摘要:
A composition for producing a putty. The composition includes a binder component with 40 to 95 wt.-% of an epoxy resin based on a total mass of the binder component, a hardener component with 5 to 70 wt.-% of an NH-group-containing compound relative to a total mass of the hardener component, and 0.1 to 15 wt.-% of synthetic hollow bodies based on a total mass of the putty. The synthetic hollow bodies have a density of 0.005 to 0.8 g/cm3
摘要:
Curable compositions are prepared from polyol components containing one or more polyols and isocyanate components containing one or more isocyanates, which compositions contain at least one indicator having at least one quinonoid group, which indicator signifies the degree of curing by a change of color. A method is also provided for indicating the progress of curing in such curable compositions.
摘要:
There are several coatings and a method for surface finishing, in particular for producing durable and stable surface coatings using ink jet printing methods. The coating 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.

The invention relates to curable compositions which are prepared from polyol components containing one or more polyols and isocyanate components containing one or more isocyanates, which compositions contain at least one indicator having at least one quinonoid group, which indicator signifies the degree of curing by a change of color. The invention also relates to a method for indicating the progress of curing in such curable compositions.
摘要:
A process for the control and/or guidance of welds in electric arc welding wherein a metal or a metal alloy is applied to the edge or surface to be welded of at least one workpiece, with the metal or at least one of the principal alloying metals not being present in the workpiece or at least in slight proportions only, so that a characteristic spectral line emitted by at least one of the metals applied is observed spectroanalytically in the arc and that the weld is controlled and/or the arc guided by means of the spectral data determined.
摘要:
A coating system includes at least one putty layer and at least one clear coat layer. The at least one putty layer includes a putty having a binder component which has at least one polyaspartic acid ester and a hardener component which has at least one polyisocyanate. The at least one clear coat layer includes a clear coat coating material based on an RMA binder or a polyaspartic acid ester binder.
摘要:
A coating material for the production of a UV-curing primer coating. The coating material includes 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 carbonyl-functional acrylate and/or at least one methacrylate oligomer or 5 to 15 wt.-% of at least one polyethylene glycol acrylate and/or at least one polyethylene glycol methacrylate, and 1 to 10 wt.-% of at least one photoinitiator, each based on a total weight of the coating material.
摘要:
Coating a metallic surface with at least one of a pretreatment composition prior to organic coating, with a passivation composition without intent for subsequent organic coating, with a pretreatment primer composition, with a primer composition, with a paint composition and with an electrocoating composition, wherein the coating composition includes particles on a base of at least one layered double hydroxide (LDH) phase characterized by the general formula [M2+(1±0.5)−x(M3+, M4+)x(OH)2±0.75]An−x/n.mH2O.
摘要:
The present invention relates to a chromate-free composition, to the use thereof for corrosion protection, and to a corrosion protection coating for the inside surfaces of fuel tanks, wherein the composition comprises binding agents, hardening agents, corrosion inhibitors and quaternary ammonium compounds in a quantity of at least 0.1% by weight.
