以下是聚脲涂料的成分與性能分析：

　　The following is the analysis of composition and properties of polyurea coatings:

　　聚脲涂料主要是由異氰酸酯組分和聚醚胺的組合料組成的，現(xiàn)有的聚脲原材料主要由MDI、聚醚多元 胺、聚醚多元醇、胺擴(kuò)鏈劑、各種功能助劑、顏填料、活性稀釋劑等組成。

　　Spray polyurea coating is mainly composed of isocyanate group and polyether amine compound consisting of existing polyurea raw materials mainly by the composition of MDI, polyether polyamine, polyether polyol, polyamine chain extender, each kind of function additives, pigments and fillers, active diluent.
