Disclosed are methods of preparing thiol keratin-containing materials, comprising applying a mixture comprising one or more thiol compounds and a catalyst. Methods of preparing cross-linked keratin-containing materials by applying a mixture comprising one or more thiol compounds and an oxidizing agent are also disclosed. Methods of grafting monomeric and polymeric materials on keratin-containing materials to provide a covalent coating on keratin-containing materials are disclosed. A mixture comprising one or more thiol compounds is applied to the keratin-containing material sample. The keratin-containing material sample then comprises a plurality of free thiol groups. A monomer is optionally applied to the keratin-containing material sample to form a plurality of covalent bonds between the free thiol groups and the monomers. The disclosed grafting methods can be carried out with or without catalyst.

Techniques and compositions for applying films to a variety of substrates, from water-borne coating compositions, are provided. The techniques involve providing desiccant and applying the desiccant with water-borne film-forming composition, in application to a substrate. The desiccant composition provides for take up of free water in of the film-forming composition, without total reliance on ambient conditions, to advantage. Compositions, methods, techniques and resulting constructions are described. The techniques can be applied in wet thick film applications, but are not limited to such applications.

A composite material comprising a metallic substrate and a coating on at least one side of the metallic substrate, wherein the coating comprises an acrylic or styrene-acrylic based polymer and is less than about 0.2 mils thick, wherein the polymer has a molecular weight of 50,000 to 1,000,000, a glass transition temperature (Tg) of 50-80 C., and comprises 90-100 wt. % of the total solids in the coating. The method of applying a coating to a metal substrate using a manifold flood and squeegee roll configuration or alternatively roll coater techniques; wherein the roll hardness, shape, pressure and speed are chosen to ensure that the coating composition forms a continuous wet film on the metallic substrate surfaces when the strip travels at up to 600 feet per minute; and the wet film has a uniform thickness of 2 mil (0.002 inch) or less.

The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection infrared range of the electromagnetic spectrum reduce heating by sunlight in the near infrared dark tinting in the visible range. Low density conductivity are obtained inter alia by inserting in the near in order to area despite and low heat light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.
