    摘要: The invention relates to a two-component coating system and a preparation method and use thereof, as well as grout or caulk comprising the coating system. The two-component coating system comprises component A comprising a polyaspartic acid ester and component B comprising a polyisocyanate, wherein the polyisocyanate has isocyanate functionality of not less than 4, and the polyisocyanate comprises allophanate groups and isocyanurate groups, and the ratio of moles of the allophanate groups to the sum of moles of the isocyanurate groups and the allophanate groups is of not less than 65:100. The two-component coating system of the present invention forms a coating with small bubble area and good resistance to yellowing and to stain resistance.
