Abstract: Disclosed herein is a kit-of-parts for preparation of a curable coating composition including in a first container an isocyanate-reactive compound (A) including a polyaspartic acid ester compound, in a second container a polyisocyanate (B), and in a third container a solvent (S1) selected from the group consisting of monoalcohols and alkoxymonoalcohols, where UVA and/or HALS additives are optionally contained in the first and/or third container, and a second solvent (S2) is optionally contained in the second or third container. Further disclosed herein are a coating composition prepared from the kit-of-parts, a process for preparing at least one coating on an optionally pretreated and optionally precoated substrate, and coated substrates derived therefrom.

Abstract: A sliding electrical contact part is disclosed. The contact part includes a base of carbonaceous material and copper. The contact part is lead-free and contains zinc and iron-base particles having a size less than 500 ?m. The contact part is particularly suitable for electrical devices which require high friction densities and friction velocities, such as motor vehicle starters with a high power-to-weight ratio.

Abstract: A sliding electrical contact part comprising a base containing carbon, copper, zinc and iron, wherein said part is multi-layer, with at least one layer composed of a material with a low electrical resistivity and at least one layer composed of a material with a higher electrical resistivity, the material comprising the layer with a low electrical resistivity containing zinc and iron based particles, whose size is less than 500 ?m.
