Kit-of-parts for curable polyaspartic acid ester-based coating compositions

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.
