    摘要: A two-component composition for the production of gelcoats is disclosed, comprising, in addition to a polyisocyanate component, a specially-formulated polyol component. The latter contains one or more low molecular weight polyols, one or more high molecular weight polyols and one or more light-resistant aromatic amines. Gelcoats with very good working properties can be achieved with said two component composition, in particular with long lamination time, very good adhesion to the applied laminate and excellent surface and stability properties which meet the requirements of moulded pieces such as aerofoils. The invention further relates to the use of particular light-resistant aromatic amines in a polyol component to increase the lamination time on application in a polyurethane gelcoat for coating epoxy laminates, a method for production of polyurethane gelcoats and a composite material comprising said gelcoat.
