A container system for pasty compositions includes one or more cylindrical hollow bodies each having a removable base plate and a removable lid. In particular, the container system includes two containers, each separately holding one of the components for the production of a two-component putty. The ratio of the dimensions of the two containers in terms of their capacity or their volume is equal to the ratio by weight or by volume in which the two components are used. Further, a method produces a curable putty using this container system in which the components of the composition are almost totally removed from the containers and are intermixed to form a homogeneous substance, which is then processed.

The present invention relates to coatings and to a method for surface finishing, in particular for producing durable and stable surface coatings using ink jet printing methods. The coating according to the invention comprises a first layer, which can be produced from one or more ink jet-capable inks, and a second layer, which can be produced from one or more top coats, wherein at least the first layer is applied using an ink jet print head.
摘要:
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.
摘要:
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.
摘要:
A coating system for the decoration of a recyclable plastic substrate. The coating system includes a primer layer and a decorative layer. The primer layer includes at least one coating which is made from at least one coating material having 60 to 80 wt.-% of at least one difunctional, alcoxylated acrylate monomer, 5 to 15 wt.-% of at least one acrylate oligomer, 5 to 15 wt.-% of at least one of at least one carbonyl-functional acrylate and at least one methacrylate oligomer or 5 to 15 wt.-% of at least one of at least one polyethylene glycol acrylate and at least one polyethylene glycol methacrylate, and 1 to 10 wt.-% of at least one photoinitiator, each of which are based on a total weight of the coating material.
摘要:
Coating material compositions are used for producing particularly erosion-stable coatings which are used as erosion protection, in particular as edge protection for rotor blades. The composition includes a stock component and a hardener component, wherein the stock component includes at least one trifunctional polycaprolactone polyol or at least one polycarbonate diol or at least one trifunctional polycaprolactone polyol and a polycarbonate diol and the hardener component includes at least one crystallization-resistant, isocyanate-functional prepolymer.
摘要:
A coating material includes 10 to 30 wt.-% of a polyol, 2 to 15 wt.-% of an etherified melamine-formaldehyde resin, 0.1 to 10 wt.-% of an acid catalyst, and at least one of a flame retardant, a filler, and a pigment in an amount to obtain a filler content in a range of from 60 to 80 wt.-% based on an overall mass of the coating material. The flame retardant is selected from the group consisting of an inorganic flame retardant, a halogenated flame retardant, a nitrified flame retardant, a boracic flame retardant, an intumescent flame retardant, and mixtures thereof.
