Abstract: The invention relates to an anti-corrosion agent with an aqueous base and a method for the production thereof. The water-based anti-corrosion agent is a cavity preservation agent, a means for underbody protection coating, a means for permanent storage and transport protection coating, or a means for temporary storage and transport protection coating, wherein the anti-corrosion agent is provided for anti-corrosion protection for a component, in particular a motor vehicle component, wherein the anti-corrosion agent can be applied cold, is reversibly gelling and physically drying, even in thick layers, is rheologically controllable and can be adjusted in an application-oriented manner.

Abstract: A press die for a pressing tool for pressing round tubular sections of at least two workpieces has a through-hole with a circumferential die surface. It includes at least two die parts. Each of the at least two die parts comprises a circumferential section of the through-hole. At least one of the die parts comprises a round target contour over at least one region of the associated circumferential section of the through-hole. At least one other die part comprises a contour deviating from the round target contour over at least one region of the associated circumferential section of the through-hole. Thus, the circumferential sections of the through-hole associated with the at least two die parts are asymmetrical relative to each other with respect to a chord formed by the associated circumferential section of the through-hole.
