Abstract
Official abstract text for this publication.
Disclosed is a composition comprising at least one polyol component (a) having an OH group content of 3% to 15% by weight relative to the total weight of the polyol component, and at least one isocyanate component (b) having an isocyanate group content of 5% to 15% by weight relative to the total weight of the isocyanate component. The polyol component (a) comprises at least one OH group-containing polyurethane prepolymer that is the product of a reaction between at least one compound a1. of the general formula (I) HO—R 1 —X—R 2 —OH (I) and at least one di- or polyisocyanate a2. The isocyanate component (b) comprises at least one di- or polyisocyanate-terminated polylactone prepolymer. The composition can be used as erosion-resistant coating material.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: (a). at least one polyol component comprising at least one OH group-containing polyurethane prepolymer which is a product of a reaction between a1. at least one compound of general formula (I) HO—R 1 —X—R 2 —OH (I) wherein R 1 and R 2 independently of one another are a branched or unbranched alkylene group having 1 to 10 carbon atoms, X is S, S—S, NR 3 or 0, R 3 is a branched or unbranched alkyl group having 1…
