  • Patent number: 9764817
    Abstract: The invention relates to a method for covering light aircraft and/or parts thereof with a polyester covering fabric, and to a dispersion hot-melt adhesive and to the use thereof for covering. The invention further relates to a light aircraft or to a part of the same which is covered with a polyester covering fabric by means of the method according to the invention.
    Type: Grant

  • Patent number: 9279216
    Abstract: The present invention relates to a covering fabric for covering aircraft. The fabric itself may be coated with one or more layers of a crosslinked anionic aliphatic polyester-polyurethane dispersion and/or is woven from coated fibers or filaments. A covering fabric of the invention may be glued using a thermoactivatable heat-crosslinking adhesive. An advantage of the covering fabric of the invention is that there is no need for further coating of the fabric after covering, and thus significantly less weight is applied by the covering process. Furthermore, the user is able to apply the covering to an aircraft without using any organic solvents in adhesives, tension-inducing varnishes, thinners, fillers or colored varnishes. Thus, an environmentally friendly process is provided for the covering of aircraft.

  • Patent number: 6548428
    Abstract: The invention consists of a multilayer material and a process for manufacturing this material. The multilayer material comprises a polyester substrate which is provided with a thermoset plastic polymer coating and a layer of contact adhesive. The polymer coating is produced by a reaction between a polyurethane polymer containing hydroxyl groups and a low molecular linear polyisocyanate, with catalytic tin-organic additives and colorants. The multilayer material is resistant to tearing and is also weather-resistant. A transparent, reactive layer, consisting, for example of a layer to take toner or ink, or a metallic layer, can be deposited on the side opposite to the polymer-coated substrate. Multilayer materials of this kind are suitable for large-scale covering of supporting frameworks in the construction of model aircraft and are also suitable as a medium onto which images and print may be applied using a plain paper copier, and can also be used to carry advertising.
