides. Typical acyl peptides are Lamepon S&#x2122;, MayTein C&#x2122; and MayTein CT&#x2122;.

Skin conduction and transport systems

The concept of a barrier coating is applicable to any structure that requires repetitive paint removal. In principle, the coating is applied between a corrosion protective primer and protective topcoat for the purpose of encapsulating the corrosion resistant properties of the primer/surface treatment and allowing for a selective removal of the topcoat using acceptable mechanical coatings removal techniques. The 5-part coating system can be used on any type of structure that requires routine maintenance or repainting to preserve the integrity and/or appearance of the structure. Benefits associated with the concept of barrier coating include a significant reduction in the costs and manpower required to remove and reapply primer and topcoat systems from air- and land-based transportation vehicles, storage buildings, bridges and miscellaneous other structural applications. A second important benefit includes a reduction and/or elimination of the environmental hazards associated with (1) the treatment and disposal of primer and surface treatment residues (chromates, etc.), and (2) the release of toxic airborne pollutants during the precleaning, paint stripping, and painting operations conducted on large structures, thus limiting the exposure of workers.

Protective barrier coating for selective paint stripping processes

An intumescent coating system and method therefor is disclosed for thermally protecting a substrate having a surface exposed to fire conditions. The coating system of the present invention is provided as having a having a first film layer which forms a rigid carbonific char foam having toughness and rigidity, and a second film layer which forms an insulative carbonific char foam having insulation properties. The two foam components may be separately provided in a laminate-type arrangement as, respectively, an inner coating layer coated and cured on the surface of the substrate to form an inner film layer, and an outer coating layer coated and cured on the inner film layer to form an outer film layer. In providing two foam components, one protecting the substrate from breakthrough and direct exposure to the fire conditions, and the other insulating the substrate to protect it from conductive, radiant, and/or convective heating by the fire conditions, the present invention affords a capability to offer flame retardancy at film thicknesses of 1.27 mm (50 mils) or less.

Thermally-protective intumescent coating

An intumescent coating system and method therefor is disclosed for thermally protecting a substrate having a surface exposed to a flame environment. The coating system of the present invention is provided as having a having a first component which forms a rigid carbonific char foam having toughness and rigidity, and a second component which forms an insulative carbonific char foam having a density about half the density of the rigid carbonific foam to give insulation properties. The two foam components may be separately provided in a laminate-type arrangement as, respectively, an inner coating layer coated and cured on the surface of the substrate to form an inner film layer, and an outer coating layer coated and cured on the inner film layer to form an outer film layer. Alternatively, the two foams may be provided as being formed from components blended to comprise a single coating layer which is coated and cured on the surface of the substrate to form a film layer. In providing two foam components, one protecting the substrate from breakthrough and direct exposure to the flame environment, and the other insulating the substrate to protect it from conductive, radiant, and/or convective heating by the flame environment, the present invention affords a capability to offer flame retardancy at film thicknesses of less than 50 mils.
