Abstract: The invention relates to mold-release agents, in particular mold-release agents which can be used for demolding moldings from molding tools, and also to the use of these mold-release agents. The mold-release agents of the invention, which are preferably based on suspensions of nanostructured microparticles, have the advantage of being markedly more environmentally compatible than the known mold-release agents based on organic or organosilicon compounds, since they can remain on the surfaces of the moldings. The use of the mold-release agents of the invention is very simple, since advantage can be taken of existing equipment. An example of a usual method is to produce injection moldings by means of injection molds into which the material is injected. The mold-release agent of the invention is applied, e.g. by spray-application, to the injection mold prior to the actual injection-molding process.

Abstract: A self-regenerating, self-cleaning hydrophobic surface is formed when particles are secured on a carrier that is itself a mixture of particles and binder. When particles on the surface are ablated by erosion, new particles in the carrier are exposed to regenerate the self-cleaning surface, resulting in a long-lasting self-cleaning action. The self-cleaning surface may be used with particular advantage outdoors, e.g. on vehicles, where self-cleaning materials are particularly exposed to the effects of the environment.
