The invention concerns a method for producing removable surface protection by the application of a curable, liquid coating composition (liquid film), in which the surface is treated using water, or an aqueous solution of surface-active agents, and the coating composition is subsequently applied. Preferably, the surface is the topcoat of a motor vehicle. The invention further relates to the use of water or aqueous solutions of surface-active agents in such a method. Finally, the invention also relates to a removable surface protection coating of this nature. According to the invention, the flow of the coating composition into a uniform film is improved.

Method for the application of a liquid film after aqueous pretreatment of the surface to be coated

Process for controlling and/or guiding the weld seam during arc welding

A molding material based on polyisocyanato-isocyanurates, polyols and flameproofing and fireproofing agents, as well as optionally polyisocyanates, fillers and promoters is described which is preferably in the form of a 2-component material and comprises 5 to 40% by weight of branched polyols, 20 to 40% by weight of the isocyanurate of 1,6-hexamethylene diisocyanate, 0 to 20% by weight of crude MDI and/or prepolymer of polyol and crude MDI and/or isophorone diisocyanate optionally in combination with further isocyanate groups containing compounds, 5 to 20% by weight of a fireproofing mixture mainly consisting of secondary ammonium phosphate, 0 to 50% by weight filler and 0 to 5% by weight promoter. This mass, which permits quick processing at room temperature or slighty increased temperatures, is useful as construction and repair material for many applications, especially in connection with the construction and repair of land, air and water vehicles. The products obtained after curing meet the highest requirements with regard to fire protection and possess excellent mechanical properties.
