| 摘要 |
This invention relates to a moisture-curable coating composition capable of curing at ambient temperature and comprising (a) an isocyanate functionalised prepolymer derivable from reacting a di- or poly-isocyanate with a functionalised polybutadiene having a functionality of at least 2, (b) an isocyanate and (c) an oxazolidine, a ketimine or an aldimine as curing agents. The coatings produced using the compositions of the present invention have improved impact resistance and surface tolerance. |
